SOLDOTNA -- An Alaska state trooper is in fair condition at Central Peninsula Hospital on the Kenai Peninsula after being injured in a collision.

KSRM-AM radio reports that trooper Thad Hamilton was responding to a domestic violence call in Nikiski when his patrol vehicle collided with a truck on Wednesday night. Trooper spokeswoman Megan Peters says another trooper responding to the same domestic violence call came upon the accident moments after it occurred.

Troopers are not releasing the name of the truck driver, or the extent of his injuries, as they investigate. But Kenai Fire Chief Mike Tilly told KSRM that the man is a Kenai resident in his early 40s.
