For this current event article I read “The Golden State Killer Is Tracked Through a Thicket of DNA, and Experts Shudder” written by Gina Kolata. The article discussed  how popular genetic testing has become, such as companies like 23and me. However these types of websites were able to assist police detectives in a criminal case. Although the police used a public genealogy database, they were able to catch the seventy two year old Joseph James DeAngelo, there were of course ethical and privacy issues in the way they were able to catch him. This issue made people question if the way he was captured was justified or not. However the Golden State killer is linked to more than fifty rapes and twelve murders between the time periods of 1976 and 1986. He managed to escape everytime, in my personal opinion the people he has harmed and effected deserve justice for the trauma he has caused, if the police had to allude privacy issues to do it, so be it.


This article has a massive impact on today's time, there are still many people who go with family members or friends who have suffered without justice. With the popularity of genetic background test, it makes it easier to find criminals who alluded their crimes for some time. It becomes apparent that these issues need to brought the attention of the public, if the people are comfortable with a little less privacy in order for others to receive justice. Just as Peter Neufeld said “There is a whole generation that says, ‘I don’t really care about privacy,” making it clear that a vast majority of people don't mind the invasion.

This article was really interesting and informative to read, It was interesting to see the massive effect that everyday easy DNA kits have the capability of connecting a variety of people together, and in this case to a criminal. The author did a great job with adding quotes from outside sources on different perspectives of the matter. However if the author added more background information on the criminal, if he went into more depth with what he did exactly, it would have made for a stronger case.

To Catch a Killer: A Fake Profile on a DNA Site and a Pristine Sample

The article “To Catch a Killer: A Fake Profile on a DNA Site and a Pristine Sample” by Tim Arango, talks about how in an attempt to catch a killer forensic analysts created a DNA profile for a perpetrator after decades of the case being cold. They used the DNA found at the scene and recreated what the suspects genealogy would have been. After making this fake DNA profile they found out a few candidates for who the rapist could have been. Although at first not everyone was on board with using this DNA profile to catch him but after chasing down countless suspects over the last decade they decided that anything was worth a shot. It took 4 months from the time of completion of the profile to the arrest of the prime suspect, 72 year old Mr. DeAngelo. The investigators involved were shocked by how well this profile worked after coming up short for years. The real problem using the DNA was that since the 1980’s the DNA has begun to disintegrate. Luckily there was another set of DNA still in the freezer. Mr. DeAngelo was not charged for the rape cases as the statute of limitations have expired but he will still be prosecuted for a number of murders.
This new method of investigation opens up the door to countless possibilities in the field of forensics. This means that we can recreate DNA profiles to find the perpetrator and give closure to families even if they can't be arrested due to the statute of limitations. The article also talks about how these profiles help to pick up the slack from when the police run into a wall in their investigations. The profiles are useful with identifying murderers or rapists or burglars or really any crime that leaves behind any salvageable DNA.

Overall the article was pretty cool. However I wish that the author talked about how the creation of the DNA profiles. The article talks about how it helps to create the profile but never discusses how the creation of the profile occurs.

Golden State Killer Caught Through GEDmatch Search, Officials Say, as Arraignment Approaches

Augenstein, Seth. “Golden State Killer Caught Through GEDmatch Search, Officials Say, as Arraignment Approaches.” Forensic Magazine, © Copyright 2018 Advantage Business Marketing, 27 Apr. 2018, www.forensicmag.com/news/2018/04/golden-state-killer-caught-through-gedmatch-search-officials-say-arraignment-approaches.


In “Golden State Killer Caught Through GEDmatch Search, Officials Say, as Arraignment Approaches”, author Seth Augenstein states that The Golden State Killer, Joseph DeAngelo, terrorized California communities from the mid 1970s to mid 80s by raping 45 people and killing 12 people in their own beds. His spree ended right before DNA revolutionized forensics. However, a DNA genealogy database known as GEDmatch ultimately helped investigators track DeAngelo down since they could pick him out as a suspect from the database and compare it to DNA left at the crime scenes. GEDmatch also helped solve other decades-old serial killer cases, identifying the “Chameleon” serial killer, Teddy Peder Rasmussen, and the “Buck Skin Girl” of Ohio, Marcia King. What makes the Golden State Killer case so important is that the defense will likely contend that the use of GEDmatch violates the 4th Amendment (“Unreasonable Search and Seizure”). The unusual aspect of GEDmatch is that it does not look for the genealogy of relatives of the suspect by examining those in his/her family who committed crimes, like CODIS, but rather the genealogy of relatives who uploaded data to Ancestry or other family tree services that wanted to match this data with people outside their own service. To get around issues that can be presented as a defense in a court case regarding the privacy of the ancestors uploading data, GEDmatch informs its users that the uploaded data may be used for things other than genealogy, such as to solve criminal cases of the “Golden State Killer” nature.  Sacramento County District Attorney credited with organizing the task force to make the “Golden State Killer” breakthrough, Anne Marie Schubert, stated that the developments leading to the arrest of DeAngelo took place in only six days.
What this article shows is that what makes forensics grow in its effectiveness is advancements in other sciences and technologies increasing the breadth of available data on a case. The more individuals leave their personal information online, the more can be searched through to implicate criminals. This article also shows that the best way to secure an individual’s privacy is by making it compulsory that every online service tells users exactly how the personal information they upload can potentially be used. By informing the consumer, this ensures that users can decide how private they want their personal information while still allowing for the growth of efficiency in solving many important cases. This is why I do not think that the defense will have any meaningful case during the arraignment. Such precautions were already taken to not violate the 4th Amendment.
A strength of this article was that it was extremely detailed in what exactly GEDmatch does to obtain the genetic data of suspect ancestors, how it is different from more common databases like CODIS and the precautions taken by GEDmatch to not violate the 4th Amendment. All of these details are relevant to forensics overall, allowing readers to know what exactly was improved in the field. However, one weakness of the article was that it did not describe why so many people think that DeAngelo’s defense will challenged due to privacy concerns. If GEDmatch already took steps to inform its users that their data may be used for criminal cases, how would that defense work? The article would have been improved by adding that explanation, since it would shed light on the significance of this particular case.

Gene expression patterns may help determine time of death

Center for Genomic Regulation. "Gene expression patterns may help determine time of death."
ScienceDaily. ScienceDaily, 13 February 2018.
<www.sciencedaily.com/releases/2018/02/180213132941.htm>


For my current event article, I decided to read and analyze the article “Gene expression
patterns may help determine time of death,” from the online news source Science
Daily. The article discusses the discovery in which scientists can see the time of
death of an individual by examining the changed gene expressions. The scientists
involved are able to examine tissue samples from the deceased and determine the
time of death of said individual with strikingly good accuracy. The study is being
led by Roderic Guigó at the Center for Genomic Regulation.  The study led the
researchers involved to use the GTEx system. The GTEx system is one that,
“aimed at creating a reference database and tissue bank for scientists to study how
genomic variants affect gene activity and disease susceptibility.” The GTEx was
useful as it provided the scientists involved with reference samples. Roderic
Guigó and his team were able to find out about the change in gene expression after
death by thoroughly examining RNA-sequencing data from approximately 7,000
samples. “We found that many genes change expression over relatively short
post-mortem intervals, in a largely tissue specific manner. This information
helps us to better understand variation and also it allows us to identify the
transcriptional events triggered by death in an organism,” mentioned Pedro G.
Ferreira, a scientist working on the study.


Considering the fact that this article concerns the study of determining the exact
time of death, it is very important to the world of forensic science. If the method
is perfected and dispersed among law enforcement institutions across the world,
then the processes of determining the time of death will become much easier. This
can lead to quicker arrests and more trustworthy evidence to be offered during court
trials. It would also surely lead to a safer world as arrests would be much more
definite and conclusive. Despite this, it is evident that the system still has a long
way to go before it will be properly introduced into the world of forensic investigation.


Overall, I believe that the article “Gene expression patterns may help determine
time of death,” from the online news source Science Daily was extremely well
written and equally informative. The authors were able to describe the complicated
and advanced system developed while relating back to it’s uses and how it could
deeply change the world of forensic science. The authors go into amazing detail
surrounding the exact functions and why the system needs further development
before it will be properly introduced into the world of forensic science. In an effort
to improve the article, the authors should have supplied the reader with more
information concerning how the process literally works. It would have been
interesting to know when exactly the researchers estimate the system will be
introduced after further testing and trials. The authors could have also further
improved the article by describing the ideas behind the creation of the process
and how, exactly, it came to be.

"Forensics Helps Widen Architecture's Mission"



Forensic Architecture is a research group which uses architectural rendering software to investigate cases for lies, crimes and human rights violations. Eyal Weizman, the founder of the research group stated that “When a state commits a crime, it cordons off an area, which is the privilege of the state. That site becomes a work of architecture, defined by the cordon. A prison by definition is architecture. You can try to break through the state cordon via leaks, media images, satellite photographs. And when they’re not available, memory is a way around the cordon. In any case, the cordoned area is our ‘building site.’” When asked about how Forensic Architecture related to the work of an architect, Christina Varvia, Forensic Architecture research coordinator stated that “What we do is in the tradition of ‘paper architecture. Except we expect results. As architects, we’re also trained to bring different people together to produce a design. But instead, we synthesize evidence.” In London of last year, a Bedouin village was raided by Israeli police officers called Umm al-Hiran. Authorities said that during the raid, a villager intentionally ran over an Israeli officer, killing him, and they called it a terrorist attack. To look further into the case, the research group worked with ActiveStills, an Israeli-based photographic collective. Forensic Architecture used photogrammetry and collected, time-stamped and synchronized the images and videos of the raid to produce a virtual reenactment of the scene to be compared to the helicopter footage.
Forensic Architecture plays an important role in society, as it takes advantage of the rapid advances in technology. By being able to virtually reconstruct a crime gives investigators a huge advantage, especially if the evidence they were given, such as film footage, was not good quality nor was it clear enough to see exactly what happened. As there are more crimes, the ability to reconstruct a scene, taking a deeper look into the crime, decreases the chance of being falsely accused for a crime, when in fact that person did not do anything wrong.

The article, “Forensics Helps Widen Architecture's Mission,” was very interesting to read, and I learned more about the role virtual reproductions of crimes impact forensic science. However, I wished that the author had gotten more into depth regarding the forensic side of Forensic Architecture rather than focusing solely on the cases that they solved. I wished that Kimmelman had described the forensic process in more depth as well.

“Can Estimates From Forensic Handwriting Experts Be Trusted in Court?”

Springer. “Can Estimates From Forensic Handwriting Experts Be Trusted in Court?” Forensic Magazine, 18 Apr. 2018, www.forensicmag.com/news/2018/04/can-estimates-forensic-handwriting-experts-be-trusted-court.

In the article, “Can Estimates From Forensic Handwriting Experts Be Trusted in Court?” Springer discusses the amount of trust we should put into handwriting experts.  These experts are brought into court to reveal the origins of a few lines of writing, or to determine whether a specific person has written a sentence. They also discuss the probability of a specific person writing a specific sentence or word. However new research led by Kristy Martire of the University of New South Wales in Australia reveals that maybe we shouldn’t be so trusting with experts. In this study Martire brought in eighteen court-practicing handwriting specialists (eight practicing in the US), and 77 people (36 from the US) with no previous training or experience in analyzing handwriting. All participants were given samples of handwriting and asked to examine them. According to Springer, “The researchers found that experts are marginally better than novices at estimating how often specific handwriting features occur in the writing of the general population, but they are not able to do so with complete accuracy. However, the estimations given by handwriting experts do reflect a level of knowledge and skill.” It was also reported that US experts performed at a higher rate than the other experts. However according to Mature one thing was clear, “The overall error rate even for experts is large enough as to raise questions about whether their estimates can be sufficiently trustworthy for presentation in courts."
I found this article to be very interesting and of complete relevance to our forensics class. Handwriting analysis is a large part of forensics and the analysis of it. The fact that we might not be able to trust these experts could call many cases’ verdicts into question. I also was interested in a personal level however because it made me wonder how I would test in relation to these experts.

Overall I thought this was a really article. Even though it was short, the author did a good job of explaining the situation and the research that led to this new idea. I do wish they would have presented some solutions to better equip /inform these experts so that we can continue to put our trust in them. I also wish they could’ve gone into further details in terms of what exactly the subjects were examining within the study.

“Second Lab Scandal in Mass. Leads to 11,000 Case Dismissals: ACLU.”

Augenstein, Seth. “Second Lab Scandal in Mass. Leads to 11,000 Case Dismissals: ACLU.”

In the article “Second Lab Scandal in Mass. Leads to 11,000 Case Dismissals: ACLU,” Seth Augenstein writes about how a second forensic laboratory scandal in Massachusetts will result in over 11,0000 dismissed convictions within an estimated 7,690 cases. These cases were tainted by former forensic chemist Sonja Farak, who used drugs she stole or manufactured at the Amherst laboratory. Investigators have said Farak was high almost everyday of the nine years she worked at the state crime lab. The ACLU, the Committee for Public Counsel Services and the law firm Fick and Marx, LLP filed a petition last fall to dismiss every case handled by Farak. Rebecca Jacobstein, staff attorney for the CPCS said, “We have asked the court to dismiss the remaining cases where Farak signed the drug certificate of analysis. In addition, we have asked the court to dismiss all Amherst Lab cases during Farak’s tenure, because her misconduct was not limited to cases where she signed the drug certificate of analysis, but impacted all cases at the Amherst lab.”
This subject of this article has had a detrimental and shameful result on forensics. Sonja Farak was trusted with valuable evidence that she was supposed to examine in a very specific way in order to connect individuals to evidence in a clear, scientifically valid manner. Her actions and her careless involvement with serious drugs while working at a crime lab means that over 11,000 convictions will probably be dismissed. Some of these people are guilty of the crime they committed and some are probably innocent. In addition, this is only the second scandal in recent years as Annie Dookhan served three years in prison for falsifying and “drylabbing” drug test results. This caused the Massachusetts Supreme County to dismiss 22,000 of her cases.
Augenstein provided a succinct and well-written article that summarized the facts of this case. I think that the article did a good job of introducing the reader to this scandal, but the author did no delve very deep into the actual criminal case or the subject of lab contamination. The dates of the convictions for both Farak and Dookhan were not clear and it’s confusing to read a lot of 2014 dates in a recent 2018 article.

Never Solved, a College Dorm Fire Has Become One Man's Obsession

Bronxville School
April 18th, 2017
In 1967 a fire at Cornell University killed 9 people. No one was ever charged for the crime but now with new forensic evidence an amteur investigator thinks he knows who set the fire. The students in the dorm woke up and thought they smelled a barbecue but to their surprise they were right in the middle of a fire. The smoke made it nearly impossible for the students to escape but that didn’t stop them from trying many scrambling to escape one even hobbling on crutches. Students detaches the window screens in order to crawl out of the windows. As students gathered at the nearby sorority the mood darkened as they learned the truth about what had happened. Eight Students had died and one teacher the heroic Mr. Finch. Many students were forced to reschedule their remaining days and many were still scared that the killer was targeting them but they could never figure out exactly who the killer was.
` But in 2013 William Fogle decided to investigate it into more depth. The Phud program he conceived didn’t work as planned though. Continuing his research with not much results was very difficult for him but he trudged along. He found a breakthrough when someone told him about a student who had come under suspicion for odd behavior. But the student couldn’t be found. Eventually he found a teanager who had been killed in New mexico. His theory was that the student had killed him and taken the identity. He soon found the identity of the person he was looking for through many different means. Although he can’t prove that this man did it he is almost positive that he did.

I found this article to be very interesting because it shows you that how investigating something as simple as a fire can lead to new and more mysteries and if you don’t give up you can find the killer and maybe even find more crimes that had been committed.

“They Died Near the Border. Art Students Hope to Bring Them Back.” By, Patricia Leigh Brown

This article tells the story of the bodies of eight individuals found in the emptiness of the Arizona desert, assumed to have died during their journey to escape across the Mexico Border. According to the Pima County medical examiner’s office the individuals died from; “Heat stroke, exposure to hot environment. Hyperthermia due to exposure to the elements. Dehydration, hypotension and hyperthermia due to environmental exposure to heat in desert” as well as a number of other causes. The traditional tools medical examiners usually use to identify human remains, such as DNA and dental comparisons were inconclusive. The mysterious identities of the eight men remained unknown, which struck the curiosity of art students at The New York Academy of Art, who are working to create facial constructions of the individuals in order to identify them. The remains were left in the students hands at a facial reconstruction workshop, taught by Joe Mullins, a forensic artist with the National Center for Missing and Exploited Children. The process to create such a project is completed as followed; “reconstructing a face with scientific accuracy involves rebuilding the muscles and soft tissue layer by layer, using strips of clay. Then the students use cut plastic straws placed on the clay to mark tissue depths, which are based on researchers’ averages for ages, genders and cultural backgrounds.” Since 2001, thousands of bodies found in the Pima County alone remain unidentified, the harsh environment leaves traveling individuals lost to the desert.
The work of these students is heroic, in hopes that their efforts in recreating the faces of these individuals can reunite with their families to bring them closure after the deaths. It is an incredibly strenuous and creative process that required the unique focus of these “visual creators.” If the students are successful, they could be impacting the future of traditional protocol for medical examiners when identifying human remains. It is not uncommon for the DNA and dental comparisons to lack any conclusions, so to have this art as a backup to those methods would be life changings.

This article was extremely interesting not only because I find both Art and Forensic studies fascinating, but because it is a unique combination of two completely different work forces. The author, Patricia Leigh Brown, did an excellent job with the flow of the article and included a good use of facts to support her story. I found every aspect of her writing to be crucial to the article and have almost no critiques. The one aspect I felt could have been interesting is if Patricia was able to include the identities of the art students working on this project, it would be very interesting to hear their point of view on the investigation.

Long Island Woman Who Vanished 50 Years Ago Dug up From Cop Boyfriend's Basement.

www.forensicmag.com/news/2018/04/long-island- woman-who- vanished-50- years-ago- dug-cop-
boyfriends-basement.

The article this week that I chose to read “Long Island Woman Who Vanished 50 Years
Ago Dug up From Cop Boyfriend’s Basement” written by Seth Augustine by Forensics
Magazine. In 1966 about 50 years ago, Louise Pietrewicz went to her bank and took out all of
the money out of her account and disappeared. She left behind the purse and was trying to get
out of a terrible marriage, The Cold Case sitting in a file room for 51 years until a local tip came
up from a woman who was having affair with Louise&#39;s husband. The tip ended up leaving
investigators to use sonar waves in the ground where they found a skull. “Cold cases are always,
always in play. We’re always looking at information we obtain.” Police had tried to dig up the
residence in 2013, but did not find anything. After the investigators dug up the skeleton, forensic
scientist were able to connect the DNA to Louise. The tip made by The Mistress of her husband
would end up helping the case, Louise&#39;s husband died in 1982 who was the lead suspect.

This is a absolutely reflection of how modern forensic science has helped the past , cold
cases like this that have been sitting in a file cabinet for 51 years are finally being able to be

solved because of technology today. Louise is murder was found with top of the line sonar
equipment. Showing there are many ways to use modern technology to help the past . More and
more cases like these are going to be solved in modern day, finally after many years some
justice can be served.

The author did a good job with the article, the one thing to critique him about is his
information used from the case. He talks about how she disappeared and how the body was
found but other things have been left out. The article was very informative but I would have
appreciated more info about the case.

They Died Near the Border. Art Students Hope to Bring Them Back - Zach Zucker

Zach Zucker
Mr. Ippilotio

Brown, Patricia Leigh. “They Died Near the Border. Art Students Hope to Bring Them Back.”
After reading Patricia Leigh Brown’s article “They Died on the Border” the main impression that I took away from this article was that I was very impressed with the author’s work. Thus because I liked this work so much with the work that the author put into it, I found this review that she made to be very interesting to read for my latest current event. Therefore this article emphasizes the forensic reconstruction particularly the face with scientific accuracy. She states this when she also highlights its purpose because when you do this it helps in cases where decomposition has rendered a face that is found to be unrecognisable. She states in her article that because people do not spend enough time on the matter, the matter itself has become a major issue with immigrants near the southern US- Mexico border. Although the number of people attempting to enter has decreased the number of people who die near the border has increased with what’s happened to our country in the last year with the madness that has occurred with Donald Trump being the United States President and all his problematic policies.
The main purpose is to ensure that these people in search of better lives don't lose their identities in the process. The process that recreating faces has is that it can be helpful for identifying people's DNAs. It can be used domestically with decade old homicides and abroad with soldier identification. Therefore from this article that is very well done, I think it would be interesting to study history and not only see paintings to people but have a realistic feel of what they actually looked like because you don’t know what a person is perceived like unless you have a clear photo that resembles there features: such as Julius Caesar and King Henry the third. Therefore, Brown points out the fact that our new technology saves people from falling through generation is  something that I find very interesting and there should further advances in forensics and in other fields which allow people even after death to be noticed and give closure.

Though I enjoyed reading Mrs. Brown’s review on the matter, and though I believe that the article was very well written, it was not perfect because there were more questions left than answered which were covered within her article. Therefore while she will not here my view, the one thing that I believe the author could work  on in the future would be to see the author add a personal case and opinion to see if this matter could be really used. I say this because the article was rather broad and didn’t give me the reader much victory since it didn’t discuss how this method has lead to people being identified or how it gave closure to families because it only vaguely summarizes it. The article seemed to talk about the same thing a lot when I wished it gave better description and engaged the reader more. Although the topic was interesting the way the author presented the results was a little boring and left me wanting more detail. I chose this article because it spoke to me personally with the many problematic issues that are going around our world right now as well as the fact that I love the New York Times. I enjoyed reading this article and I find this matter on the subject very interesting to read.

He was a groundskeeper at the White Sox’s stadium at 25 before being convicted of rape murder of a young women. After 23 years behind bars new DNA evidence has come to light which has cleared him of the rape and murder. The evidence which came up was allegations of police misconduct and semen samples collected from the body and clothing of the victim. When the DNA from the semen did not match Mr. Coleman's DNA, he was released
This article does contain relevance to society today. The city of Chicago is going back and is willing to overturn past convictions and make sure they get it right with the new technology being used to clear innocent people.

This article was well written and have a good insight to the process behind proving innocence in old cases where new technology is being used.
