A gunman who wounded nine people near a shopping center in Houston this morning was dressed in a "military-style" uniform and had Nazi emblems, police said.

Police first received a call of firearm discharge at 6:29 a.m. local time. When they arrived at the scene, the suspect, a lawyer, was inside his car armed with two guns and firing randomly at people passing by. Police shot and killed the gunman and he was pronounced dead on scene, according to the Houston Police Department.

More than 75 shell casings were recovered from the scene from shots fired by both the gunman and officers, Houston Police Department Captain Dwayne Ready said at a news conference tonight.

Six people were transported to the hospital for injuries, including one in critical condition and one in serious condition who are expected to survive. Three others were treated and released, police said.

Investigators searched the suspect's vehicle and nearby apartment. Nearly 100 pieces of evidence have been collected thus far, police said.

Officials recovered a .45 semi-automatic handgun, .45 semi-automatic "Tommy Gun," 2,600 rounds of live ammunition as well as vintage Nazi emblems and civil war paraphernalia from inside the suspect's Porsche and person. Nazi emblems and military items "going back to the Civil War" were also found inside the man's apartment, Ready said.

Officials would not confirm the name of the suspect, who police say is believed to have acted alone.

The Bureau of Alcohol, Tobacco, Firearms and Explosives and the FBI are assisting the ongoing investigation.

Houston Mayor Sylvester Turner, who is in Cuba for a trade mission, told ABC-owned station KTRK-TV that the incident may have been related to the suspect's work.

"[The suspect] was either fired or had a bad relationship with this law firm," Turner said.
