A wreck killed an Anchorage man and severely injured the driver early Friday on the Glenn Highway near Chickaloon, according to Alaska State Troopers.

Anchorage resident Yong Lee, 57, was driving a 2004 Chevrolet Suburban southbound on the Glenn when he fell asleep about 7 a.m. Friday, troopers said in a written statement. The Suburban first went into the ditch on the right side near Mile 74, then veered back onto the highway, skidded, rolled and landed in the opposite ditch, troopers said.

Young Yoon, 66 and also an Anchorage resident, had been lying down in the back of the Suburban and was killed when he was ejected from the vehicle, troopers said. Lee, the driver, was seriously injured. Another man, Chang Yoon, 54, suffered minor injuries, troopers said.

The men are all related, said troopers spokeswoman Beth Ipsen. They were returning to Anchorage from a fishing trip to the Chulitna River, she said.

A helicopter flew Lee to a hospital in Wasilla, troopers said. A medical examiner will conduct an autopsy on the elder Yoon, the only one in the wreck not wearing a seat belt, troopers said.
