UPDATE: The Catoosa County Sheriff's Office is investigating it's first murder of the year.
Brian Davenport is charged with the murder of the woman he called his fiance, Deborah Abney, 46. Abney's body was found inside of a parked car. Her death was believed to be a suicide, until Davenport's story began to unravel.
Davenport is now behind bars, charged with felony murder. Deputies believe he shot the mother of his kids in the back of the head after a court hearing on Friday.
"The initial call was that it was a suicide of a young lady who had shot herself in the head," said Sheriff Gary Sisk, Catoosa County Sheriff's Dept.
Deputies found Deborah Abney slumped over in the passenger seat of a car parked in the 2100 block of Taylors Ridge Road.
The area is isolated, surrounded mostly by woods. Davenport told responding deputies the property belonged to a friend and he and Abney were there to talk and eat sandwiches.
"We're still reaching out talking to everyone trying to really find out whats been going on with these individuals over the last several months, I know that afternoon or that day they did have a court hearing," said Sheriff Sisk.
Deputies say the court hearing didn't go well, family friends say the couple lost custody of their two daughters.While Davenport was being interviewed, investigators found inconsistencies in his story.
"Our crime scene technician continued to process the scene there and he had found evidence that the firearm had been moved," said Sheriff Sisk.
Sheriff Sisk says that Davenport admitted to moving the gun but not to shooting Abney. He was then charged with making false statements and tampering with evidence.
"He did not call 911," said Sheriff Sisk.
Sheriff Sisk says Davenport called his mother instead, she then called the property owner who called 911, 10-15 minutes after the gun went off. Abney's autopsy ruled her death a homicide.
"It was determined that miss Abney was shot in the back of the head," said Sisk.
Davenport is now charged with felony murder, 2 counts of giving false information and tampering with evidence. He's being held in Catoosa County Jail without bond.
Sisk said Davenport has a history of domestic violence. This marks the county's first homicide of 2016.
