WARNING: This episode deals with sexual assault

Rick Boguski's brother Darryl has cerebral palsy, is blind and has autism. And on April 20, Darryl's 62nd birthday, Rick was told by the RCMP that his brother had been identified as one of five victims of sexual assault that allegedly occurred at Shepherd's Villa, a group home for the severely disabled in Hepburn, Sask.

The suspect, Brent Gabona, had cared for Darryl at the home for years.

Since then, Gabona, 52, has been charged with five counts of sexual assault and three of sexual exploitation of a person with a disability — which court records say occurred between 1992 and 2006. But other families who had loved ones in his care wonder if there may be more victims, and are pressing the RCMP to dig deeper.

Today on Front Burner, CBC's Jorge Barrera shares what he learned after his conversations with Rick — and with Gabona himself.
