UPDATE:Death on the Yellowstone

What started as a Sunday float trip down the Yellowstone River with two close friends ended in tragedy when the raft flipped and one man drown.
Lorne Speakerworth, a 47-old-year-old man from the Worden and Lockwood areas, died of an accidental drowning, said Stillwater County Sheriff Cliff Brophy.
Speakerworth and a “lifelong friend” were floating when their raft overturned just above the main bridge when they went through a section of whitewater.
The friend called 911 at 3:45 p.m. and reported that he saw Speakerworth floating under the bridge for a time but then lost sight of him. Speakerworth was not wearing a life vest.
Approximately 30 minutes later a second 911 call was made from someone who found Speakerworth one mile below Columbus, said Brophy. Columbus Fire Rescue and Columbus police retrieved Speakerworth from the river and initially felt a “very faint pulse.” CPR was performed but he was tragically pronounced deceased shortly after, said Brophy.
The surviving victim suffered minor injuries, mostly scrapes to extremities, and was taken to the Stillwater Billings Clinic by ambulance.
Columbus police, Columbus Fire Rescue, Search and Rescue, Fish, Wildlife & Parks and the sheriff’s office responded. FWP will conduct the death on a waterway investigation, per U.S. Coast Guard regulations.
Brophy said an unrelated water call in the same area was reported at 3:30 p.m. which “added to the confusion while responding to the fatality.” Everyone involved in that incident was fine, said Brophy.
Brophy stressed the importance of wearing a life vest of some type for everyone who plans to spend time on the water.
There have already been 18 deaths in Stillwater County so far this year into which coroner inquiries have been conducted.
The average is between 20 and 25, said Brophy.
