A 15-year-old Florida boy is being charged as an adult in the death of his mother, according to ClickOrlando.

Gail Cleavenger, 46, was reported missing and endangered on November 2. Only one day later, her body was found under a fire pit at a church early that morning after officials with the Volusia County Sheriff's Office said her 15-year-old son, Logan Ramos, confessed to killing her.

Ramos admitted to detectives that he strangled his mother on Thursday night at the family's home in DeBary. Sheriff Mike Chitwood said the teenager was motivated by rage following an argument over Ramos' school grades.

The teenager told police he spent around 30 minutes killing his mom after she survived a first strangulation attempt. Ramos told investigators he used a wheelbarrow to load her body into a van, then buried her at River City Church early on Friday.

Chitwood said the case was "one of the most disturbing and saddest I've seen in my career."

Investigators said he got help from two friends to bury the body and staged a burglary scene at their house. The friends, Dylan Ceglarek and Brian Porras, both 17, are charged with acting as accessories to first-degree murder.

Ramos told police he returned home from school on Friday, then reported the false burglary and the disappearance of his mother; however, he later confessed. Chitwood said his confession was "cold and calculated" and lacked emotion.

"He is a soulless individual who thought he was gonna outsmart everyone in the room," Chitwood said. According to ClickOrlando, the sheriff called Ramos one of the "top three sociopaths" he has ever encountered.

On November 15, officials announced Ramos was being charged as an adult, but he will not face the death penalty.
