A bumped up reward is netting a surge of tip calls in the investigation into the I-96 corridor highway shootings. Tip calls have grown exponentially since the reward increased to $102,000 Monday, jumping from around 600 to more than 1,000.
"This did exactly what we thought it would, it would prod some people's memory and pry their lips open," Ingham County Sheriff Gene Wriggelsworth said.
Wriggelsworth hopes one of those callers will be close with the suspect, perhaps a friend who could be a game-changer for the investigation.
"People get greedy in all walks of life," Wriggelsworth added.
In the meantime, task force members are actively patroling the entire I-96 corridor. They've identified hot spots, investigators will focus on and say they do have solid leads. They will not reveal those to protect the investigation.
News 10 rode along with one of the deputies assigned to the case Tuesday. She patroled near the Ingham, Livingston county border looking for vehicles matching the suspect's description and anything out of the ordinary.
Police say the gunman may be driving or he could be aiming from behind a tree. With 25 shootings and now an injury, investigators are considering every possibility.
"We've always regarded this as a very dire situation, when you start shooting at cars, it's a miracle that nobody got hurt before," Wriggelsworth said.
Law enforcement wants drivers to be vigilent and aware of their surroundings, but says the freeways are still safe, especially with the boosted patrols. Between local, state and federal resources, more than officers are working the case each day.
Much of that work is patient observation, at other times it's active. The task force stopped several dark-colored sedans Tuesday for traffic violations.
"Somebody didn't signal for a turn or they rolled through a stop sign and boom, you got the person," Wriggelsworth explained. "I predict it's goign to be something like that."
From the streets, to the air, to the ground, he says officers are searching and ready to make an arrest.
