A woman has been charged with felony murder, months after the body of her 83-year-old mother was found decomposing in a bedroom of their Forsyth County home, officials said.

Chamblee police arrested 54-year-old Amalia Ramirez on Tuesday, according to a news release from the Forsyth County Sheriff’s Office.

Ramirez was the only caregiver for her mother, Himilce Ramirez, sheriff’s office spokesman Cpl. Doug Rainwater said. The two had been living together in a house on Brindle Drive in Cumming for about four years, he said.

Deputies were initially sent to the home Dec. 6, 2018, after someone called and reported that Amalia Ramirez had threatened suicide, Rainwater said. When deputies arrived at the house, they noticed a “foul smell” coming from the bedroom where Ramirez’s mother was located.

Ramirez was taken to Northside Hospital-Forsyth for an evaluation due to the suicide report, Rainwater said. Her mother’s body was taken for an autopsy by the GBI.

Rainwater said authorities found the body was in the advanced stages of decomposition based on its condition. It likely had been in the bedroom for days, he said.

Amalia Ramirez was initially arrested on charges of elderly neglect and exploitation/intimidation of the elderly. She was booked into the Forsyth County Jail on Dec. 6 and released more than three weeks later after posting a $11,240 bond.

An autopsy by the GBI determined that the manner of death for Ramirez’s mother was homicide by neglect. The sheriff’s office obtained a murder warrant for Ramirez on April 30, Rainwater said. She is in the Forsyth County Jail without bond.
