The 33-year-old shooter, a neo-Nazi sympathizer with an AR-15 style-assault weapon, was killed by a police officer who happened to be at the Allen shopping center, authorities said

Texas mall shooting suspect Mauricio Garcia interacted with neo-Nazi and white supremacist content online, two senior law enforcement officials said.

One of the officials said Garcia, 33, posted such content himself. The other official said that the suspect consumed such rhetoric online and had several social media accounts and that authorities found him with a patch with a right-wing acronym on his chest. 

Texas has been rocked by seven mass shootings since a gunman killed 21 people at an elementary school in the city of Uvalde in May 2022, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.
