You need to try to do something with the two pieces of glass with the partial prints. There is also evidence at the thug hangout that is important [which will also need to connect with the partial prints]. Also be sure to get the evidence in the restaurant alley way and outside the pawn shop by the trash can.
You have all the evidence from the asylum I believe- focus on doing something with the glass pieces and evidence from other locations
