The importance of processing a sexual assault crime scene properly cannot be emphasized enough. Sexual assault cases are actually two crime scenes—one is the location of the occurrence and the other is the body of the victim. These scenes require not only a comprehensive crime scene search, but also swift examination and questioning of the victim. AMU professor Dena Weiss, a 17-year crime scene investigator (CSI), explains the various pieces of evidence a CSI is searching for and collecting as well as how police officers can help preserve key evidence in sexual assault cases.
For the past five years, forensic scientists have been taking advantage of their ability to collect Touch DNA, small samples of DNA from evidence that has been handled by suspects. However, new research has found that bacteria may be the next generation of forensic evidence used in police investigations. Learn more about key research studies focused on the benefits and feasibility of using bacterial fingerprints as evidence.

The first officer at the scene walks a fine line regarding their actions at a crime scene. Upon arrival, crime scene investigators (CSI’s) would like to be provided a general idea of what occurred, but at the same time they do not want an officer to disrupt the crime scene.
