Quinnetta Brinkley
Quinnetta Brinkley, 21, was raised by her grandmother, Opal Brinkley, in Oak Cliff, and her family describes her as strong and independent; she left a one-year-old daughter. She died on July 13, 2025, while in the custody of the Dallas County Jail, after she and three other women were taken to Parkland Hospital for a suspected fentanyl overdose. Investigators say the drugs were smuggled into the jail, and a woman has since been charged in connection with bringing them in. Her family says they have received no answers from the Dallas County Sheriff's Office, which has declined to comment while the investigation continues.

Reported by: Dallas County Sheriff's Office (the agency that held her); investigators' affidavit (outside investigators); witnesses who told investigators the women took pills.
