HARRISBURG, Pa. (CBS) — After a meeting with the chairman of the Pennsylvania Board of Probation and Parole, the brother of Ellen Gregory-Robb says he’s optimistic that his sister’s killer will not go free next Monday as planned.

The board has decided to release Rafael Robb after having served only half of his 5-to-10 year manslaughter sentence. Robb pled guilty to bludgeoning his wife Ellen to death in their Upper Merion home. Ellen Robb’s brother, Gary Gregory, said the meeting he and his brother had with the chairman of the Board of Probation and Parole Tuesday was mostly to discuss process, but that he’s confident that the board now has additional information that makes the case for a revocation of Rafael Robb’s parole.

“The parole board is now firmly and fully equipped to review this, do the right thing, and keep Rafael Robb behind bars,” Gregory says.

Included in that new information is a letter from the judge who presided over Robb’s trial. Calling Rafael Robb a “highly manipulative man,” the judge says this is the first time he’s ever raised a written objection to the board about an inmate.
