CRANSTON, RI (FOX 25 / MyFoxBoston.com) - A man who killed a 5-year-old boy and allegedly ate him is set to be freed from a Rhode Island jail in August. Michael Woodmansee, 16-years-old at the time, kidnapped and killed Jason Foreman in 1975. Foreman was presumed to be missing until 1982 when Woodmansee tried to lure another boy into his home. The boy escaped and police began to question Woodmansee about Foreman's disappearance. They found Jason Foreman's skull and bones, which had been shellacked, on Woodmansee's dresser along with a journal which detailed the gruesome killing. Woodmansee pleaded guilty to second-degree murder in 1983 and was sentenced to 40-years in jail. This was part of a plea bargain meant to spare the Foreman family from hearing the details of their son's death. Woodmansee is getting 12 years shaved off of his sentence for good behavior in prison. Jason's father, John, believes that Woodmansee was a cannibal that ate his son's flesh. Speaking to WPRO's John DePetro John Foreman said, "I do intend, if this man is released anywhere in my vicinity, or if I can find him after the fact, I do intend to kill this man.
