Police: 2 SC Teens Angela Brooks, Ashley Cushman Killed Execution Style

AUGUSTA, Ga. -- Two South Carolina teenagers found dead Thanksgiving moing were shot in the backs of their heads execution-style, Georgia investigators said Monday.

Angela Brooks, 19, of Warrenville and Ashley Cushman, 17, of Beech Island, were kneeling or lying side-by-side on the ground when they were shot, Richmond County Sheriff's Capt. Scott Peebles said at a news conference.

Police are looking for Travis Lorenzo Berrian, 26, who was described as a person of interest earlier in the investigation but is now considered a suspect. Investigators also are looking for a second man who can be seen on surveillance video getting out of Cushman's 1999 Cadillac Escalade at a convenience store early Thursday moing.

The car was found abandoned before the bodies were found in a wooded area near downtown Augusta, police said.

Peebles said Cushman and Berrian had an off-and-on relationship and the teens went to visit him Wednesday night.

"They had had some significant issues leading up to Thanksgiving moing that I cannot get into," Peebles said of Cushman and Berrian. "We have speculation, right now, and we have ideas on motives. We have many theories floating at this point."
