Farrah Fawcett & Ryan O’Neal’s Son Busted For Heroin & Meth

Ryan O'Neal and Farrah Fawcett's troubled son Redmond has been charged with two counts of possessing heroin and methamphetamine — with photos showing his shocking decline leading up to his arrest for allegedly robbing a 7-Eleven convenience store at knifepoint!

Redmond, seen here in August 2017, had seemed to be gaining weight and getting healthier after a series of arrests for drug possession over the years. His ailing father could even count on him being at his side during a hike in Los Angeles.

But by Jan. 2018, as seen here, Redmond was shockingly gaunt while taking out the trash at his father's Malibu home. By then, pals had reported that his half-sister Tatum O'Neal had already privately complained that her sickly dad was "part of the problem" after publicly stating that Redmond has "addiction problems so bad, it breaks my heart."

As earlier reported by The National ENQUIRER, Redmond had developed an addiction to the deadly hallucinogen PCP in 2015. He was caught on camera smoking what appeared to be a hand-rolled cigarette, with his half-brother Griffin going to social media to declare: “This breaks my heart…Smoking PCP in public like it ain’t no thang."

In addition to the two counts of possessing a controlled substance, 33-year-old Redmond is facing charges of second-degree robbery, assault with a deadly weapon, possession of a smoking device, and possession of an injection/ingestion device. He's pleaded not guilty, with bail placed on hold because of a probation violation involving his 2016 case. He'll remain behind bars until at least May 25, when a preliminary hearing is scheduled.
