In episode two, Just Science sat down with Erin Sims, Forensic Lab Manager at the Lincoln, Nebraska Police Department, about bloodstain pattern evidence in forensic investigations.

Not all crime scenes will have bloodstains. But when they are present, analysts can use them to help determine the types of activities or mechanisms that produced them. Erin Sims believes that bloodstain patterns can tell the unknown story behind a crime. Listen along as she discusses the application of bloodstain pattern analysis and how it fits into the larger puzzle of crime scene investigation in this episode of Just Science.
