Three cars were hit with windows shattered at about the same time early Tuesday morning, but police can't say if the vehicles were hit by bullets or something else.
Investigators are looking into if someone is taking aim at drivers.
Don Marceau has lived in this area for 40 years and never has he heard of someone taking aim at drivers.
"It scares the hell out of you," said Marceau. "Because we travel that everyday."
At 3:05 a.m. and again at 3:25, two northbound drivers in the area between Baldwin and Clintonville roads reported something hit their passenger side windows and shattered them.
"So far we haven't found any projectiles, any type of shell casings or anything to that effect," said Lt. Michael Shaw, Michigan State Police.
Tuesday afternoon a third driver contacted police with a similar story from overnight - same place, same time, near the Mt. Zion church.
"There is a projectile hole in the side of the car," Shaw said. "We're in the process of sending our evidence tech there to look at it. That doesn't mean it's a bullet or anything like that. But it is three vehicles in one area."
Lee Malone runs a trucking company and had drivers in the area overnight.
"Scary as heck - that's shocking," he said. "I had two of them through there at that time and that's scary to have the guys in that kind of danger.
"We're going to avoid this section of the road until they figure out what's going on - that's what we're going to do."
But Shaw says it's not necessary to change your travel plans, police suspect it could be kids.
"Usually they turn out to be either bb guns or sling shots or juveniles," Shaw said. "If you're a mom and dad and you happen to know that your kids were out late in that area last night you may want to give us a call so we can get this all taken care of."
