A man who shot and injured nine people before being shot dead by police on Monday near a shopping center in Houston, was wearing a vintage military uniform with a Nazi symbol, police said. The shooter was identified as attorney Nathan DeSai. Officials said the man had 2,600 rounds of ammunition both on him and in his car with several semi-automatic weapons.His apartment was filled with historic and vintage military items dating "back to the Civil War," Houston Police Department Captain Dwayne Ready said on Monday evening.DeSai's father confirmed that his son owned several guns and had a license to carry, according to Fox News.Public records showed that DeSai lived in a condominium near the shooting scene and that he had no criminal record.DeSai, who received his law degree from the University of Tulsa in 1998, started a small law firm but his former law partner, Ken McDaniel, said they closed it about six months ago.McDaniel told local television the shooting was "out of character" for DeSai.Houston Mayor Sylvester Turner, in Cuba to develop trade relations, told reporters, "The motivation appears to be a lawyer whose relationship with his law firm went bad."Prakash DeSai told ABC television's Houston affiliate that his son drove a black Porsche, and that he was "upset about his law practice not going well" and money woes.The police bomb squad secured the shooter's car, which contained more than 2,600 rounds of ammunition. Police said a handgun was found on the suspect's body and a rifle was found in this car.An agent for the Bureau of Alcohol, Tobacco, Firearms and Explosives said the firearms had been legally purchased.Christopher Miller, who lives near the site of the shootings, said he watched much of it from his apartment. "The only way I can explain it is like a firework show; you hear a shot, a shot, then more shots, then a finale of a bunch of shots. Then you know it's over."Police said more than 75 shell casings had been recovered.
