A Snyderville Basin man was arrested in late January after what prosecutors describe as a violent sexual assault against his wife in a house in Park City.

Donald Reigelsperger, who is 58 years old, faces six charges stemming from the Jan. 26 confrontation -- four counts of aggravated sexual assault, a count of aggravated kidnapping and a count of aggravated burglary. Each of the charges is a first-degree felony, punishable by a prison sentence of five years to life and a $10,000 fine upon conviction.

Reigelsperger is being held at the Summit County Jail. Bail is set at $250,000, cash only. He is scheduled to appear before Judge Todd Shaughnessy on Monday. He has been appointed a public defender, David Shapiro. The public defender by late in the week had not been presented the charging document and declined to comment about the case.

Prosecutors on Jan. 31 filed the seven-page charging document in Third District Court at Silver Summit, claiming the confrontation between Reigelsperger and his wife occurred three months or so after the wife left him and said she wanted a divorce. They have been married 28 years and owned a property-management company, the prosecutors said.

The Jan. 26 confrontation occurred on Morning Star Court in a house managed by the company owned by Reigelsperger and the victim, Matthew Bates, the lead prosecutor, said. The charging document claims Reigelsperger held her at the house at gunpoint. The prosecutors said police officers later found that the weapon was a BB gun that looked like a semiautomatic handgun. Morning Star Court is a small street in Thaynes Canyon.

Reigelsperger allowed her to leave and told her she "better hurry or he might change his mind," prosecutors said in the charging document. She drove away and called 911, according to the prosecutors.

Police officers found him at the house and he walked out the front door with the BB gun, the prosecutors said, describing that he was told to drop the gun. He did so and was taken into custody.

The Park City Police Department arrested him on Jan. 31, Bates said.

"This is a case we will take very seriously," Bates said.
