ANCHORAGE, Alaska - A 22-year-old man died after exchanging gunfire with an Alaska state trooper during a traffic stop near Wasilla early Saturday, authorities said.
The incident began when the trooper pulled over a vehicle carrying three people just past 4 a.m. While the trooper was talking to a passenger, the driver - Nicholas Leo Frazier of Anchorage - stepped out and shot at the officer, Alaska State Troopers spokeswoman Megan Peters said.
The trooper suffered non-life threatening injuries around his head, Peters said.
"Despite his injury, the trooper pulled out his gun and exchanged fire," she said.
Frazier took the wounded trooper's vehicle and drove away. He was found dead inside the vehicle about a mile down the road.
Peters couldn't confirm that the man died of wounds suffered in the exchange of fire. She said authorities were waiting for an autopsy tentatively scheduled for Monday.
The trooper's name will be release d in three days, per the agency's policy. He was released from a hospital a few hours after the shooting.
The two other people in the vehicle were questioned and released, Peters said.
