The 1980s: The Deadliest Decade

The son of a notorious serial killer becomes an acclaimed criminal psychologist who uses his unique insight into how killers think to help the NYPD.

Candy and Pat Montgomery and Betty and Allan Gore — two churchgoing couples — enjoy their small town Texas life... until an extramarital affair leads somebody to pick up an axe.

From Executive Producer Dick Wolf, this true crime investigative series follows veteran prosecutor Kelly Siegler, and her rotating team of seasoned detectives, as they travel to small towns across the country and help local law-enforcement agencies dig into unsolved homicide cases that have lingered for years without answers or justice for the victims due to lack of funding and proper forensic technology.
