Karen Slattery Wiki, Biography

Karen Slattery was just 14 years old when she was brutally murdered while babysitting for William and Carolyn Helm in Delray Beach, Florida. An intruder entered the Helm home and stabbed Karen multiple times before sexually assaulting her body and leaving the teen to die.

Although detectives couldn’t find much about who killed the teen and the case went cold, they did make some revelations that helped them track down the killer. They identified Duane Owens as the intruder and convicted him of murdering Karen and another woman, who was later murdered in a similar fashion.

The murder of Karen Slattery will be detailed in Investigation Discovery’s Your Worst Nightmare true crime series on January 19, 2023 at 7 p.m. Titled He’s Out There, the synopsis for the episode reads:

“Florida teen Karen Slattery is brutally murdered while babysitting a neighbor’s children; the violent intruder disappears without a trace, and the case remains unsolved.”

Karen Slattery was stabbed 18 times by an intruder, Duane Owen

As mentioned above, Karen was babysitting Carolyn and William Helm’s children on March 2, 1984, when an intruder entered the home. He stabbed her 18 times throughout her body and raped her unconscious body before leaving her to die.

When the couple returned home after midnight, they found Karen’s belongings scattered around the house and a large pool of blood in the kitchen. Her blood was traceable to her bedroom, and the couple immediately called the police, who found Karen’s body in the bedroom.

When the police arrived at the Helm home, they noticed that Karen had been stabbed multiple times all over her body. Upon further investigation, they discovered that she was stabbed 18 times in all: eight times in the back, six times in the neck, and four stab wounds cutting her throat.

They also found out that although Slattery was stabbed many times, she was alive but unconscious and the killer dragged her body from the kitchen to the bedroom. They revealed that she too had been raped while she was unconscious. The teenager died due to excessive blood loss after all the stabbings of her.

An unrelated confession led investigators to Slattery’s killer.

Although investigators did their best to track down the killer, the investigation soon went cold as they found no evidence leading to the killer. However, a few months after Karen’s death, it was a confession that made it easy for investigators to zero in on one person.

Duane Eugene Owen was arrested on Mary 29, 1984 in connection with an unrelated robbery case. On the same day, a murder had also taken place and investigators had a hunch that he had a connection to Owen and questioned him about it.

Although he denied it at the time, a month later, police found an inked print at the Helm House, where Karen was murdered. By comparing it to Owen’s print, they found a match and arrested him.

Owen had also previously told police that he was ready to make a confession if they found evidence. Since the footprint counted as evidence, Owen had no choice but to confess to the murder of Karen Slattery and Georgianna Worden, 38, the woman found murdered in May 1984.

Duane Owen was charged with first degree murder and convicted in both cases separately.

As mentioned above, Your Worst Nightmare episode will air on January 19, 2023 at 7 p.m.
