Good job on getting the report done. If this ever happens to anybody else, and the police give you 'the run around', you can go to a CHP office and they will take the report at the desk.
When I get to work tomorrow I will see what I can find out for you as far as suspect info. To be honest, we really dont do much investigation in these cases... Pretty much, unless a cop gets behind him and runs the plate, it doesnt get found. Although, as a word of encouragement, your case is a little different because you have some suspect info.
Good luck.
