A rock the size of a basketball killed a 75-year-old school bus driver on the weekend when it was dropped from a freeway overpass and smashed through his windshield.
Edmonton police Detective Ernie Schreiber says Robert Arthur Stanley managed to pull over and park the bus.
He was found by a passing police officer who tried to revive him but he was pronounced dead at hospital.
