Texas gunman legally purchased AR-15 used in the attack.

Texas mall shooting witness says he found a girl with 'no face' at the scene: "It's just unfathomable to see carnage"

Mauricio Garcia, the gunman who murdered eight people and injured seven others at a mall in Texas on Saturday, purchased the guns used in the attack legally.

A law enforcement source told CNN on Monday that the AR-15 Garcia used to carry out the attack before he was killed by an officer, was purchased legally.

Garcia also had a handgun on him at the time of the shooting and more weapons and ammunition were found in his car.

The source told CNN that all of Garcia’s weapons were purchased legally over time from private sellers in Texas. That means Garcia didn’t have to go through a federal background check.

“This was not an instance where he rushed to buy weapons prior to the attack,” the source told CNN.

A motive has not been revealed for the shooting yet, but federal agents are investigating social media postings from Garcia expressing neo-Nazi and white supremacists views.
