A motorist who had been drinking and driving struck a man sitting on his porch Thursday morning, causing injuries so severe that both legs of the victim may have to be amputated, police said.

The crash occurred at 2:21 a.m. in the 1900 block of North Acadian Thruway East at Gus Young Avenue, police Sgt. Don Stone said in a news release.

A preliminary investigation showed the driver of the 1999 Lincoln Town Car, heading north on North Acadian, lost control of the car, swerved to the left and hit a utility pole, the release says.

The utility pole broke, with attached wires pulling down two other utility poles, the release says.

The car then struck a fence at 1933 N. Acadian Thruway E. before proceeding to 1943 N. Acadian Thruway E. and hitting the victim, the release says.

The car then hit another fence, spun and came to a stop, the release says.

The victim, whose identity was not released, suffered severe injuries to both legs, according to the news release.

The extent of his internal injuries are unknown, the release says.

The driver, Marcus Hayes 34, 5646 Adams Ave., was booked into parish prison on first-offense DWI, reckless operation, failure to maintain control, suspended driver’s
