A Wisconsin man is accused of stalking a woman for 13 years and was found with human skulls and a jar claiming to contain part of serial killer John Wayne Gacy’s brain in his home.
Another journal entry described Larson allegedly driving to the victim’s home in Madison while wearing black clothes, gloves and a mask. He wrote about watching her home with a machete, recording her license plate and taking three bags of her garbage. She ended the relationship after he called saying he was “suicidal with a gun to his head.
Detectives executed a search warrant at Larson’s home on August 14, 2026, according to WBAY .
In the basement, they found a grave rubbing of serial killer Edward Gein, 10 binders labeled “Edward Gein Book,” items taken from Gein’s grave, and cartridges similar to those used by the Zodiac Killer. Per the Fond du Lac County Sheriff’s Office, cited by Fox11, the stalking allegedly began in June 2013 when she let Larson make a “body cast” of her at his home. The sheriff’s office said it is working with a forensic anthropologist to determine whether the remains found in Larson’s home are authentic, and whether they are modern-era remains or archaeological Native American remains.
In November 2025, he allegedly sent a card saying, “I’m not sure if I need to try calling, or just knock on your door someday. The next month, she got a card at her home address, which she’d never given him, mentioning her husband and child by name.
