BANGOR - A Bangor man convicted in the beating and suffocation of a friend with cerebral palsy will spend the rest of his life behind bars.

A judge imposed a life prison sentence Friday on 37-year-old Peter Tuller, who was convicted of murdering 47-year-old Michael Demmons in June 2006.

Demmons' body was found hog-tied with plastic trash bags over his head in an apartment he was sharing with a woman described as Tuller's ex-girlfriend. The state medical examiner testified that Demmons' skull was fractured more than 10 times and that 15 of his ribs were fractured two to four times each.

Police found Tuller hiding under a bed in the night of the attack.
