Woman who dated serial killer later realized she was on drugs

Bruce Lindahl lived in a normally quiet suburb of Chicago and had many secrets, including one from a woman he was dating.

Sherry Hopson had no idea that the man she was dating was a serial killer, but during their time together, she noticed that Lindahl was behaving in surprising ways.

Hopson tells the story of her encounters with Lindahl in the latest episode of People Magazine investigates: Surviving a serial killer.

Lindahl, the killer at the center of the episode “Surviving the Handsome Devil,” is known to have killed at least four people, although the actual number could be much higher. Lindahl, who died in 1981 after murdering an 18-year-old man, also committed several sexual assaults.

One of the first warning signs Hopson noticed during her time with Lindahl was his anger, which she talks about in a clip from the show she shared with PEOPLE.

“Bruce would get angry very quickly if I said no,” Hopson recalls. “He had a hot temper, a very, very quick temper.”

Hopson recounts an incident in which she found another woman's earring in Lindahl's car and confronted him about it.

“He took it out of my hand and said, 'That's my sister's earring,'” Hopson says. “And he rolled down the window and threw it out.”

Hopson was surprised that Lindahl threw away an earring that supposedly belonged to his sister and replied that his sister “doesn't need it.”

There were other alarming signs.

“Sexually, he was a little rough,” says Hopson. “There were times when I would wake up and not remember going to sleep. And I would wake up and be late for work and a couple of times I would be really groggy and think, 'Oh my God, I can't wake up.'”

Lindahl replied that she didn't need to worry, the effects would wear off.

“When I look back now, I think: That guy gave me drugs and I didn't know it,” says Hopson.
