Canada's Supreme Court on Friday ordered the estate files of a slain Canadian pharmaceutical billionaire couple to be unsealed, reasserting the principle that court proceedings should be public in a case led by the Toronto Star newspaper. Barry Sherman and his wife Honey were found hanging by belts from a railing at their Toronto mansion in late 2017, a crime police are investigating as a targeted double murder. Trustees were appointed to handle the couple's affairs, and the estate files were sealed by a judge, denying Toronto Star reporter Kevin Donovan access to them and setting in motion a three-year court battle that ended on Friday.
