A 22-year-old Billings man admitted Monday to causing the death of a motorcyclist in a hit-and-run crash in June.
Tanner Jean Reichert, 22, appeared before District Judge G. Todd Baugh and pleaded guilty to negligent homicide for the June 8 death of 40-year-old Daniel Oltrogge.
Reichert also admitted to a second felony charge of failing to remain at the scene of a crash involving death or injury.
Baugh scheduled a sentencing hearing for Jan. 14. A plea agreement said prosecutors will request that Reichert serve 20 years at Montana State Prison for the homicide, and an additonal 10 years in prison for leaving the scene.
Reichert admitted that he had been drinking and was driving to the house of a friend when he struck a motorcycle from behind on Old Highway 10 East near Laurel shortly before midnight.
Reichert left the scene but turned himself in the next day. He initially said he thought he hit a deer.
Investigators said Reichert drove away from the scene, continuing until his vehicle broke down.
At the scene of the crash, investigators found several deep gouge marks in the roadway. The motorcycle driven by Oltrogge was pushed nearly 500 feet from the point of impact, court records state.
Oltrogge died at the scene.
