Deeper look into alleged Fond Du Lac stalking case with suspect out free

FOND DU LAC, Wis. (CBS 58) -- We're digging deeper into the stalking allegations against a rural Fond Du Lac County man.

Benjamin Larson is currently out on bond despite detectives finding human skulls and bones in his basement. Larson is being monitored via a GPS tracker, but there are concerns he was allowed to go free at all.

It's unclear where Larson currently is. He wasn't home when we went to his house this week. But one place he should not be in is Dane County.

Last week a judge ordered Larson to wear a GPS tracking device and banned him from returning to his victim's home county.

He also ordered a psychological assessment.

The judge initially agreed the state's recommendation of a $20,000 bond was reasonable.

But then court commissioner Alberto Quiroga said, "But I also think that the law requires me to make it somewhat plausible that he be able to not sit until trial."

Quiroga set the bond amount at $15,000. Larson posted it a few days later and was released.

Questions now center on the victim's safety:

A spokesperson for the Madison Police Department told us, "typically for cases like this the department will have safety precautions in place for the family."

The concerns stem from the disturbing allegations.

In Larson's basement, detectives found "a mummy," "a set of skeletal remains in a glass casket," "a human skull in a glass display case," and "additional skulls on shelves."

In a "padlocked room" "were 5 human skulls and 1 partial skull," plus "a human jawbone."

But assistant district attorney David Olson said, "Most concerning were some documents that were also recovered in that room. They appear to be journal entries."

There were 25 pages about the victim, her partner, and their child.

The complaint says Larson allegedly wrote, "I really ache to take their skulls, all of them. It’s a rage I can’t put into words."

And: "I just want her gone so I don’t have to know she’s still out there doing all of this with someone else.”

Larson described an alleged trip to the victim's home in Madison, "Dressed in all black, with black gloves, and a black mask."

He wrote that outside her house, "Just for fun I slowly grabbed the machete I keep in my car."

Larson called it "Hunting," in the journal entries.

"Creepy, strange, stalker-ish, potentially dangerous?" he wrote. "Yes. It is. Does this bother me? Not in the slightest."

All of these allegations stem from brief interactions in 2013: the victim saw Larson a “handful of times” over just two months.

Madison police expect to have more information for us Monday.
