REDDING, Calif. -- A Port Angeles, Wash., firefighter was killed Friday afternoon fighting a fire in northern California.

Andrew Palmer, 18, was an Olympic National Park Service firefighter assigned to the Iron Complex of fires on the Shasta-Trinity National Forest.

Mike Odle, of the Shasta-Trinity National Forest, said Palmer "suffered injuries from what sounds like an incident with a tree." Investigators are looking into the circumstances surrounding Palmer's death.

Palmer was transported by a U.S. Coast Guard helicopter to a hospital in Redding, Calif., to be treated for multiple injuries. He was pronounced dead while en route to the hospital 50 miles away, Odle said.

"Andy was a dedicated and energetic firefighter who loved his job. We are all very sad, and our thoughts are with his family and the rest of the firefighters on this fire,” said Olympic National Park superintendent Karen Gustin.

Palmer had just graduated from Port Townsend High School.

Palmer was assigned to one of the 28 fires that started on June 21st after a lightning storm. Currently, the fire has burned 7,237 acres and is only 63 percent contained, Odle said.

A fund will be established by the Wildland Firefighter Foundation in Andrew's name. The foundation is online at wfffoundation.org and can be contacted by calling 877-336-2950.
