SHARONVILLE, Ohio (AP) — Officials say a driver died in a car fire in front of his mother and other witnesses who couldn't help him escape the burning vehicle outside his Cincinnati-area apartment complex.

The man's car apparently burst into flames Wednesday afternoon as he pulled into a parking spot in Sharonville, roughly 15 miles northeast of downtown Cincinnati. Witnesses say the 48-year-old man tried to kick open a door and pleaded for help, but others couldn't get close enough because of the flames.

Police were withholding his name while other relatives were notified.

It wasn't immediately clear what caused the blaze. Investigators say they'll review evidence from the scene to help determine a cause.

Sharonville police Sgt. Walter Cordes says that could be complicated because the flames might have destroyed evidence.
