On April 13, 2012, the Pittsburgh Post-Gazette covered the trial of Jordan Brown, a juvenile charged with criminal homicide in the death of his father’s pregnant fiancée ( http://www.post-gazette.com/stories/local/region/jordan-brown-decision-expected-631177/). The victim suffered a fatal gunshot wound to the head. In charging Mr. Brown, who was 11 years old at the time of the crime, police needed to know if there was evidence of gunshot residue on his clothing. Ms. Elana Somple, an expert witness and Manager of the Forensic Science Department at RJ Lee Group laboratory in Monroeville, Pa., was contracted by Pennsylvania State Police investigators to determine if there was evidence of gunshot residue on clothing samples taken from the suspect. Her testimony at the trial was that some of the defendant’s clothing tested positive for gunshot residue, which indicated that the young man had fired a gun or was in proximity when one was fired. Mr. Brown, who is now 14 years old, was found delinquent, the juvenile court equivalent of a guilty verdict.
