Coming May 2022: the return of Someone Knows Something. In Season 7, host David Ridgen and American journalist Amanda Robb investigate the 1998 murder of Dr. Barnett Slepian — Robb’s uncle — who was shot in an act of anti-abortion violence. The series explores the anti-abortion radical who was responsible for the murder and the possible links to similar attacks on Canadian doctors. With protests on the rise and debates about reproductive rights heating up in the U.S., could more violence be on the horizon?
