KNOXVILLE, Tenn. (AP) — An East Tennessee woman has been charged with murder in the overdose death of her infant daughter.

Media report 31-year-old Heather Renee Keylon of Oak Ridge was arrested Saturday and booked in the Knox County Jail on a $1 million bond. According to a grand jury indictment on March 8, Keylon is also charged with abuse and neglect in the April 2015 death of Skylar Brewer.

An autopsy report determined the cause of death was an overdose, but it did not list a manner of death.

A toxicology report said the child had Suboxone, a drug used to treat opiate addiction, in her bloodstream when she died.

It wasn't immediately clear whether Keylon has an attorney.
