Police say Walsh, who was known as Tony to family and friends, left a home in Crowes Mills, NS, on Aug. 23, 2019. He was last heard at around 1:20 p.m. of that day. His disappearance was initially investigated as a missing person. However, in December 2020, police said they were treating the case as homicide after receiving new information. The investigation led police to arrest a 56-year-old Londonderry, NS, on Thursday. John Alfred Cook has been charged with first-degree murder in Walsh’s death. Investigators also found human remains Thursday in the Londonderry area. Police say they believe the remains belong to Walsh, based on data and information gathered by investigators. Cook has been remanded in custody and is due to appear in Trouro District Court on August 2. This is a story that unfolds. He will be informed.
