The Mark of a Serial Killer, Momentos of Murder

In 1990, a serial killer terrorizes the University of Florida's campus, killing 5 students in under 4 days. 'The Gainesville Ripper' leaves behind a bizarre crime scene where all the victims have been stabbed but the females have been posed like dolls

The 'Last Call Killer" hunted his victims openly in piano bars but no one suspected he could be hiding in plain sight, working as a local nurse.

After several women are found strangled along the highways of Sacramento, a survivor leads police to the murderer, who posed as a good samaritan to poach potential victims.

After police catch the Hillside Stranglers they realize they still have another serial killer running rampant in Los Angeles. This one tortures and toys with his model victims while keeping pieces of their jewelry as he snaps their last photo ever.

Texas police search for a killer who is riding the rails and leaving a literal trail of breadcrumbs after eating at victims' tables. The hunt goes national when more murders are linked.
