the thing is DNA / fingerprinting etc takes up police resources. At this point the bike has probably exchanged several hands. My feeling from them is that they're not that interested/have way too much other stuff to do ...
okay, everyone still on the hunt for this little guy ... keep eyes peeled.
Or on either of the bikes, especially under top tube etc. Same prints on both bikes and you have the perp?
Oh, and upgraded with lights = win. Maybe 😒
