Josie Harris, mother of three of Floyd Mayweather Jr.’s kids and his ex-girlfriend, died from an accidental drug overdose, as confirmed by the Los Angeles County Medical Examiner-Coroner. Her death was caused by “mixed drug toxicity,” involving fentanyl and alprazolam. Fentanyl is an opioid, while Alprazolam is known as Xanax. Harris was 40 when she was found dead on March 10 in her car at her Southern California home. Initially, the cause of death was withheld due to a law enforcement hold. Mayweather and Harris shared a volatile bond. Their tumultuous history reached a boiling point in 2010 when Harris filed domestic battery charges. The legal fallout sent the renowned boxer to prison for a brief two-month stint in 2012, marking a dark chapter in their stormy saga.
