Four people, including a baby, were shot and killed yesterday in an apparent murder-suicide in Bayonne, police say. The Hudson County Prosecutor's Office says 28-year-old Adepso Collado fatally shot his estranged wife, 26-year-old Kenia Collado, in her Avenue A home. Jose Guzman, 31, of Ridgefield Park, and Guzman's 14-month-old son, Matthew, were also killed in the home. Guzman's relationship with the Collados remains unclear.Prosecutor Edward DeFazio says up to 20 shots were fired. He says Collado showed up at the house with a .45-caliber semi-automatic gun and three clips of ammunition. After killing Guzman and his infant son, Collado chased his wife's roommate through the small home, firing several shots and hitting the 25-year-old unidentified woman in the arm. She was hospitalized and is expected to recover.The Collados' two daughters, ages 5 and 8, were hiding in the basement and escaped unharmed. DeFazio says Collado spoke to his daughters before turning the semiautomatic handgun on himself, but he also says that the girls did not see their father take his own life. Collado's body was found downstairs and his victims were found upstairs, officials say.DeFazio says it appears the killings stemmed from an apparent domestic dispute.Officials: 4 dead, 1 hurt in apparent murder-suicide in Bayonne
