Many questions remain after a violent shooting at the Randalls supermarket center on Weslayan at Bissonnet.
A bomb squad cleared a vehicle near the scene. The Porsche in question is registered to Nathan DeSai.
Police would not identify DeSai as the shooter, but said they found two guns and items with Nazi emblems in his vehicle, ABC News learned. They also found Nazi materials in his apartment.
Nearly 100 pieces of evidence were collected as of Monday afternoon, including 2,600 rounds of live ammo, a .45 semi-automatic handgun and a .45 Tommy Gun.
Authorities got into a dramatic shootout with the gunman to end the rampage. Authorities confirmed the suspect died from his injuries.
The Houston Fire Department said people were taken to area hospitals after they were injured by the shooter. Three were treated at the scene and released.
One victim was in critical condition with a gunshot wound, according to Memorial Hermann Hospital. Another was in fair condition and three were in good condition.

"I literally heard the gunshots past my face," Wilson says. "It's a hard pill to swallow."
Wilson said there was a steady shooting back and forth as officers worked to bring the active shooting situation to a close.

Fire officials reported on radio that the suspect was seen behind some trees as he opened fire on vehicles in the area.
A KTRK crew saw firefighters and officers running up and down the street as the gunfire continued.
From the air, reporter Don Armstrong reported seeing bodies on the ground as officers ran between cars and buildings in search for the suspect.
