Homicide detective sergeant Mike Carbone has confirmed a connection between the deaths of three people in Scarborough Thursday to the evacuation of a condominium on Queen’s Quay because of a suspicious package earlier in the day. The detective was feeling pressed by the need to pursue the investigation as he took time to talk to reporters on Lawndale Road in southeastern Scarborough near the scene of what has been described as three killings by crossbow. Two men and a woman are dead and fourth person injured — but details are slow to come. Carbone said police were processing the crime scene at 10 Lawndale to try to make sense of what had happened. He suggested the fourth person injured in the Lawndale incident may have serious injuries. He repeated his concern that police are “four hours into the investigation” with the intent of explaining why he does not have more information to share
