SEDONA -- Authorities looking into the deaths of two people at a Sedona-area sweat lodge are now treating the case as a homicide investigation.
Two people died and 19 nineteen people needed medical treatment after participating in a two-hour sweat-lodge ceremony Oct. 8.
The Yavapai County Sheriff's Office says those deaths were not an accident and that the organizer of the event, James Arthur Ray, is a person of interest in the case.
Investigators say Ray has not been willing to speak to them.
They served a search warrant at his corporate office in California on Wednesday.
Two people remain hospitalized Thursday. One person is listed in critical condition and the other is in good condition.
