If the crime involves a murder, the body itself holds many clues. Medical examiners can give important information about how the victim died. They study wounds and chemical tests to find out if the victim died accidentally or not. They can tell if a wound was created by the victim or by another person. And, they can discover the time of death to see if it matches information given by suspects and witnesses.

STEVE EMBER: Visitors to the Museum of Crime and Punishment can learn more about blood and its importance in an investigation. They can attend a Crime Scene Investigation workshop. During these events, a trained expert talks to museum visitors and leads an experiment. We attended one that was taught by a graduate student from George Washington University’s Forensic Science Department.
For example, she discussed how investigators can learn a great deal from the shape of the blood drops found at a crime scene. A circular blood drop could mean the blood fell directly downward. But blood drops with long tails can tell a great deal about the direction, speed and angle of the blood’s starting point.
LARISSA: “That tail tells you the direction the blood was travelling. So if your tail is pointing that way, which direction was your blood going?”
BARBARA KLEIN: This information can show what kind of weapon was used in a murder. And it can show from what position the murderer killed a victim.
