Police in southern Wisconsin are seeking a man with multiple felony convictions in connection with the death of a town of Delton man whose body was discovered in his vehicle Monday afternoon behind a Baraboo casino.

The victim, a man in his 80s whose name has not yet been released, was found at about 1 p.m. Monday, roughly two hours after a family member reported him missing.

Sauk County Sheriff Chip Meister says investigators are searching for 68-year-old Robert Pulvermacher, of rural Middleton, in connection with the man’s death. Police say the death is being treated as a homicide; autopsy results are pending. A younger man who was seen leaving with Pulvermacher has been contacted and was ruled out as a suspect, police said.<

“He (Pulvermacher) is said to frequent casinos in Madison and Baraboo, regularly playing table games such as blackjack,” Meister said.

Pulvermacher, who is currently under community supervision with the Department of Corrections, has a lengthy criminal history that includes convictions for various crimes in Adams and Juneau Counties and an escape from a federal minimum security prison in Duluth, Minn., according to a Wisconsin State Journal report.

Court filings show Pulvermacher was in 1999 sentenced to 11 years in prison in Adams County on charges of first-degree reckless endangerment and firearm possession by a felon following his arrest there after Pulvermacher pointed a gun at a deputy during a struggle.

Police say Pulvermacher had stolen the gun from a town constable in Juneau County three days earlier. He received a 3½-year prison sentence for illegal gun possession in that incident. His Adams County sentence also included 11 years of probation for false imprisonment, WSJ reports.

In 1998, Pulvermacher was questioned as a possible suspect in the death of the Rev. Alfred Kunz, whose body was found in a school adjacent to St. Michael’s Catholic Church in Dane. That case remains unsolved.

Meister asked anyone with information about Pulvermacher to call 911.
