Should have given a thumbs up to Nancy for all your smarts and connecting information to solve crimes in your numerous cases. Great work and ingenious questioning the facts that solve these cases with new techniques.

Strange that I saw this episode. Similar incident happened in Edmonton AB Canada where a person threw a pumpkin (had to have been before or at Halloween) off bridge over Quesnell Freeway and injured / killed driver of a vehicle. Heard it on local news.  Some time later, I saw a pumpkin thrown through a window of a PARKED car in alley some 5 blocks from where incident occurred = perhaps the  same one as incident??? OR done like copycat OR someone pulling same prank.  I see this "LORRY" word means TRUCK there, episode is of a brick incident that happened there in Camberly, England which is far from Edmonton in Canada, BUT lets say a cousin or friend here conversed / joked with a friend / cousin there and used a pumpkin here vs a brick there when the two were talking on a phone call. YOU NEVER KNOW. WEIRD that the pumpkin incident was NUMEROUS YEARS BACK FROM TODAY'S DATE OF July 2025 and very well could have been very close to brick incident. It could very well be unrelated and random but if case is unsolved?? I am coming forward anyway.  Ask Edmonton Police Service or Crime Stoppers???
