Speed and alcohol appear to have been factors in a motorcycle crash that killed a Maine man, according to New Hampshire State Police.
The crash happened Monday evening on Interstate 93 in Thornton.
Police say 54-year-old Roy Voisine, of Chester, Maine, was going south when he lost control of the motorcycle, went off the road and hit a highway sign. A witness reported seeing the motorcycle speeding erratically before the crash.
Anyone with further information is asked to call state police.
