NEW ORLEANS (AP) — An off-duty police officer was killed when he drove off an open drawbridge in early-morning darkness Tuesday, and his superintendent said no warning bars or arms had warned the man he was about to plunge to his doom.

A spokesman for the Louisiana Department of Transportation and Development, which operates the lift bridge over the Industrial Canal, said the agency is investigating. Lift bridges raise their middles in one piece rather on two hinges.

The body of Tommie Felix, a police officer for 17 years, was inside the silver BMW that was pulled from the canal Tuesday afternoon, New Orleans police Superintendent Warren Riley said.
