Four people were transported to St. Luke's Wood River Medical Center following a near head-on collision south of Bellevue late Tuesday afternoon.
Blaine County Sheriff's Lt. Ron Taylor said three of the victims were treated and released later Tuesday. An elderly man was held overnight and released Wednesday.
The mishap occurred shortly after 4:30 p.m. one mile south of Bellevue on state Highway 75. Taylor said a 1998 Ford motor home driven by Marvin Orvik, 82, of Carson City, Nev., was northbound when Orvik "fell asleep at the wheel" and drifted into the southbound lane, sideswiping a 1997 Ford F250 pickup driven by Daniel Tellez, 26, of Jerome.
"Daniel tried to avoid him, but it was impossible because Orvik just kept coming toward him," Taylor said.
Three Wood River Fire and Rescue ambulances transported Orvik, Tellez and two passengers in the Tellez vehicle to the hospital south of Ketchum. The passengers were identified as Jose Silva Sr., 46, and Jose Silva Jr., 15.
Taylor said the accident could have been much worse.
Both vehicles were totaled.
Taylor said the accident was still being investigated Thursday. No citations had been issued.
