Hoppus said that his security team "texted that there was an active shooter at the mall we were headed to." The singer said he "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."

At that point, the hotel intercom system "said there are reports of another shooting across the street at the bassett place mall. i don’t see or hear police or helicopters so hopefully it’s just an over abundance of caution and someone got the malls confused. so terrible."

One suspect was taken into custody following the massacre on Saturday. The El Paso Police Department said on Saturday there were no other threats "to other locations or venues in the city."
