A Houston lawyer whose business was struggling opened fire on morning commuters on Monday, injuring at least nine people before being shot dead by police, authorities said.
Six people were taken to hospitals and three were treated at the scene after being shot at while inside their vehicles in the affluent neighbourhood of West University Place, acting Houston Police Chief Martha Montalvo told reporters.
One victim was in critical condition and another was in serious condition but both were expected to survive, officials said. The Federal Bureau of Investigation said there was no indication that the shootings were linked to a radical group.
Police declined to identify the suspect, but local media reported that he shot at vehicles from a black Porsche registered to Nathan DeSai.
Public records showed that DeSai lived in a condominium near the shooting scene and that he had no criminal record.
