HOUSTON — Houston authorities say a gunman who wounded six people at a strip mall on the city’s southwest side before dawn Monday is dead.

The Houston Police Department said via Twitter the suspect was “DOA” at the contained scene. An hour earlier, they tweeted authorities had shot the suspect.

Fire Department Assistant Chief Richard Mann said six people were wounded. A couple of them were taken to a hospital, while the others have less serious injuries.

Circumstances of the shooting, which happened about 6:30 a.m. Monday, were not immediately clear, although some witnesses have described the gunman firing dozens of shots at cars passing through the neighborhood before he was engaged by police.
