Jerod Green pleaded guilty to three charges stemming from the night he killed Sgt. Todd May of the Monongalia County Sheriff's Department in February 2012.
May died when Green's pickup truck slammed into his cruiser at more than 90 miles an hour along I-79 in Greene County, Pennsylvania, just over the state line.
May was along the highway that night because Green sped away from a traffic stop in Monongalia County, dragging one of the deputies a short distance, then led several deputies and other officers on a high-speed chase through back roads into Pennsylvania.
Monday, Green pleaded guilty to third offense DUI, fleeing from an officer and causing bodily injury and fleeing an officer with reckless indifference.
Those charges carry possible penalties of one to three years, three to ten years, and one to five years in prison, respectively.
Judge Russell Clawges will sentence Green at a later date.
Clawges was expected to hear motions from Green's attorney Monday to change the venue of his trial and asking the court to recuse itself. The motions stated it was unlikely Green would receive a fair trial in Monongalia County due to the high publicity of the case and the court's close ties with the Sheriff's Department.
Green is already serving a 25 to 50 year sentence in Pennsylvania for the murder of Sgt. May.
