Father Vows Revenge on Son's Killer Upon Prison Release

March 22, 2011— -- A small town in Rhode Island is bracing for the release of a high-profile child killer this summer who is leaving prison after serving 28 years of a 40-year sentence for the grisly murder of a neighbor's child.

It's been 36 years since John Foreman last saw his 5-year old son Jason. The boy was abducted from in front of their family home in Kingston, R.I. The boy's disappearance was a mystery for seven years until it was discovered that their teenage neighbor, Michael Woodmansee, had killed him.

But the truth behind what Woodmansee did to Jason Foreman shocked the community.

Police found Jason's body inside Woodmansee's filthy home after he confessed. Several of the boy's small bones had been shellacked and stored in the killer's bedroom.

A plea bargain spared his father and the rest of the Foreman family from learning the rest of the gruesome details of what happened to young Jason.

As part of the plea deal Woodmansee was sentenced to 40 years. Now, after 28 years of good behavior, he is leaving prison 12 years early.

His release is now set for August. And John Foreman can barely hold back.

"Initial feelings were I wanted to kill him the same way he killed my son. I wanted to hurt him bad," Foreman told "Good Morning America."

" I wanted him to suffer … And those feelings are still in my head every day, that's the problem. I can't get 'em out of my mind."

And Foreman is not the only one who opposed to Woodmansee's early release.

The town of Kingston has rallied around the grieving father, demanding the state block Woodmansee's release.

Two psychiatrists will now interview the killer in prison and read his graphic journal. What they discover could help decide if Woodmansee will instead be released to a mental hospital.

Few have read the contents of that journal, which has been locked under seal for decades. But retired detective Ronald Hawksley, the lead detective on the case that put Woodmansee behind bars 28 years ago, remembers the horrors within it.
