Mario Scales, 31, of Memphis, pleaded guilty to second-degree murder Wednesday in connection with the slaying of his wife. She was shot more than six times with an assault rifle. 

The incident happened April 3, 2017, according to the release from the district attorney’s office. 

The victim, Lisa Peoples, 27, was found dead from gunshot wounds around 9 p.m. near her driveway. 

Investigators said Peoples had previously taken a protective order out against Scales. 

Witnesses said after the shooting, Scales told people inside the home what he had done before running away – still armed with an AK-47 rifle. 

Scales was arrested later while hiding inside a nearby house.

Scales was arrested on March 20, 2017, for assaulting the same victim of the shooting after police say they found a Glock 22 in his car with live ammunition.
