A manhunt is underway for a double murder suspect who confessed to killing his mother and one of his friends in a chilling Facebook post.

Casey James Lawhorn, 23, said he shot his mother Vi Lawhorn and friend Avery Gaines with a stolen .22 LR in the early hours of Sunday (April 8) at his family home in East Ridge, Tennessee, in an update on the social media site more than 1,000 words long seen by Newsweek.

In the post, which has since been taken down, Lawhorn said he killed his mother after he picked her up from a local bar.

“My mom was completely wasted, and just like every other time she gets drunk, she goes on and on, without prompt, about how devastated she’d be if I killed myself,” Lawhorn wrote.

He then described how after he “nervously paced for a few minutes” while he played out the coming events, he walked up to Gaines as he slept on the floor and shot him in the head.

Lawhorn then walked into his mother’s room where he attempted to shoot her, but the gun jammed. He left the room to fix the jam, then returned and fired twice before the gun jammed again.

"She started screaming the worst scream I've ever heard. Movies really don't do justice to how true terror sounds,” he said. "She shouted, 'You shot me! You've killed me! Why?' Once I got the jam fixed, I turned on the light so I wouldn't miss again. I shot at her twice more and it was over."

Lawhorn said he then took some cash and heroin which Gaines had on him. Police said the 23-year-old also dialed 911 to confess to the killings, but had fled the scene by the time officers arrived.

"I've spent a lot of time thinking about murder, wondering what it feels like. But I've barely felt anything,” he added in the Facebook post.

During the Facebook post, Lawhorn also described how he has felt suicidal since school and is intending to take his own life to save "state money" on executing or imprisoning him.

Police have warned the public not to approach Lawhorn as he is considered armed and very dangerous. The Jasper County Sherriff’s Department in Mississippi confirmed that they found the vehicle that Lawhorn was believed to be travelling in on I59 near the Vossburg exit, but the suspect was not inside.

Police in Dade County, Georgia, also confirmed that Lawhorn’s gold 2002 Ford Taurus with Tennessee plate number W0327L, was spotted at a gas station around 5:30 a.m. on Sunday, although there is no evidence to suggest he is still in the area. He is believed to be travelling south.



A statement from the East Ridge Police Department said: “ERPD is aware of the post made by Casey Lawhorn. We are attempting to follow up with other law enforcement agencies and working to locate Mr. Lawhorn to bring a resolution to the matter. ”

According to his Facebook profile, Lawhorn was previously employed as an operations administrator at Amazon until October. He had previously studied at Middle Tennessee State University.

In October, he posted a YouTube video on Facebook about gun control, adding how “mental health is a very important part of this conversation.” He also recently re-shared an old post from October 2015 detailing the number of mass shootings which occur in the U.S. with the sarcastic comment: “We don’t need gun control. That’s silly.”

He is described by police as a white male, 5 feet 5 inches tall, weighing around 108 pounds.
