Killing of wife
Robb pleaded guilty in November 2007 to voluntary manslaughter in the high-profile death of his wife, Ellen Gregory Robb. She had been bludgeoned to death with a chin-up bar. Her death occurred during a December 22, 2006, argument over the couple's divorce and the plans for their home in Wayne, Pennsylvania. Robb pleaded guilty on November 26, 2007, and resigned from the university, where he had been on leave since his arrest in January 2007. Robb was sentenced on November 19, 2008, to a 5- to 10-year prison term, though the prosecutor asked for a sentence of 10 to 20 years.  He was denied parole in January 2013.The case was prosecuted by District Attorney (later County Commissioner specially appointed as prosecutor) Bruce L. Castor, Jr. who commented the oft quoted line "Professor Robb may be smarter than us, but he still is an amateur killer and we are professional catchers of killers."
