One person was killed and three others injured after shots were fired Wednesday evening in the Cielo Vista Mall in El Paso, Texas.

“We have one person in custody. We do believe there could be one outstanding. That’s why the extensive search of the mall is being done right now,” Sgt. Robert Gomez said.

A motive behind the shooting is under investigation. Police did not provide details on the conditions of the three victims who were injured.

“It was chaotic. People did flee. They were scared,” said Gomez.

After receiving reports of shots fired, police asked the public to avoid Cielo Vista Mall, which is adjacent to a Walmart where a mass shooting in 2019 killed 23 and left nearly two dozen more injured.

“Mall scene is still active please avoid the area. Multiple agencies responding to the area,” EPPD said in a tweet Wednesday afternoon.

Several videos show security gates down and police parked outside.

Gonzalez recalled the 2019 mass shooting, saying today’s experience “just brought back bad memories.”
