State Police say a man was shot to death Saturday night in the town of Rome as he was attempting a home invasion. Dead is 44 year old Christopher Dennison of Livermore Falls. Detectives said Dennison, who was wearing a ski mask and brass knuckles, broke into a mobile home on Foss Hill Lane occupied by a man and his teenage son about 8 p.m.. The homeowner, Richard Duffy, 48, shot Dennison after a brief altercation with the intruder in the living room. An autopsy by the State Medical Examiner’s Office showed Dennison died from multiple gunshot wounds. Duffy and his son were not injured and there is no indication that Duffy knew Dennison. Detectives continue to investigate the circumstances of the shooting and no one has been charged. The case will also be reviewed by the Maine Attorney General’s Office.
