According to the Isabella County Sheriff's Department, a 25-year-old Mount Pleasant female was struck down by a 1988 Cadillac DeVille, allegedly driven by Grinzinger, on East Bluegrass Road just west of Collegiate Way in Union Township at around 1:30 a.m. Sunday.

The victim was in the process of crossing Bluegrass Road when she was hit by the westbound traveling vehicle, according to the release.

According to police, Grinzinger initially fled the scene but returned within a few minutes and was arrested.

Grinzinger is charged with operating while intoxicated causing injury, failure to stop at the scene of a personal injury, failure to report an accident, zero tolerance, which requires 360 hours of community service and a minor in possession. He could face more than six years in jail, more than 360 hours of community service and $100 in fines.

According to court documents, the victim was laying on the roadway in a puddle of blood from a severe head injury when police arrived to the scene of the accident.

Witnesses stated in the documents that Grinzinger's car had struck her, and then stopped for a few seconds without ever attempting to aid her or identify himself before fleeing the scene.

Grinzinger arrived back at the scene during the investigation and stated he was sorry and that he left because he was scared and shaken up.

The documents stated that Grinzinger claimed he was westbound on Bluegrass Road when the victim crossed the street in front of him. He claims to have tried to avoid her.

Grinzinger admitted to drinking prior to the accident and the responding officer smelled a strong odor of intoxicants on his breath, according to court documents.

His PBT Breathalyzer test was a 0.06. In Michigan, 0.08 is considered under the influence.

Principal Trial Attorney Bob Holmes said Grinzinger's blood-alcohol level during the incident has yet to be determined, as the prosecutor's office is waiting for the results of a toxicology test.

Holmes said the victim is recovering with the help of her family, and was released Wednesday from Covenant Healthcare, 800 Cooper Ave, Saginaw.

The victim spent four days in the hospital and was shipped to Covenant after initially being treated at Central Michigan Community Hospital, 2120 S. Mission St.

She has more than 100 stitches in her head, a broken leg and uses a walker and neck brace, Holmes said.

According to a police press release, she suffered multiple broken bones and head trauma resulting from the accident.

Holmes said the victim could have died.

"Anytime you have someone who was ran over by a car, its pretty serious," he said. "But it could've been much worse."

Grinzinger's parents supported him during his Thursday arraignment.

Holmes said Grinzinger's family has expressed concern for the wellbeing of the victim.

Grinzinger has no previous criminal history and is not being tried as a habitual offender.

His preliminary hearing is scheduled to take place at 8:15 a.m. Aug. 27 at the Isabella County Courthouse, 300 N. Main St. He is currently out on bond.
