"After the first round when the door opened and people came out, I was shocked. I was shocked at the condition of the people that came out. A girl comes out, and she was hysterical. She was crying, telling me, 'This is bad. This is bad. I don't like this. I want to go back to the way I was. Please, please. I don't like this. This is bad.'"
As the ceremony went on, the damage got worse. Martin claims there was no paid medical staff on site.
"I had another guy come out, and he was screaming at the top of his lungs. 'I don't want to die! Please don't let me die! Please! Please save me! I'm dying! I'm dying!' He was screaming so loud, and … I'm doing everything I can to put water on people and calm their -- their -- the heat, you know, just put water on them to bring the heat down, put towels on them, trying to warm them up, give them electrolyte water, do all the things that I was told that I would have to do, but amplify it by, you know, 1,000 percent, because now I was dealing with people in trances and saying they were dying and they -- their arm skin was gone."
Martin said she wanted to call for help, but Ray's staffers told her no.
"They told me that that wasn't something that would be done, because in the past, 911 had been called, and James got very, very angry at the person who called 911, so that had already been quashed. So I was in the mode of taking care of people," she said.
What's more, Martin said she was also told not to even look alarmed. "And they told me, 'Melinda, get the look off of your face, because you're scaring people. You're going to make people think this isn't normal,'" she said.
Martin said that while people were being dragged out from the tent in front of him, Ray made no mention of stopping the ceremony. She said she was on the side of the tent when Ray exited the sweat lodge and saw the pandemonium outside.
"He came out, and he stretched his arms up, and everybody hosed him off, and he's like, 'Hey, thanks,'" Martin recalled. "I just stopped and I said, 'How can you walk out of there with all of these people are down and they're -- they looked near death, and you guys can walk out there looking like you just spent the day in the spa?' It was incredible to me."
"When he walked out and he made a right-hand turn as he went to go sit down and get a drink of water, the guy who had been screaming at me, saying he didn't want do, 'I'm dying! I'm dying! Please don't let me die!' James walked by him, and he goes, 'Hey, I died. I died, and I came back to life.' And James was like, 'Yeah, man,' gave him a high-five. You know, I think James didn't really realize to what extent all this stuff was going on," she said.
As Martin performed CPR on a dying woman, she said her boss simply stared.
"I look up, and he's standing right over my head watching. He's watching from a stand-up position. He didn't offer to help. He didn't say anything, nothing at all," Martin told "Nightline." "And he was like kind of just looking around. And I'm sure he was shocked, but so was I, but that didn't stop me from getting down on the ground and, you know, working and trying to get people back to life."
In response to Martin's comments, Ray's company said in a statement to ABC News that Ray tried to help, according to the information the company collected from employees and event participants during its private investigation:
