A Wisconsin man, Benjamin C. Larson, 47, faces charges of stalking a woman for over a decade, with authorities discovering human skulls and a jar containing part of John Wayne Gacy’s brain at his residence.
Why it matters: This case highlights the serious nature of stalking and the alarming behavior exhibited by Larson, which escalated over 13 years.
Larson is charged with one count of stalking after allegedly harassing the victim since their brief relationship in 2013.
The victim reported Larson’s obsessive behavior, including unsolicited communications and harassment through professional channels.
Authorities found disturbing items in Larson's home that raise concerns about his mental state and intentions.
Driving the news: The victim contacted Madison Police on July 31, 2026, detailing her experiences with Larson, who she dated for nearly two months in 2013 before ending the relationship due to his concerning behavior.
After their breakup, the victim moved to Canada, but Larson continued to find her, sending unsolicited letters and emails.
In November 2025, Larson sent a card stating he would “continue to try contacting” her, expressing uncertainty about how to reach her.
By December 2025, he sent another card to her home, referencing her husband and child by name, indicating he was nearby.
State of play: On August 14, 2026, detectives executed a search warrant at Larson’s home, where they uncovered a disturbing collection of items.
Investigators found 10 binders labeled "Edward Gein Book," items from Gein’s grave, and cartridges similar to those used by the notorious serial killer, the Zodiak Killer.
Among the finds were six human skulls, a partial skull, a human jawbone, and skeletal remains encased in glass.
A mummy labeled "Princes Taheb 1600 BC" was also discovered, along with vials labeled with dangerous poisons like arsenic and cyanide.
The big picture: Larson's obsession with the victim and his collection of macabre items raise serious questions about his mental health and the potential danger he poses.
The victim described their relationship as intense and stated Larson had exhibited obsessive behavior, including a suicidal call where he claimed to have a gun.
In 2015, Larson emailed the victim stating he had tattooed "their symbol" and her initials on himself, indicating he still held onto mementos from their relationship.
He expressed his feelings in writing, saying, "My will to care about you is just too strong. I simply don't let go, and I don't forget."
What they're saying: Law enforcement officials are taking the situation seriously, noting the psychological implications of Larson's actions.
The sheriff’s office is collaborating with a forensic anthropologist to assess the authenticity and origin of the skeletal remains found in Larson's home.
Initial examinations suggest that many remains may be ancient Native American, but specialized forensic testing is required for confirmation.
Larson's defense claims his communication with the victim was civil, attributing the licensing board complaints to suggestions from his therapist.
By the numbers: If convicted, Larson faces severe penalties for his actions.
He could receive up to three years and six months in prison and a fine of up to $10,000.
Larson posted a cash bond of $15,000 following his arrest.
He is scheduled to return to court on September 11, 2026, for a hearing related to the stalking charge.
What's next: The investigation continues as authorities work to determine the full extent of Larson's actions and the origins of the remains found in his home.
Forensic testing will clarify whether the skeletal remains are modern or archaeological in nature.
Law enforcement is likely to pursue additional charges based on the findings from the investigation and forensic analysis.
The victim's safety remains a priority as authorities explore protective measures and resources available to her.
