Former UPenn professor who beat wife to death due to be paroled after 5 years in prison

(CBS/AP) NORRISTOWN, Pa. - A former Ivy League professor who pleaded guilty to beating his wife to death as she wrapped Christmas presents is set to be paroled.

Rafael Robb was sentenced in December 2008 to 5 to 10 years in prison in the December 2006 death of his wife, Ellen, in suburban Philadelphia. Robb pleaded guilty to voluntary manslaughter in 2007.

Montgomery County District Attorney Risa Vetri Ferman says she recently learned that Robb is due to be released on parole later this month. She says she's asked the state parole board to reconsider the decision.

Ferman says she thinks the board didn't consider all issues surrounding the case.

Robb, who was once a tenured economics professor at the University of Pennsylvania, said in court that the killing happened in "a moment of madness."
