Police in Tennessee are searching for a 23-year-old white man who stands 5’5″ and weighs approximately 108 pounds after he allegedly admitted in a Facebook post that he killed his mother and his friend.

Casey Lawhorn called the East Ridge Police Department and told officers he shot his mother, Vi Lawhorn, and his friend, Avery Gaines, early Sunday morning before he drove off, the Chattanooga Times Free Press reported.

In the now-removed Facebook post, Lawhorn allegedly wrote that he shot and killed both adults “with a stolen .22 [long rifle].”

Mississippi’s Jasper County Sheriff’s Department said on Sunday evening that Lawhorn’s car was found abandoned on Interstate 59, but that Lawhorn was not in the vehicle.

 

In the Facebook post uploaded around 5 p.m. Sunday, Lawhorn described in graphic detail that within “probably 3 or 4 minutes,” he killed his mother, who “was completely wasted” after picking her up from a bar, as well as Gaines, a man Lawhorn described as “a close friend.”

Police said Lawhorn, who wrote that he was broken down on Interstate 59 in Mississippi when he posted to Facebook.
