Recently, a pioneering scientist from Britain by the name of Dr. John Bond offered to take on an unsolved case from America.  The victim, Marianne Wilkinson, was 69 years old when she answered the door at 7:30 pm in her house in North Richland Hills, Texas on December 9, 2007.  Unfortunately, she was immediately shot three or four times, and the assailant fled.  Recently, investigators have come to believe that she was not the intended murder victim, and that the intended victim lived next door.  As a result, the murder case has made little progress, thus raising the need for outside help.  Dr. Bond has developed a scientific process by which fingerprints on bullets could be visualized, even if the bullet has been wiped clean, as he developed a technique that can detect wiped fingerprints on nearly all metals.  He has even been approached by military personnel in Afghanistan to discuss potential use of the technique to find prints on roadside bombs.  Recently, a gun was found that is believed to be the one that shot Marianne, for her murder is considered a case of a paid assassin making a mistake.  Thus, Dr. Bond has been brought in to try and identify the persons who last used  the gun, and try to bring Marianne Wilkinson's murderer to justice.
