Roger L. Brown died in a crash off of Bogus Basin Road Sunday afternoon, according to Idaho State Police.

The 50-year-old Boise man was the only person in the vehicle, which rolled 225 feet down a steep embankment. The man was wearing a seatbelt, but the force of the crash ejected him about 20 feet from the vehicle, said Boise County Chief Deputy Coroner Mike Johnson.

Alcohol was a factor in the crash, according to Idaho State Police. Johnson said blood tests revealed that Brown had a .23 blood alcohol content (bac) percentage level at the time of the crash. The legal bac limit for driving in Idaho is .08.

The report of a vehicle over a cliff off of Bogus Basin Road came into Ada County Dispatch at 2:20 p.m., a dispatcher said. The accident occurred about 10.5 miles up Bogus Basin Road from Boise.

Brown was driving a 1979 Porsche 930, police said.

Ada County Paramedic Clinton Wolf said the car was traveling down the mountain before the crash. The vehicle crossed the oncoming traffic lane, went off the road and down a steep hillside.

Because of the steep hillside, the all-volunteer Idaho Mountain Search & Rescue Unit was dispatched to the scene to help recover the body.

Brown was a local attorney who worked for an insurance company at the time of his death.

Johnson said the cause of death blunt force trauma to the head and chest, and no autopsy will be done.
