I think there should be so many (traffic) camera's LE should be able to see if a car showed up on them damaged (having hit a person) and not having damage on the previous camera. Or if there was odd behaviour by a car. I mean like missing time between camera A and B at a spot where there is no reason to stop etc. Also at the presser, they did not mention any such scenario nor did they ask the public if they noticed anything suspicious that night, like broken glass, blood on a road etc. Someone having a damaged car after that night without having an explanation for it. Nothing.
