Montgomery County's prosecutor and a pair of state representatives have called on state officials to reconsider the parole of convicted killer Rafael Robb.

District Attorney Risa Vetri Ferman and Pa. Reps. Mike Vereb and Todd Stephens held a news conference in Norristown on Friday.

They urged the Pennsylvania Board of Probation and Parole to convene a new parole hearing to listen to the testimony of Ellen Robb's family.

Rafael Robb, a former University of Pennsylvania professor, beat his wife, Ellen, to death as she wrapped Christmas presents inside their home in Upper Merion Township in December 2006.

Robb pleaded guilty to voluntary manslaughter in 2007 and was sentenced to five to 10 years in prison, but he is now set to be released on parole later this month.

"The unspeakably brutal killing of Ellen Robb stands out as the worst manslaughter case I have ever seen," said Ferman. "Every sentence in Pennsylvania has a minimum and a maximum. The maximum is reserved for the worst offenders. Rafael Robb is just that."

Gary Gregory, brother of Ellen Robb, took part in the news conference.
