CANADIAN — After the death of 20-year-old Stacy Dawn Murphy at a Church of Scientology-backed drug rehab program in Pittsburg County, the state enacted a new law to provide more oversight of drug and alcohol rehabilitation centers.

However, Narconon Arrowhead, where Murphy and three other clients died, continues to operate legally because the law allows only limited supervision from the Oklahoma Department of Mental Health and Substance Abuse Services.

“I am very surprised they are still open, I sure am,” said Gary Richardson, a Tulsa attorney who represents former Narconon Arrowhead clients and their parents, including Murphy’s parents, in nearly a dozen lawsuits against Narconon.

Murphy, a former waitress from Owasso, sought treatment for heroin addiction at Narconon Arrowhead. She died of an accidental drug overdose at the program in July 2012. Her parents are suing for negligence and wrongful death. The case is set for trial later this year in Pittsburg County District Court at McAlester.
