Drew Rinner, 31, was changing a tire in his driveway on Sunday afternoon when the car he was working on him fell on top of him, killing him instantly, NBC affiliateWLWTfirst reported.

“The spare was underneath the car. When he crawled under to get the spare, the jack failed and the car crushed him,” his wife Marissa, 27, tells PEOPLE, adding that the entire experience has been “very traumatic.”

Despite being heartbroken, Marissa feels a responsibility to speak out.

“I would like to bring awareness to how dangerous climbing under a car is because I don’t want anyone else to experience this,” she says. “We never thought anything like this would happen for a seemingly simple task for him.”
