TUOLUMNE COUNTY, CA - A family rafting adventure on the Tuolumne River ended in tragedy Tuesday afternoon.
Sgt. Jeff Wilson with the Tuolumne County Sheriff's Office said Mariati Tani, 41, of Sausalito, was on a guided raft with relatives when their raft encountered an unexpected Class 5* rapid and became stuck on a rock. The impact ejected most of Tani's family from the raft but she was trapped under the raft in the water about approximately 10 minutes before one of the guides could free her.
Wilson said efforts to revive Tani were unsuccessful.
Earlier in the day, sheriff's deputies and detectives were called to the discovery of a body in Pine Mountain Lake near a swimming platform off of Dunn Beach.
Wilson said the victim was identified as Ronald Temporosa, 28, of San Lorenzo. Investigators learned he had been vacationing in the area with a friend and had told the friend he planned to go for a morning swim.
An autopsy was to be conducted later on Wednesday but the preliminary investigation suggests Temporosa's death was an accidental drowning, Wilson said.
*A Class 5 river is described in the International Scale of River Safety as extremely difficult with long and violent rapids, following each other almost without interruption; riverbed extremely obstructed; big drops; violent current; very steep gradient.
