A mother and son argued about the boy getting a near-failing grade in school; shortly after the disagreement, the mother is dead. Authorities believe the 15-year-old son killed his own mother.

A Florida sheriff said early Saturday that the boy, Gregory Logan Ramos initially claimed that he came from school to discover their house ransacked with his mom nowhere to be found inside, while her van was still running in the driveway.

The cops were not convinced with the boy’s statement, and when further questioned, Ramos confessed his horrific crime. The teen admitted that he strangled his mother, 46-year-old Gail Cleavenger, late Thursday night. Ramos said he used a wheelbarrow to load his mother into her van and bury her beneath a fire pit at River City Church in DeBary, just northeast of Orlando.

Ramos got a “D” in school and got into an argument with his upset mother over the failing grade. The teen was further upset his mother called his father, who was out of town on a business trip.

Ramos is charged with murder after the police got what they describe as the teen’s “full and detailed confession.”

The son also confessed that he got two of his friends to help him pull off the supposed burglary. Those teens, both 17, are Dylan Ceglarek and Brian Porras. Police say they they are also facing multiple criminal charges.

Deputies found property that was taken from the house for the “staged burglary” including computers and other electronics including a Playstation 4, a rifle and other items. They also recovered a shovel and broom that were used in disposing Cleavenger’s body.

Sheriff Mike Chitwood was shocked by the murder: “the case we worked tonight was one of the most disturbing and saddest I’ve seen in my career.”

Chitwood added, “Gail has all of us fighting for justice for her. God bless Gail Cleavenger and all who knew and loved her.”
