A weekend argument between best friends left one dead and the other in jail.

Coy Lynn Bartlett, 20, and Aaron Thrift, 21 grew up together and graduated from Mortimer Jordan High School together in 2014. On Saturday night, authorities said, a dispute between the two turned deadly.

The friends were at Thrift's home in the 400 block of Park Avenue in Kimberly. That's when, according to authorities and friend, Thrift grabbed a rifle and shot Bartlett in the head. Bartlett was taken to UAB Hospital, where he was pronounced dead at 12:38 a.m. Sunday, according to the Jefferson County Coroner's Office.

Thrift was booked into the Jefferson County Jail just before 6 a.m. Sunday and remains behind bars without bond. Both Kimberly police and the Jefferson County Sheriff's Office responded to the scene. The sheriff's office referred all questions to Kimberly police, and multiple efforts to reach Kimberly police officials over the past 24 hours have been unsuccessful.

Friends and family are mourning their loss. "We all grew up together,'' said friend Josh Jinright. "It's pretty hard."

"Coy was such a good guy. Everybody was his friend,'' Jinright said. "He had the sweetest heart, and was always right there when you needed him."
