When recovering biological evidence from a crime scene it must be handled with extreme caution, as it is highly perishable. This article discusses the recovery of hair and semen from bedding and clothing left at the scene after a sexual assault. After an initial search of the scene—done to locate the evidence—the evidence should be well photographed and videotaped. Also, it should be noted that investigators must wear protective clothing—at all times, no matter what evidence is being collected—changing them every time new evidence is collected, as well as using tools, such as tweezers and so on.

A miraculous discovery was made yesterday, as three girls who had been kidnapped and held for nearly a decade were all found alive in a house in Cleveland, OH. Amanda Berry (left) disappeared at age 16 on April 21, 2003, on her way home from her job at Burger King. Gina DeJesus (right) vanished at age 14 on her way home from school, about a year after Berry’s disappearance. Michelle Knight was also found in the house; she had disappeared in 2002 at age 20 and is 32 now. They were found just a few miles from where they had vanished.
