MEMPHIS, Tenn. — A threatening Facebook message helped police link a man to a murder in North Memphis, and the suspected killer allegedly even shared a Gofundme post to pay for the victim’s funeral.

On Dec. 29, police found Darnell Appling shot dead in a parking lot in the 1000 block of North Watkins.

Appling’s mother showed police a Facebook message threatening Appling that had been sent from a user called KashSt Mack. Police say that was the handle used by suspect Lamarcus Smith. The message said, “You better put your [explative] on a leash before something happens to you.”

Smith was referring to his ex-girlfriend and the mother of his child.

Smith turned himself in on aggravated assault warrants on Jan. 9, and confirmed the Facebook account belonged to him. He also said he was with his girlfriend the night of the murder.

His girlfriend told police that Smith had stolen her gun and used it to shoot Appling.

Smith, 24, was charged with first-degree murder and given no bond at court Tuesday.

Appling’s mother said her son was with Smith’s ex-girlfriend the night he was killed and was in her car when he and the car were shot up. She said Smith was upset at Appling for having a relationship with the woman.

She also said Smith and Appling were friends and had known each other for four years. The mother had even met Smith on several occasions.

“They called each other their cousin, they were almost like his best friend, so it is hard to believe you would do that over a female,” said the victim’s mother.

After the shooting, Smith shared a GoFundMe on his Facebook page to help pay for Appling’s funeral, with the caption “ANYTHING HELP.”

Smith will be back in court on January 31.
