Donna McDonald, 37, of 38 White St., was charged with involuntary manslaughter for allegedly allowing 14-year-old Brittane Nicole Brown to take oxycodone and Xanax while she was in her care, according to court documents released Wednesday.
"We feel like her actions or lack of action led to this girl's death," said Jim Fullington, special agent in charge of Georgia Bureau of Investigation's Athens office.
Brown spent the night with friends at the home Dec. 26. Her companions found her cold and unresponsive when they tried to wake her the next day.
Toxicology reports showed she had ingested fatal levels of the pain reliever oxycodone and anti-anxiety medication alprazolam, which is sold under the trade name Xanax.
More than two months after Brown's death, police and GBI agents arrested the two adults who lived at the house - McDonald and 40-year-old Mark Ingram - and two boys, according to a statement released by the GBI and the Hoschton Police Department.
At that time, McDonald was charged with involuntary manslaughter, one felony count of contributing to the delinquency of a minor and one misdemeanor count of contributing the delinquency of a minor. She was released on $10,000 bond.
Ingram, who was arrested and released on $6,000 bond in March, is charged with single misdemeanor counts of marijuana possession, possession of drug-related objects and maintaining a disorderly house.
One of the juveniles was charged with two counts of possession of a controlled substance, while the other was charged with possession, sale or distribution of dangerous drugs, investigators said.
Neither Ingram nor the two boys face felony charges.
However, when grand jurors met this month they indicted McDonald on an additional involuntary manslaughter charge, felony contributing to the delinquency of a minor and reckless conduct charges, as well.
McDonald faces three counts of contributing to the delinquency of a minor - one for allowing Brown to take oxycodone in her house, one for allowing her to take Xanax and one for allowing a male juvenile to take oxycodone while at her house.
Two of the contributing charges are felonies because Brown died.
She's also charged with two counts of reckless conduct because, prosecutors say, she "failed to properly control the controlled substances in her house."
McDonald faces two counts of involuntary manslaughter because authorities say she contributed to Brown's death by allowing her use the drugs at her home and by failing to secure the controlled substances inside her house.
No court dates have been set in McDonald's case.
