WAUSAU - A 41-year-old former Wausau man has been charged with hiding a corpse after he placed the body of an Adams County man who had overdosed into a hotel closet and left it there for months, according to court records.

Daniel D. Allen, whose current address is listed as Dodge Correctional Institution in Waupun, was staying at the Village Inn in the village of Marathon when Brian J. Kienast, 28, overdosed on Nov. 22, 2017, according to the criminal complaint filed Friday.

Allen tried to revive Kienast with Narcan, which is a drug used to counteract the effects of heroin, but it didn't work, according to court documents. Allen "freaked out" when he realized Kienast was dead and locked himself into a room across the hall from the room he was renting, according to documents.

The owner of the hotel found Allen in the room that should have been vacant and called police for help in removing Allen, according to court documents. Police searched the room where Allen was found, but they did not search the room Allen was renting, according to court documents.

Allen, who was arrested on Nov. 22, 2017, for disorderly conduct, came back later and moved the body from a bed in the room he was renting to the closet in the room where the owner found him, according to court records.

About five months later, on April 19, 2018, the hotel owner went into the room where Allen had put the body and noticed a bad smell, according to court documents. The owner thought the drain traps in the room, which hadn't been rented since 2017, had dried out and was causing the smell. After investigating the drains, the hotel owner opened the closet door and found a decomposing body, according to court documents.

An autopsy was done on the body and it was identified as Kienast, who had been reported missing on Nov. 22, 2017, according to court documents.

Investigators talked to a man in the Buffalo County Jail on April 24, 2018, according to court documents. The man's name also was listed on the room rental where Allen stayed. The man in jail told investigators that Allen had told him Kienast had overdosed while with Allen, but the Buffalo County inmate had been in the Marathon County Jail that day, according to records.

The inmate told investigators that Allen had wanted him to help move Kienast's body from the hotel, but the inmate wanted no part of being involved with a drug overdose death.

If convicted, Allen faces a maximum of 18.5 years in prison for hiding a corpse. Allen currently is serving a seven-year prison sentence for drug-related charges. He was sentenced Aug. 27.
