LAWRENCE – The trial of a West Peabody man police say shot and nearly killed a longtime friend over two years ago on Roosevelt Avenue during what prosecutors say was a drug deal gone bad is expected to begin Tuesday morning in Lawrence Superior Court.Christopher Dalomba, of 59 Harrison Ave., Peabody, is charged with armed assault with intent to murder, armed assault with intent to rob, armed assault in a dwelling and assault and battery with a dangerous weapon in the Jan. 13, 2006 shooting of 36-year-old Luigi Passanisi.Dalomba, who remains free on bail, maintains his innocence in the case.According to reports, it was shortly after 5 p.m., on Jan. 13 when Dalomba, a family friend for more than 15 years, burst into Passanisi’s home at 30 Roosevelt Ave., and shot him execution-style in the head, putting Passanisi into a coma for a month. Passanisi was also shot three times in the stomach and injured his left hand during the assault.Following the incident, Passanisi stumbled out of his house and across the street and collapsed on the porch of one of his neighbors.Dalomba fled from the scene and was on the lam for almost a year before surfacing in New York City where police picked him up on a marijuana charge in Nov. of 2006.Authorities believe Dalomba made a deal with Passanisi to deliver 30,000 Vicodin pills in exchange for $92,000 in cash, but Dalomba was deducting $5,000 from the actual cost, because Passanisi owed him that amount.When Dalomba fled out the back door of the Roosevelt Avenue home following the incident, he apparently left a shoebox full of beans, which police recovered.As authorities were investigating the shooting, they discovered hundreds of OxyContin and Vicodin pills and marijuana in various locations in Passanisi’s home.Passanisi is expected to testify at Dalomba’s trial.Judge Richard E. Welch, III, is expected to preside over the four-day jury trial.Assistant District Attorney Greg A. Friedholm is prosecuting the case and Mark Miliotis is the defense lawyer.Passanisi, 36, currently is serving a seven-year prison term for dealing drugs, and will be on probation for 10 years when he is released. He is also serving a Federal prison term of seven years, but that is running simultaneously with the other term of incarceration, instead of one after the other.
