DOVER – A Maine man could be sentenced up to 42 years in prison for allegedly assaulting a local teenager less than half his age this summer.

On Dec. 20, a Strafford County grand jury handed down a six-count indictment against Frank McNeice, 44, of 84 Dawson St., South Berwick, Maine, including two counts of felonious sexual assault, two counts of falsifying physical evidence and two counts of witness tampering.

On Aug. 2, McNeice allegedly sexually assaulted a 15-year-old Dover girl twice, according to the indictments.

The following day, McNeice allegedly altered, destroyed, concealed or removed a futon mattress and some towels in order to impair a potential investigation. He also allegedly attempted to encourage a man and another woman to provide false information to police, according to the indictments.

Felonious sexual assault, falsifying physical evidence and witness tampering are all Class B felonies, which could each result in up to 3½ to 7 years in prison and a $4,000 fine per charge, if convicted.

McNeice is scheduled to be arraigned in Strafford County Superior Court Jan. 3 at 9 a.m.
