"How Microscopic Algae Are Helping Forensic Teams Catch Criminal." Forensic Magazine. N.p., n.d. Web. 20 Apr. 2016.
This article talks about how deserted fields, dark forests, murky rivers, concrete jungles, and environments can leave traces of physical evidence on a criminal. Ever since the late 1800, this principle has been well known to crime scene investigations. However, unfortunately, the most reliable pieces of evidence can be difficult to analyze.
For example, Microscopic algae, such as diatoms, can be picked up from virtually anywhere there is water – including seas, lakes, soils, some domestic water supplies and even moist surfaces such as exposed rocks. While diatoms traditionally have been used to diagnose death by drowning, research is unravelling their huge potential for use as trace evidence in a range of forensic investigations. They appear golden brown to the naked eye. They are composed of silica- recently found to be the strongest natural material on the planet.
Overall, this article was interesting and the information was all new to me. However, it would have been better if the Author of this article included more information on specific crime scene cases that have been solved due to these pieces of evidence.

I think this review presented very well that physical evidence from the environment can be found on a criminal.The review explained well why the evidence can be hard to analyze. Also the review explained well what diatoms are.
Overall this review was very well done. To improve this review I would add more quotes from the article. Also I would give more example of Physical evidence from the environment.
I was surprised that environmental physical evidence such as microscopic algae can be further investigated to find trace evidence.
