BOSTON (CBS) — It’s a trip he’s taken a thousand times, but this time it changed with a thud.

Monday morning Karl Heitelberg was on the Mass Pike going under the Prudential Tunnel when something fell onto his car.

“Oh we heard it, and we jumped,” said Heitelberg. He pulled over and his passenger called 911.

While they escaped injury they didn’t escape insult because he says a sergeant with the state police told him it was probably road debris kicked up by another car and that there would be no investigation.

Heitelberg said there was no way it was road debris. “We didn’t have any cars or trucks in front of us or to the right of us. It came from above.”

He took pictures of his BMW with a shattered sunroof. Whatever hit his car he says did the damage then bounced off onto the Mass Pike.

“I would have thought state police would have taken a look to see what happened and to insure it wouldn’t happen to someone else, but they didn’t.”

The Massachusetts Department of Transportation said they had no reports filed yesterday regarding falling debris. When WBZ-TV contacted state police they told Jonathan Elias that if someone were to report falling debris from a tunnel they would investigate and if true contact MASSDOT, but in this case that didn’t happen. MASSDOT said no report had been filed Tuesday.

Heitelberg say it’s the lack of response, the lack of accountability by everyone in the department. “They wanted to pay the claim and move on, and that’s not the real issue, the real issue is public safety.”
