Pahrump radio personality Art Bell died of an accidental overdose from a cocktail of prescription drugs, the Clark County coroner’s office said. Bell died April 13 in a bedroom of his Pahrump home at age 72. The coroner’s office determined he had four prescription medications in his system: the opioid oxycodone, the analgesic hydrocodone, diazepam, often marketed as Valium, and carisoprodol, a muscle-relaxant. Bell was known as the late-night host, engineer and producer of the show “Coast to Coast AM.”
