A woman taken to hospital with multiple organ failure after attending a spiritual retreat in Arizona has died.
Forty-nine-year-old Liz Neuman was one of 21 people taken to hospital after the sauna-like experience on 9 October.
It brings the total number of deaths from the event, run by self-help expert James Ray, to three.
The deaths at the Angel Valley Retreat Center, 115 miles north of Phoenix, are being treated as homicides, but no charges have been laid.
Emergency services were called to the sweat lodge after some of the 50 people at the event reported they were having difficulty breathing.
Those taken to hospital were said to have illnesses ranging from dehydration to kidney failure.
