In February 1988, a 29-year-old John Duffy was on trial for the rape and murder of three women. He was a terrifying figure, and infamous across London. His arrest brought an end to a horrific four-year crime spree across the British capital, but he was only a half a murderous duo. Duffy refused to give up the name of his accomplice, and without any leads, the police have no choice but to wait. It would be another 15 years before the other man was found guilty for his part in the heinous crimes. Over a decade later, the imprisoned Duffy has had enough, and tells investigators he will testify against his former accomplice, and friend, David Mulcahy.

In this last episode of season five, we'll examine Floridian serial killer Bobby Joe Long... 



1984. Tampa, Florida. 



A 17-year-old girl named Lisa was on her way home from work, when she was abducted from the side of the road. For the next 26 hours, she was subjected to a terrifying imprisonment by a sadistic sexual predator, who had already killed several young girls. But, unlike the other victims, Lisa was the only one to survive. 



As bodies were being discovered every other week, Floridian authorities realized a serial killer was on the loose. Investigators didn't know it yet, but the killer was a 31-year-old army veteran and divorced father of two hiding in plain sight. And over the course of eight months, ten women would die by his hands in the Tampa area.

S5 Ep13: Bobby Joe Long

September 22nd, 1991. Guilford, Connecticut. Early that evening, a mysterious man visited the home of Christine Brendel and delivered some shocking news – her brother Ernest and his family had been kidnapped, and were being held for ransom by the Mafia. It turned out the man at the door, 42-year-old Christopher Hightower, was a pathological liar and a killer. He claimed he needed $75,000 to release the family, but in reality, they had already met their fate. Most shocking of all was Hightower's methods. He killed Ernest – who was a friend of his – with a crossbow, strangled his wife Alice, and then drugged their eight-year-old daughter Emily, and dumped her in a shallow grave. But in court he continued his lies, claiming he saw the mob carry out the killings.

S5 Ep11: Vincent Tabak

On February 24th, 1986, police in Talladega, Alabama forced their way inside the home of 24-year-old mother and student Sherri Weathers. When she had not shown up for classes in over a week, police were sent to do a wellness check. And soon the reason for her absence became very clear.  



Sherri and her two young children had been strangled to death, and their killer had piled them on top of each other in the shape of a cross. The killer was a 31-year-old artist and seasoned criminal, and his macabre masterpiece was far from complete. Two more bodies were discovered, and the killer had slipped away without a trace. With no clue as to where he went, police began the long and grueling search to find him, before he struck again.

November 13th, 1977. Los Angeles, California. Young students, Dolores and Sonja were on their way home from a day out shopping, when two police officers stopped them for questioning.

Their killers were two cousins, Angelo Buono and Kenneth Bianchi. The partners in crime went on a killing spree, murdering 10 young women in just four months. Many were dumped on hillsides across LA – locations that would lead the killers to earn their infamous moniker.
