LIBBY, Mont. – Montana authorities have determined that there was no foul play involved with a fire that destroyed Libby’s last wood manufacturing plant. The Flathead Beacon reports that SK Fingerjoint, Inc. at the Kootenai Business Park burned to the ground on Nov. 5. Undersheriff Brandon Huff said his office has concluded its investigation into the fire, and at this time the insurance company and law enforcement believe the blaze was probably the result of an electrical issue.
