A 47-year-old Wisconsin man charged with stalking a woman he dated briefly more than a decade ago kept human skulls, skeletal remains in a glass casket, poisons, and serial killer memorabilia inside his rural home, and investigators are now working to determine whether any of the remains are connected to other crimes.
Benjamin Larson of Fond du Lac County faces up to 42 months in prison after police searched his home on August 14 and found what court documents describe as a collection that reads like an inventory from a horror film. Five human skulls and one partial skull sat on his bedroom shelves. A human jawbone rested on his dresser. A full set of skeletal remains lay inside a glass casket. Another skull was mounted in a separate glass display case.
The stalking charge stems from a woman's report to police that Larson had pursued her obsessively since June 2013, a span of roughly 13 years, after she agreed to let him make a "body cast" of her at his house in Madison, Wisconsin. The two dated only a handful of times over about two months before she ended the relationship, the New York Post reported, citing court documents.
The accuser told police she cut off contact after Larson called her and said he was "suicidal with a gun to his head." She moved to Canada without giving him her address because, she told investigators, she "just wanted to disappear."
Disappearing did not work. In 2015, Larson sent her an email revealing he had tattooed her initials on his body so she could "never go away." In the same message, he wrote:
"I simply don't let go, and I don't forget. I still retain every single word you wrote to me. Everything you gave to me."
As recently as December 2025, Larson mailed her a card that read "Season's Creeping." Court documents describe him writing about himself dressed in "all black, with black gloves and a black mask," watching his former girlfriend's movements from his car, "creeping around in the dark."
A 25-page, handwritten portfolio of notes addressed to and about the accuser was found in his home. One passage laid bare the fixation in Larson's own words:
"I am furious at the thought of her with him, and that they have a child... That he experiences her wonderfully erotic mind and I sit in my basement corner and rot and seethe."
What police found beyond the stalking evidence turned the case into something far more disturbing. Larson's basement contained 10 binders devoted to Edward Gein, the serial killer known as the Butcher of Plainfield. Items described in court documents as taken from Gein's home and grave were allegedly among Larson's possessions, though their authenticity has not been confirmed.
A sign in the basement indicated that a nearby jar held a piece of John Wayne Gacy's brain. Officers also recovered bullets described as matching the type used by the Zodiac Killer, various types of poison, and numerous framed images of nude women.
Behind a locked bedroom door, investigators found a painting of a naked woman whose appearance was consistent with the accuser's, hung above a large, lifelike silicone sex doll on a bed. Handwritten notes addressed to the accuser surrounded the display.
Local anthropologists are now working with the Fond du Lac County Sheriff's Office to determine whether the human remains are authentic and whether any are connected to criminal activity. Many of the remains are assumed to date to the ancient Native American period, though that assessment has not been finalized. The sheriff's office posted about the investigation on Facebook, and Fox 11 reported on the forensic examination.
Larson is scheduled to appear in court on September 11. Court documents do not indicate whether he has entered a plea, and it remains unclear whether he is currently in custody. The stalking charge carries a maximum sentence of 42 months.
Several questions remain unanswered. Investigators have not said what specific types of poison were found or whether the purported Gacy brain specimen is being tested. The provenance of the items linked to Gein's home and grave has not been publicly verified. And the critical question, whether any of the human skulls and bones are connected to unsolved crimes rather than historical artifacts, is still under examination.
The accuser in this case did everything a reasonable person would do. She ended the relationship. She cut off contact. She left the country. She did not share her address. And for more than a decade, none of it was enough to stop the letters, the emails, and the cards from arriving.
Larson faces a maximum of 42 months, three and a half years, on the stalking charge. That is the ceiling, not the floor. For a woman who spent 13 years trying to disappear, it is worth asking whether a system that lets this conduct persist for over a decade before producing a single charge is calibrated to protect victims or to wait until something worse happens.
When someone keeps human skulls on a shelf, pens 25 pages of obsessive notes about a woman who fled the country, and describes himself prowling in the dark wearing a mask, the law ought to move faster than the stalker does.
