After the Golden State Killer's arrest in 2018, dozens of rape victims learned their assaults weren't isolated incidents but the work of a serial killer. Read how many survivors bonded through mutual trauma.

We spoke with Joni Johnston, a forensic psychologist, to explore the ancient legacy of poisonings, the psychological profile of a homicidal poisoner and common myths and misconceptions about those who poison.

Without a body, proving that someone has committed murder is difficult but not impossible. More than 500 no-body murder trials have been held in the United States, with a conviction rate higher than that of all murder trials.

In today's world, homicide detectives are expected to be jacks-of-all-trades: equally adept at chasing outlaws and identifying DNA evidence at the scene of the crime.

You may have heard about body farms, the research facilities where people donate dead bodies for scholarly research. But have you ever wondered what goes on in these places? What exactly are scientists doing with all these donated bodies? What mysteries are they trying to solve, and why?

When new evidence arises, or new technology becomes available, investigators may need to take a second look at a corpse.

Genealogical DNA databases are helping solve more cold cases. We explore why that could be problematic.

Since the Golden State Killer suspect was arrested after being tracked down via a DNA database, more crimes are being solved that way.
