NBC, CNN, and ABC have identified the shooter as Patrick Crusius, 21, of Allen, Texas, which is more than 600 miles from El Paso. Police have not discussed a motive.
Gomez told ABC that the suspect was “taken into custody without incident” and said police have ruled out multiple shooters.
At 3:52 MDT, police announced on Twitter that “there are no threats to other locations or venues in the city.”
The El Paso Police Department did not immediately respond to PEOPLE’s request for comment.
Police announced that blood is needed urgently and that victims have been transported to multiple hospitals.
Multiple nearby businesses were placed on lockdown.
Blink 182’s Mark Hoppus wrote on Twitter from his El Paso hotel room: “We are locked down in our hotel in el paso. Over the intercom system they just announced that there are reports of another active shooter directly across the street at a location different from the first shootings. We were leaving breakfast when our security texted that there was an active shooter at the mall we were headed to. Saw dozens of police cars on the freeway and surface streets. helicopters. We got back to the hotel and turned on the news to see what was happening.”
Oscar Collazo, the manager of Landry’s Seafood House, one of the businesses on lockdown, told CNN that three Walmart employees who seemed “shook up” had come in to seek safety.
“We never thought it would be so close to us this time,” Collazo told the outlet. “You see on the news all the time, but you don’t think it could happen here until it does.”
The chief of staff to the city’s mayor, Olivia Zepeda, said the suspects are in custody. It was not immediately clear how many people were in custody or how many had been killed or hurt.
Saturday’s shooting took place four days after a “disgruntled employee” fatally shot two colleagues at a Mississippi Walmart before being wounded by a responding officer and taken into custody.
