TOWN OF DUNKIRK, Wis. -

A Stoughton man was arrested Monday for allegedly supplying heroin to a 26-year-old who overdosed on Friday, according to a release.

Around 9:10 p.m. on Friday Dane County sheriff’s deputies and Stoughton EMS responded to 400 Pleasant View Drive for reports of a 25-year-old man who was found unconscious inside his home, officials said.

The 25-year-old was transported to Stoughton Hospital, but died despite life-saving efforts, according to the release.

There was clear evidence of heroin use in the home, and investigators said Robbert S. Knipfer, 26, of Stoughton, was likely responsible for supplying the heroin that caused the death.

Knipfer was arrested Monday on a probation hold, according to the release. Investigators are waiting for the medical examiner’s report and toxicology results to determine additional charges.
