Federal investigators are taking a close look at the ideology of the gunman who opened fire Saturday (May 6) on a Dallas-area outlet mall to find a motive for the shooting that killed at least eight people.

The Associated Press reports that authorities found clues that suggest Mauricio Garcia, 33, had an interest in White supremacy and neo-Nazi views.

Investigators said they found a patch on Garcia’s chest when he was killed by police that read “RWDS,” which stands for Right Wing Death Squad and is popular among right-wing extremists and White supremacy groups.

According to Newsweek, social media users noted that members of the Proud Boys, a far-right organization, also wear the patch, but there’s currently no evidence linking Garcia to the group.

Proud Boys leader Enrique Tarrio pleaded guilty in 2021 to burning a stolen BLM banner from Asbury United Methodist Church, an historic Black church in Washington, D.C., during a pro-Trump rally in December 2020.

According to authorities, investigators are now reviewing Garcia’s social media posts and accounts, as well as speaking with his family members and associates about his beliefs. But a law enforcement official connected to the ongoing investigation declined to share details with the AP and said it is too soon to draw a conclusion.

Numerous shoppers were at the Allen, Tex., mall when gunfire started at about 3:30 p.m., authorities said. Witnesses said Garcia wore a tactical vest packed with multiple ammunition magazines. In addition to the eight people fatally shot, at least seven others were wounded before a police officer who happened to be near the mall shot and killed Garcia.
