The El Paso shooting suspect who killed 22 people at a Walmart in El Paso, Texas, has reportedly confessed that he targeted “Mexicans”, US media say.
An arrest affidavit obtained by some agencies discloses some confessions and his interviews while in police custody.
Patrick Crusius, the alleged shooter is the author of an online post decrying Hispanic migrants officials believe.
Authorities are said to be considering hate crime charges against Crusius, and could face the death penalty if found guilty of the mass murder.
The Washington Post and Associated Press, which received the arrest report filed by El Paso Detective Adrian Garcia, reported that he document was written last Sunday, one day after the attack on the Walmart shoppers.
The suspect is said to be seen getting out of his car with his hands up and saying “I’m the shooter” when he was stopped by an officer near the crime scene,and was said to have waived his right to a lawyer.
Mr Crusius told detectives that he had travelled from the suburbs of Dallas with an assault rifle and multiple magazines containing ammunition.
“The defendant stated once inside the store he opened fire using his AK-47 shooting multiple innocent victims,” Det Garcia wrote.
The suspect surrendered without incident, and has been co-operating with police since the attack, investigators say.
