An autopsy is scheduled today for a well-known Wood River Valley woman who was found dead in a hot tub Monday morning at Upper Board Ranch, 10 miles west of Ketchum up Warm Springs Road.
As of Tuesday afternoon, the cause of death had not been determined for 46-year-old Mila Riggio, who lived in Hailey but was staying at the ranch at the time of her death.
"There was no external trauma, so we do not believe foul play was involved," Blaine County Coroner Russell Mikel said Tuesday.
Blaine County Sheriff's Lt. Ron Taylor said Riggio's body was found at about 10:30 a.m. by a family member. She had been soaking alone in the hot tub, a converted livestock trough that is fed by natural hot water, Taylor said.
"We're just waiting for the autopsy and toxicology reports," he said.
Riggio had lived the Wood River Valley for 21 years. She was well known for her active participation in numerous community organizations and events.
Most recently, Riggio was a key player in bringing Plum Sun Valley Television to the area. She was executive producer for the station and much of the local programming.
Riggio also has helped organize the Sun Valley Spiritual Film Festival and served on the organization's board of directors.
She had been involved with the Sun Valley Ski Education Foundation and Ski magazine, producing and coordinating numerous local events.
Riggio leaves behind a teenage son and a daughter.
"She was highly involved in all their activities. She was a great mom," said longtime friend Kathy Carson. "She was a really loving spiritual person who was very excited about things. It was very fun to work with her."
Carson said she talked on the telephone with Riggio on Sunday evening before the tragic accident.
"She sounded great, like everything was going well in her life."
