Valery Fabrikant, convicted of killing four Concordia University engineers in a 1992 campus shooting, is continuing to pursue his ongoing lawsuit against his former colleagues. Fabrikant is seeking $600,000 in damages over allegations other professors unfairly profited from his work. Fabrikant had been in court in 2007, but the case was tossed out. An appeal court later ruled that that was a mistake. One of the witnesses in court on Monday was former Concordia professor, Tom Sankar. “Fabrikant asked Sankar to explain why the number of scientific papers he published had doubled after Fabrikant was hired by the university,” the CBC reported.
