The mother of the mass shooter at the El Paso Walmart on Saturday told attorneys she called the police recently to voice her concern about the big AK-style gun her son owned.

Patrick Crusius, who was anti-social and autistic, murdered 20 people at the Walmart on Saturday.

An attorney for the family of the man charged in the El Paso Walmart shooting rampage says the man’s mother contacted police weeks before the rampage out of concern that her son had a rifle.

Attorney Chris Ayres told CNN that the call was made to police in Allen, a Dallas suburb, by the mother of Patrick Crusius, 21.

He and fellow attorney R. Jack Ayres also said the mother didn’t identify herself or her son in the call.

They told CNN that his mother contacted police as she was concerned about her son owning a weapon given his age and lack of experience with a firearm.

During the call, she was transferred to a public safety officer who told her that her son, 21, was legally allowed to purchase the weapon, according to CNN.

Police did not seek any additional information from her before the call concluded, the attorneys claimed.

Sgt. Jon Felty, Allen police spokesman, said there was no record of such a call and he wasn’t aware of such a call.
