A man mistakenly released by the Wisconsin Department of Corrections, then turned into deputies after he reported to his probation officer, has been charged.

Issac Sprotte faces a charge of first degree reckless homicide in the drug death of James Buley on December 27, 2006.

If convicted, he faces up to 40 years in prison.

According to the criminal complaint, on that night in 2006, Buley's mother found him unresponsive and unconscious in their home in Fox Point.

Police found evidence including a hypodermic syringe, and an autopsy showed that Buley died of heroin intoxication.

A confidential source told a Milwaukee police detective that Sprotte had obtained heroin for Buley on the night he died, and the source also informed an investigator that Sprotte had talked with Buley that night, and that he had "slammed a half gram."

The complaint states that Buley and Sprotte had been together that night, playing cards with Sprotte's mother.

On June 4th of this year, corrections officers had released Sprotte after seeing in a search on May 26th that records showed no outstanding warrants had been issued against him.

A warrant had been issued on May 21st, but that warrant had not been entered into the system on May 28th, two days after the search into Sprotte had occurred.
