The court case for a former high-ranking, off-duty police officer who allegedly crashed into a teen a year ago on a New Baltimore road began Thursday in 42-2 District Court, New Baltimore police said.

William Snider, 49, is accused of hitting a Marine City teen's vehicle head-on last December on County Line Road, causing then 18-year-old driver Ryan Hagel serious injuries. Snider, whose blood-alcohol level was well over the state's legal limit for driving of .08, was charged with a felony of operating a motor vehicle while intoxicated causing serious injury, police said.

The Harper Woods lieutenant said he had already accepted a retirement package from the force before the accident and his retirement took effect soon after the December 2011 crash, according to Channel 7.

New Baltimore Detective Sgt. John Willer said Hagel, 19, took the stand Thursday and a doctor is next expected to testify Feb. 1 in district court. The case will be bound over to Macomb County Circuit Court if it's deemed there's sufficient evidence for trial.

Snider has been ordered by the court not to contact the Hagel family after reports he allegedly paid visits to their home following the accident. The defendant denied doing so.

"He never admitted to being out there," Willer told Patch.

The accident turned the teen athlete and outstanding student's life upside down, his father told Channel 7.

"He’s trying to get his life back. He was halfway through his senior year of high school. He couldn’t go to prom, couldn’t go on the senior trip," David Hagel told the station.
