Mauricio Garcia, the 33-year-old man who police say killed eight people Saturday at a discount mall in Allen Township, had expressed “neo-Nazi ideology,” Texas Public Safety Commissioner Hank Sibley said today, confirming reports about the content of his social media posts.

But he emphasized that it seems that he did not distinguish his victims by racial criteria, nor did he take into account their age or gender.

Armed with an AR-15 assault rifle, the 33-year-old opened fire on the crowded Allen Premium Outlets mall, spreading death before being shot dead by police.

Among the eight victims are three children – two sisters (ages 11 and 8) and a three-year-old boy, whose parents were also killed.

Ten other people, aged 5 to 61, have been injured and three are in critical condition.

In addition to the AR-15, police found seven other firearms in the killer’s possession and in his car. All had been purchased legally, Sibley noted at a news conference.

“The big question is: what was his motive? Why did he do it? We don’t know,” he told a press conference.

From the investigation of Garcia’s social media accounts, his tattoos and the “RWDS” (Right Wing Death Squad) badge he was wearing at the time of the attack, it appears that the 33-year-old had a neo-Nazi ideology.

Sibley also said that Mauricio Garcia had served in the US military and had recently worked for a security firm.
