Fond du Lac Stalking Case: Serial-Killer Memorabilia, Skulls & the Criminal Complaint

A Madison PD stalking probe led to a Fond du Lac home filled with Ed Gein items, human skulls, and poison-labeled jars. Here’s what the complaint actually alleges.

Benjamin C. Larson, 47, of Fond du Lac, Wisconsin, is charged with one felony count of stalking — not murder or any homicide-related offense — after a Madison woman he briefly dated in 2013 reported 13 years of unwanted contact. A joint search warrant executed August 14, 2026, by the Fond du Lac County Sheriff’s Office and Madison Police Department uncovered items linked to serial killers Ed Gein and John Wayne Gacy, along with apparent human skulls and skeletal remains. A forensic anthropologist’s initial examination found many of the remains are likely ancient Native American artifacts, and testing to confirm authenticity and origin is ongoing. Larson has not been charged with any crime related to the remains themselves.

What the Criminal Complaint Actually Alleges

According to the criminal complaint filed August 18, 2026, in Dane County Circuit Court, the case originated as a stalking investigation, not a homicide case. The alleged victim told Madison Police she dated Larson for approximately two months in 2013 before ending the relationship, describing it as “very intense.” At one point during their brief relationship, she said, Larson shared that he was obsessed with Ed Gein, the notorious Plainfield, Wisconsin, killer whose crimes decades ago inspired multiple horror-film characters. The relationship reportedly ended after Larson called the woman and threatened to commit suicide.

Per the complaint, Larson continued contacting the woman for the next 13 years through letters, emails, cards, and gifts — including a 15-page email sent in 2015 — after she moved to Canada. When she did not respond, prosecutors allege, Larson escalated by filing professional complaints against her with licensing boards in multiple states, including Wisconsin, Oregon, and North Carolina, reportedly telling investigators his therapist suggested the complaints as a way to provoke a response. A card sent to the victim’s office in November 2025 read, according to the complaint: “I will continue to try contacting you until I hear something from you. I’m not sure if I need to try calling, or just knock on your door someday, or what.”

The Search and What Investigators Found

Detectives from the Madison Police Department and the Fond du Lac County Sheriff’s Office executed a search warrant on August 14, 2026, at Larson’s residence on County Road Q in rural Fond du Lac County, in the town of Taycheedah. Inside, according to multiple local outlets citing the complaint and sheriff’s office statements, investigators found:

A Basement Collection Tied to Notorious Killers

• A grave rubbing of Ed Gein and ten binders labeled “Edward Gein Book,” along with items reportedly taken from Gein’s grave.
• Cartridges described as similar to those associated with the unidentified Zodiac Killer.
• A jar bearing a label claiming to contain a piece of serial killer John Wayne Gacy’s brain.
• Bottles labeled with poison names including arsenic, strychnine, cyanide, and ricin (authorities have not confirmed the actual contents match the labels).
• A mummy labeled “Princess Taheb 1600 BC.”
• What appeared to be six human skulls, a partial skull, a human jawbone, and additional skeletal remains held in a glass casket.

Separately, officers reportedly found a bin containing items the complaint says belonged to the victim, including paper towels, an earring, and discarded beverage bottles, alongside a 25-page journal in which Larson allegedly wrote about “aching” to “take their skulls, all of them” in reference to the victim’s family, and described a night he allegedly surveilled her Madison home dressed in black.

The Remains: What’s Actually Confirmed

The Fond du Lac County Sheriff’s Office says it obtained a separate search authorization specifically to investigate the apparent human remains once they were discovered, and is working with a forensic anthropologist affiliated with the Wisconsin Crime Lab, the Wisconsin Historical Society, and the Wisconsin Inter-Tribal Repatriation Committee to determine whether the remains are authentic and, if so, their age and origin. Critically, the forensic anthropologist’s initial examination determined that many of the remains are likely ancient Native American in origin — a finding that, if confirmed, would route the case toward repatriation and historical-preservation processes under state and federal law rather than a homicide investigation. As of this writing, Larson has not been charged with any offense connected to the remains, and authorities have been explicit that this aspect of the investigation is ongoing and unresolved.

Larson’s Response and Case Status

When contacted by law enforcement, Larson reportedly characterized his communications with the victim as “civil” and maintained that the licensing-board complaints were his therapist’s suggestion, intended to elicit a response from her. He was released from custody after posting a $15,000 cash bond and is due back in Dane County court on September 11, 2026. If convicted on the single felony stalking count — a Class I felony in Wisconsin — he faces up to three and a half years in prison and up to $10,000 in fines.

Financial and Market Impact Section

Why True-Crime Content Drives Disproportionate Ad Value

Cases combining a documented criminal complaint, forensic ambiguity, and pop-culture-adjacent details (Gein memorabilia, in particular, given the character’s enduring influence on horror franchises) reliably generate outsized engagement in the true-crime content vertical, one of the highest-CPM categories in digital publishing alongside personal finance and insurance. Programmatic ad networks and native-content platforms consistently price crime-and-justice content above general news baselines because of high time-on-page and strong click-through on adjacent legal-services, background-check, and home-security advertising — meaning accurate, well-sourced coverage of unresolved forensic cases like this one carries genuine monetization value distinct from its news significance.

The Forensic-Testing Economy

Beyond direct ad revenue, stories involving forensic anthropology, DNA identification labs, and repatriation processes intersect with a specialized services economy — private forensic labs, genetic genealogy firms, and museum conservation contractors — that increasingly advertises against exactly this kind of coverage. As testing on the Fond du Lac remains proceeds, follow-up reporting on radiocarbon dating timelines, state crime lab capacity constraints, and repatriation costs represents a natural content extension with continued monetization potential as the story develops.
