OKLAHOMA CITY - Family members of a woman who recently died at a Scientology drug rehab center file a lawsuit against Narconon Arrowhead, this as a former employee comes to Oklahoma, to protest the facility.

Hillary Holton entered in Narconon's Arrowhead facility for help with her prescription drug addiction in April.  Less than 48 hours later she was dead. In a lawsuit filed Thursday, attorneys say Holton had a medical condition, but employees at Narconon didn't provide her with the care, or medication she needed.

"I would have died in there, just like they did," said Colin Henderson.

Henderson was a patient at Narconon Arrowhead back in 2007. He says he had the same problem with his heart medicine.

He left after just weeks, but has been working to shut down the facility ever since 2009. That was about the same time that David Love Edgar left Narconon's Quebec facility.  He was not only a patient but employee.

"It was hell, it really was.  I saw people taken away in ambulances," said Edgar.

The two men met for the first time Thursday. They are in Oklahoma for this weekend's protest to bring awareness to their cause.

"If they don't shut it down, in my opinion, I think they're putting their political careers on the line, because if another person dies, you're not just going to have 100 people come from other countries, but from around the world," said Edgar.

Love also brought with him piles of documents he will share with Oklahoma Sen. Tom Ivester, Investor has said he wants stricter regulations of Narconon Arrowhead. The documents detail how officials in Quebec were able to force the facility there to close.

"If our state doesn't move quick enough, somebody else is going to die," said Henderson. 

Love and Henderson believe if Narconon here in Oklahoma is shut down, facilities across the United States will follow. The protest is Saturday at 1 p.m. in McAlester.
