The two victims are the suspect's mother, Vi Lawhorn, and a friend.
The Jasper County Sheriff's Office said that suspect Casey James Lawson was found dead in Vossburg, Mississippi from an apparent self-inflicted gunshot wound, according to ABC News.
In a now-deleted Facebook post, Lawhorn allegedly wrote, "This morning, at around 01:30, I shot and killed my mother (Vi Lawhorn) and a close friend of mine... with a stolen .22 LR."
East Ridge Police confirmed to WTVC that Mississippi Highway Patrol located Casey Lawhorn's vehicle in Jasper County, Mississippi, around 7 p.m. Sunday. Casey Lawhorn was not in the vehicle, police said.
This comes after Casey's brother told WTVC that he had learned Casey was traveling southbound on I-59 through Mississippi.
The name of the friend has not yet been released as the next of kin has not been notified.
