DOVER - A 20-year-old Barrington man previously convicted of sex crimes faces up to 67 years in prison for allegedly having photos of young girls performing a variety of sexual acts.

On Nov. 15, a Strafford County grand jury indicted Brian Tilton, who remains in custody at Strafford County Jail, on nine counts of possession of photos and digital images of sexual abuse of children on his tablet system Sept. 15, according to the indictments.

County Attorney Thomas Velardi said these are serious charges, especially since Tilton, who was in jail when the indictments were brought, was "previously convicted of sex crimes against people under 15."

Velardi said investigators are looking into the origin of the images, which could have been taken anywhere in the world. He added more charges will be filed if they come from inside the state.

All nine charges are Class A felonies, which can each yield a maximum sentence of 7-1/2 to 15 years in prison, if convicted.

Tilton is scheduled to be arraigned in Strafford County Superior Court Nov. 29 at 9 a.m.
