Presley Gerber, the 27-year-old son of supermodel Cindy Crawford and businessman Rande Gerber, died at a sober living facility in September 2026. His death is being investigated as a suspected overdose. Despite his family’s resources and access to treatment, Presley had publicly expressed frustration with his psychiatric care and the number of medications he had been prescribed. His death raises questions about addiction, overprescribing, and how families can find effective help for someone they love.
In this episode of Zone 7, Sheryl McCollum welcomes her sister, board-certified psychiatric mental health nurse practitioner Shelley Halligan, to discuss the challenges of treating addiction and the risks associated with certain prescription medications. They talk about counterfeit pills, the dangers of mixing substances, and the questions patients should ask before taking new medications. For families trying to help a loved one, Shelley offers advice on researching treatment centers, explains why facilities that claim to treat everything deserve a closer look, and stresses the importance of researching treatment options.
