Yavapai County Sheriff Steve Waugh said the deaths of Kirby Brown, 38, of Westtown N.Y. and James Shore, 40, of Milwaukee were not accidental.
"A combination of circumstances led to the deaths," Waugh told reporters. "Whether or not we can prove a criminal case, that has yet to be determined."
Waugh said investigators are looking at the way the sweat lodge was built, the fact that people had fallen ill at previous sweat ceremonies led by Ray, and questionable medical care on site. Ray is the primary focus of the probe but others also are being investigated, the sheriff said.
Police would not say what, if anything, was found in executing the search warrant.
Asked why the deaths have been classified as homicides and the investigation upgraded, Waugh said, "We believe there are indications that it was not accidental, and ... we feel that there should be some culpability on some individuals."
Those individuals could include Ray and possibly others, he said.
Let's hope Ray ends up behind bars with his career and his New Age empire destroyed. But only if he's found guilty, of course.
