Keylon was out on bond when authorities arrested her last month in the motel at 5100 Family Inn Drive in North Knoxville.

A background check revealed she was awaiting trial for the alleged murder of her nearly 3-month-old daughter Skylar Brewer in April 2015.

A toxicology report says the baby had suboxone in her blood when she died. Suboxone is typically used to treat patients who are dependent on opiates.

According to an autopsy report, the baby was born drug dependent because of her mother's addiction during pregnancy.

Keylon faces trial in January 2018 on counts that include felony murder, aggravated child abuse and aggravated child neglect.
