A woman arrested Wednesday on murder and attempted murder charges in connection with a Mobile County homicide — the third suspect charged in connection with the Aug. 7 incident — provided the gun that left a man dead and a woman injured in Grand Bay, authorities said.

Mobile County sheriff’s detectives determined Brittany Mentor “was a willing participant” with suspects Jesse Darrell Brown, and Thomas Nickols Marshall in the slaying of Horace “Bubba” Eugene Sellers, the office said.

Mentor was in the same vehicle as Brown and Marshall when the shooting occurred, the sheriff’s office said.

She allegedly confessed to providing and then hiding the gun used in the shooting that killed Sellers and injured a woman, whose name was not publicly released.

Mentor was arrested Wednesday on charges of murder and attempted murder.

The victims, who were shot in the 10000 block of Hall Road in Grand Bay while gathering the female’s belonging, were able to flee to a Chevron gas station at 13320 Highway 90 to get help, the office said.

Sheriff’s deputies at the Chevron found the female with a gunshot wound to her upper back and Sellers with a gunshot wound to his upper back.

Sellers died while being treated at a local hospital, the sheriff’s office said. The female was recovering in the hospital, authorities said at the time.

Detectives with the sheriff’s office interviewed the female, who said she went to gather her belongings when Brown and Marshall allegedly came to the location and started shooting at her and Sellers.
