In June 1901, tragedy struck one of Montreal’s wealthiest families when Ada Maria Mills Redpath and her son Clifford were found dead in their lavish mansion. Initial reports suggested Clifford, suffering from ill health, may have shot his mother before turning the gun on himself, but inconsistencies in witness accounts and the family’s social standing fueled speculation of a deeper mystery. Police investigations were brief and the case was quickly closed, leaving lingering doubts about what truly happened behind the Redpaths’ gilded doors. More than a century later, the Redpath Mansion Murders remain an unsettling blend of privilege, secrecy, and unanswered questions in Canadian true-crime history.
