Forty-nine-year-old John James "J.J." Paulsen was sentenced Friday in Hamilton Superior Court on charges of voluntary manslaughter, neglect of a dependent and moving a body from the scene of death.
Prosecutors had dropped a murder charge as part of a plea agreement.
Police say the body of Leanne Serrano-Paulsen was found hidden in the attic of their posh house in Carmel in April 2007. They say the couple's 16-month-old son, Christopher, was found unharmed in a crib.
Police has said Serrano-Paulsen previously called authorities after she was beaten by her husband.
