Police in Volusia County, Fla., have charged Cleavenger's 15-year-old son, Gregory Logan Ramos, with strangling his mother in the early hours of Friday after the pair argued about a D grade he'd gotten in school.
Early Friday, the teen put his mother's body in a wheelbarrow in order to load her into a van, which he drove to River City Church, approximately one mile from the home, police said.
The Sheriff told reporters they believe that over the course of two days, the teen killed his mother then enlisted the help of two friends to help him dispose of her body. The two other teens are facing undisclosed criminal charges, the sheriff's office said.
Detectives responding to that call around 3:52 p.m. began investigating what initially was reported as a burglary, supposedly discovered by Ramos after he came home from school.
The father was on a business trip in Seattle, WA, during the incident.More news: Promising rugby player (28) dies after eating slug on dare
"These guys helped him bury his mother back here", Chitwood said.
However the details did not add up after Cleavenger's architect firm said she didn't show up to work that morning.
Chitwood told the Daytona Beach News-Journal that the boys chose the pit because the soil was loose and could be easily dug up. "There was nothing at all like that", Chitwood said. The next morning, the suspect allegedly went to school, returned home, then called 911 to report his mother missing. "By all accounts she was an awesome human being", Chitwood said. There, he buried the body beneath a fire pit.
"The deputies and detectives who worked through the night and into the morning gave this case absolutely everything they had, and I hope the family knows that Gail has all of us fighting for justice for her", Chitwood said.
"I have a feeling this is a case we'll be hearing about for years to come", he said. Chitwood said Ramos used his knowledge of crime scene analysis to disguise the scene where he had buried his mother's body.
