Anywhere from 1,000 to 3,000 shoppers and about 100 employees were at the Walmart store when the gunman opened fire, according to police. Multiple agencies responded to the scene, including the FBI, the sheriff’s department, the state Department of Public Safety and Border Patrol. “The ages and genders of all these people injured and killed are numerous in the age groups,” Gov. Greg Abbott said at a news conference. Patrick Crusius, a 21-year-old white man from Allen, a suburb of Dallas about a 650-mile drive away, is in police custody. Authorities are looking at potentially bringing capital murder charges against him.
A source said later Saturday that the FBI has opened a domestic terrorism investigation into the massacre. Mayor Dee Margo said Saturday evening that his city would rise above this “senseless and evil act of violence.” “Today’s shooting in El Paso, Texas was not only tragic, it was an act of cowardice,” the President wrote on Twitter. “I know that I stand with everyone in this country to condemn today’s hateful act. There are no reasons or excuses that will ever justify killing innocent people.” Investigators believe the shooting suspect uploaded a 2,300 word, four page document filled with white nationalist language and racist hatred toward immigrants and Latinos on online message board 8chan, attached to a post that said, “I’m probably going to die today.”
