Nazi materials were found inside the car of attorney Nathan DeSai, who shot six people and wounded another three in Houston, according to media reports. He was dressed in a  Nazi uniform and Nazi paraphernalia were found inside his car and apartment, according to them.

Capt DW Ready, head of the homicide division of the Houston police department, did not cofirm this. He said that the shooter was dressed in some kind of military uniform and had Nazi emblems with him and at his house. He said the emblems may have been collector's items. At the shooter's home, police found vintage military equipment and paraphernalia dating back to the Civil War. ‘He was wearing a military-style apparel, I don't know exactly what nationality or exactly what army or anything like that,’ Ready said.

‘At this point we are very open-minded as to the motive,’ said acting Chief of HPD Martha Montalvo.

But Indian activists pointed out that probably they might have been mistaken seeing the Swastik, a Hindu symbol denoting good things. There were efforts by the community earlier to get acceptance for Hindu Swastik, but still most people relate the symbol to the Nazi regime and the brutalities of that period.

DeSai was 46 and was unmarried. He served as a former prosecutor in Dallas County and also played in a band.

According to DeSai's family members, he had dinner with his parents Sunday night and that was the last time they spoke with him. On Monday morning, they saw his car on the TV and called him without getting any response.

After the law firm, where he was a partner was dissolved in February, he was working from his condo, which was near the scene of the shooting. DeSai's former law partner, Kenneth McDaniel, said that they dissolved their partnership due to economic reasons. McDaniel said he had not spoken to DeSai since February.

‘It's a horrible situation, I don't like hearing anything that's happened... Not only to Nathan, to everybody that is involved and I don't know what to say,’ McDaniel told the media.

Nine officers were involved in the gunfight while assisting wounded citizens, Ready said. The gunman took cover behind a tree, he said.

Deasi was shooting randomly at passersby as well as anybody he could put his sights on, Ready said. More than 75 expended shell casings were found at the scene, and the gunman had 2,600 rounds of ammunition for his .45-caliber pistol and .45-caliber Thompson carbine rifle, which carried a 40-round clip, Ready said.

The rifle was purchased legally in 2009, and the handgun was purchased legally in 2011. The daily reported that police found in his flat several military items that went back to the Civil War.

Desai’s father Prakash Desai told ABC News that his son was depressed because his law practice was not going well. He said he was not getting any business and he was upset for a long time.

Prakash Desai said his son lived near Weslayan and Bissonnet, the site of Monday's shooting.

Forty six-year-old Nathan Desai owned several guns to protect himself against his clients, some of whom were "funny people and criminally-minded people", his father said.

Houston Chronicle said that Prakash Desai is a retired geologist

Police said one of the victims was critically wounded and another was seriously wounded. Most of the others were discharged from hospitals.

DeSai earned his bachelor's degree in psychology from the University of Houston in 1993 and his law degree from the University of Tulsa in 1998. He practiced business, family and criminal law.
