N.H. man arraigned in killing had violent past

The New Hampshire man accused of bludgeoning his roommate to death with a sledgehammer has a history of violent crime, records show. Peter Bartoloni, 70, was arraigned Tuesday on two counts of second-degree murder in the death last week of Robert Roderick, 56. Prosecutors said the two men had been roommates briefly before Bartoloni used a sledgehammer to kill Roderick. The Portsmouth Herald reported Tuesday that Bartoloni was convicted of rape in 1990 and assault to commit rape in 1980. The Associated Press reported in 1972 that Bartoloni was serving an 11- to 20-year sentence for armed robbery, unlawful possession of a shotgun, and escape when he stabbed another inmate at what was then called Walpole State Prison.
