(AP) — A Massachusetts judge has ruled that a man convicted of killing a pregnant woman and her two young children 30 years ago must serve at least 45 years in prison. Daniel LaPlante was sentenced to three consecutive life sentences without parole for fatally shooting 33-year-old Priscilla Gustafson and drowning 7-year-old Abigail and 5-year-old William in their Townsend home in 1987.
