A grand jury Nov. 15 determined 15-year-old Gregory Ramos — accused of strangling to death his mother, Gale Cleavenger, in their DeBary home and, with the help of two friends, burying her under a fire pit at a nearby church — will be charged as an adult with first-degree murder.

State Attorney R.J. Larizza announced the decision at a press conference at the Volusia County Courthouse in DeLand.

Ramos is also charged with abuse of a dead body and tampering with a crime scene. The Sheriff’s Office said the trio staged a burglary to try to cover up the crime.

Ramos’ 17-year-old friends, Brian Porras and Dylan Ceglarek, also will be charged as adults on a charge of accessory after the fact, which is a first-degree felony.

Because Ramos is a juvenile, the death penalty is not on the table.

The trio appeared in court for the first time as adults Nov. 16.

Ramos, who confessed to deputies, was denied bond. He is being represented by Public Defender Matthew Phillips.

Ramos was also ordered by the court not to try to contact Danny Cleavenger, his stepfather. He already had a no-contact order for the next-of-kin to the victim, as well as his co-defendants, but had apparently repeatedly attempted to phone Mr. Cleavenger.

Porras, who has no criminal history, has a $100,000 bond.

Ceglarek was denied bond because of a history of possible  mental illness.
