The man, whose name was not released, is being treated at Hackley Hospital in Muskegon. He suffered severe and life-threatening trauma to his head.
Police responded at 9:42 p.m., just as the Coast Guard Festival fireworks were about to get underway.
The investigation has revealed that the victim was a passenger in a van that entered the McDonald’s parking lot, according to Grand Haven Public Safety Director Jeff Hawke.
The victim exited the van from the passenger side and walked through the parking lot at the rear of the building near the drive-thru service lane. He was then struck by the van in which he was a passenger, Hawke said.
The van sped from the parking lot after striking the victim.
The driver of the van has been identified and the police investigation continues. Once the investigation is concluded, the case will be reviewed by the Ottawa County Prosecuting Attorney’s Office for possible criminal charges, police said.
