MARION COUNTY, Fla. – Two Marion County parents are in custody after their 2-year-old daughter was found dead from a fentanyl overdose, according to authorities.

Marion County sheriff’s deputies responded to a call in June from Umatilla about an unresponsive toddler. When they arrived at the home, they found Miya Tierney lying in her bed, sheriff’s officials said. She was taken to a nearby hospital where she was pronounced dead, deputies said.

According to the sheriff’s report, Miya’s parents, Joseph Tierney and Jalynn Davis, both 35, said they put her to bed and left her alone for 30 minutes. When they returned, they found her unresponsive and called 911, the report says.

In August, the Marion County medical examiner determined Miya’s cause of death to be fentanyl toxicity.

MCSO said its investigation found that Davis, Miya’s mother, was selling fentanyl, and her father, Tierney, was an active user.

The two were arrested on Tuesday, Nov. 2, on charges of aggravated manslaughter of a child. They are both being held without bond.
