The Special Investigations Unit is clearing a Thunder Bay Police Officer of any wrong doing in the death of a 67 year old man on Northern Avenue over the May long weekend. A police officer was following a reported stolen vehicle and a short distance later that vehicle crashed into Martin John Amos' car. SIU Spokesperson Monica Hudon says the police officer was following the stolen car but didn't use his lights or sirens to try and get the vehicle to pull over. Hudon says the driver of the stolen car lost control of it while trying to get away from the police.
