Last year sons mini motorcycle was stolen from our front yard.

i called the police , some cop finally showed up that night. took a report. and end of story. A few weeks ago a guy sees my husband in the corner store and tells him, he bought this mini pcoket bike and he thinks it could be my sons.( its a very small town) anyways we go look at it and yeah there are some parts missing but it is my sons mini bike.This guy had already gone to the PD cuz he knew that my son had one just like it and that it had been stolen..cops tell him not to worry , he isnt in trouble and that I needed to show proof. OK so I found the paperwork that came with the mini bike.gave it to police yesterday and nothing! They havent even gone to this guys house to verify #'s/ What can I do to get some action outta these cops?
