HOULTON — Flags are flying at half-staff as a Marine killed in Afghanistan is being remembered at a memorial service in northern Maine.

A service is being held Thursday at Houlton High School for 1st Lt. James Zimmerman, who died Nov. 2 of injuries suffered in combat operations. The 25-year-old Zimmerman was a platoon commander out of Camp Lejeune, N.C.

Zimmerman grew up in Smyrna, about 10 miles outside of Houlton, and graduated from Greater Houlton Christian Academy.

Gov. John Baldacci has directed that U.S. and state of Maine flags fly at half-staff from sunrise to sunset in Zimmerman’s honor.
