COLEBROOK, N.H. (AP) — New Hampshire state troopers are gathering to remember "their fallen comrades" who were among those killed or wounded almost 20 years ago in one of the region's worst shootings.

Carl Drega, an angry loner who had repeated run-ins with local authorities killed four people, two of them state troopers, in the New Hampshire town of Colebrook on Aug. 19, 1997. He wounded four other officers and was killed in a shootout with police in Vermont.

Troopers will hold a prayer and short remembrance ceremony Friday afternoon and then lay a memorial wreath. Then at 5 p.m. runners will begin the 55 mile (88 kilometer) "relay to remember" in their honor, running from a supermarket in Colebrook, New Hampshire, to the state police barracks in Twin Mountain, New Hampshire.
