Police in El Paso are trying to identify a man who they say saved several lives during the mass shooting earlier this month at a Walmart.
El Paso police on Thursday shared a surveillance camera photo of the man, saying that he's considered a "hero" and that authorities need to interview him.
Police said on Twitter that the man's actions were "critical and lifesaving" and that he's believed to have saved many lives during the shooting, including an infant's.
El Paso Police Sgt. Enrique Carrillo says police are not releasing details of what the man did because that information is needed to verify his identity.
Police say a gunman has confessed to targeting Mexicans in the Aug. 3 attack in which 22 people were killed.
