Authorities say a Greece man suffered third-degree burns over 30 percent of his body after a gas can in the trunk of his car ignited at a gas station early Wednesday morning. It happened near the intersection of Portland and Clifford Avenues shortly after midnight. The car fire happened right outside the front door of the gas station store. Rochester police say when the man placed a gas can in the trunk of his car something caused it to burst into flames, igniting the car and mans clothes on fire. Police heard loud explosions near this Rochester gas station shortly after midnight.
