HOUSTON (AP) – Houston bomb squad technicians are inspecting a Porsche believed to belong to the man police say opened fire at passing cars in a neighborhood, wounding nine.

Interim Police Chief Martha Montalvo says the gunman had several weapons but declined to immediately describe them.

Authorities haven’t identified the gunman, except to say he was a lawyer that lived in the neighborhood who was having problems with his law firm. Bomb squad officers also were examining his residence.

Houston Mayor Sylvester Turner was in Cuba for a trade mission but told KTRK-TV that it was “very very early” in the investigation.

One witness, 30-year-old Antwon Wilson, says he inadvertently drove into the shooting scene after dropping off his girlfriend at work and could “literally hear the gunfire flying.” He managed to flee and escape injury.

One person is in critical condition and another is in serious condition.
