RUPERT — A Washington state man is charged with vehicular manslaughter after a crash last April that killed his passenger, 17-year-old Alex Anthony Stone.

Stephen Fred Afuvai, 19, of Puyallup, Wash., was charged with misdemeanor vehicular manslaughter after the Idaho State Police, which investigated the April 13 crash on Interstate 84 near milepost 201, said he failed to stay in his lane of traffic after he fell asleep at the wheel.


Troopers estimated that he was traveling at a speed of more than 89 mph in a posted speed zone of 80 mph.

Officers said Afuvai was eastbound in a 2000 Volkswagen Jetta when he fell asleep and went off the left shoulder of the road. When he heard the sound of the rumble strip he reentered the road and over corrected entering the median and rolling the vehicle, which came to rest in the westbound lane of traffic.

Stone was thrown from the car and was lying in the westbound lane of traffic.

One passenger, who was a minor, was flown to Portneuf Medical Center in Pocatello. Afuvai and a third minor passenger were taken by ambulance to Minidoka Memorial Hospital in Rupert.

None of the occupants in the Jetta were wearing seat belts.

Afuvai was arraigned in Minidoka County Magistrate Court on the charge on Jan. 26 after a warrant was issued for his arrest. A pre-trial hearing is set at 11 a.m. on Feb. 14 in Minidoka County Magistrate Court.
