City officials identified the attorney who injured nine people Monday in a shooting in southwest Houston as Nathan DeSai, the Houston Chronicle reported.

DeSai opened fire, apparently at random, at people as they were in their vehicles on Monday, according to police.

Firefighters stumbled upon the shooting-in-progress when they arrived at the intersection of Bissonnett and Weslayan streets around 6:30 a.m. in response to a call about a discharged firearm, Assistant Fire Chief Richard Mann said.

DeSai "was firing actively at officers" when police arrived, Montalvo said. DeSai was shot and killed by police.
