A 32-year-old Roundup man was killed when the vehicle he was traveling in plunged into the Musselshell River Thursday morning in Musselshell County.
The incident occurred at 1:25 a.m., said Montana Highway Patrol Trooper Matt Christensen.
Three men were in a small SUV at the time of the crash, which happened on Parrot Creek Road, he said.
The driver, a 21-year-old Billings man, was headed northbound on Parrot Creek Road but was unfamiliar with the roadway; the bridge is on a sharp corner, Christensen said.
As he rounded the turn, he went off the east side of the bridge.
The driver and his passenger, a Roundup man, 24, were able to get out of the vehicle. The 32-year-old, who was in the backseat, was unable to free himself.
He was brought to shore by Musselshell County Sheriff’s Deputy Nikolas Lassila and Chief Deputy Scott Johnson, who arrived on-scene moments after the crash, jumped into the river and swam to the vehicle, said Musselshell County Undersheriff Aaron Edwards.
“They took him to shore and immediately began CPR,” he said, but they could not resuscitate him. He was pronounced dead at Roundup Memorial.
The exact cause of death remains unclear, authorities said.
The other two men had minor injuries and did not require medical attention, he said.
No seat belts were worn by the occupants and it is unclear whether alcohol played a factor. All occupants had blood drawn for a toxicology screening, which will be carried out by the crime lab, said Christensen.
The crash remains under investigation.
