Jeffrey Dahmer’s dad was left a ‘nervous wreck’ after a woman threw her used underwear at his home

According to man's caretaker, Jeb, 34, the woman also yelled: “I love you Lionel.”

The outlet also reported another incident, when the father was targeted by a man who approached him in a ‘hostile and aggressive' manner, which led his caretaker to install ‘No Trespassing' signs on Lionel’s property.

Jeb has also now started carrying a gun to protect his client.

“It’s people like that that we’re trying not to have here, that’s why I put up no trespassing and private property signs.

"Lionel’s 86 and here’s this 20-year-old lady throwing her underwear at him. It's just like, stop.”

In the series, Lionel is played by the actor Richard Jenkins, who helps illustrate the fractured and tattered relationship with his serial killer son.

In real life, Lionel acquired his PhD in chemistry and worked as a research chemist when Jeffrey was a young child.

The two would frequently (as depicted in the show) collect and dissect animal remains, including roadkill, as his father believed his son was interested in studying animal autonomy.

He is also said to be angry that the streaming service did not seek permission to use audio footage recorded by his son's lawyers for the separate docuseries Conversations with a Killer: The Jeffrey Dahmer Tapes.

Rita Isbell, whose brother was murdered by Dahmer, said watching the show 'felt like reliving it all over again' and said it was 'sad that they're just making money off this tragedy'.

"They didn't ask me anything. They just did it. But I'm not money hungry, and that's what this show is about, Netflix trying to get paid."

Shirley Hughes, mother of Dahmer victim Tony Hughes, said she had been heartbroken to see costumes relating to the serial killer appearing on the site.
