Authorities say a 15-year-old Florida boy was charged in his mother’s strangulation death after her body was found buried at a nearby church.

Volusia County Sheriff Mike Chitwood told news outlets the teenager was arrested early Saturday after the body of 46-year-old Gail Cleavenger was found under a church fire pit. Investigators say the boy killed her after they argued about his school grades.

Chitwood says he faces murder charges. It was unclear Saturday if he has a lawyer to represent him. The Associated Press typically does not identify juveniles charged with crimes.

After the killing, authorities say the boy called friends to help him make it look like someone had burglarized the home. The boy initially told deputies his mother was missing.

The two 17-year-old friends face multiple charges.
