Patience, patience....believe me, the DA's office is scrambling, and rather than miss an indictment, they are getting ready for the next session. They will want more than one charge so that at least ONE sticks to that scum. Remember, take away ONE person's constitutional rights, you take away ALL of our rights. So try to hold the anger in check, know Michael would not want you SICK over all this. Talk to you your paster, priest, minister, get into some counseling, call MADD, get in touch with others who totally understand your anger, grief and frustration, and talk, talk, talk about it until you are exhausted and can take a deep breath.
This animal has some powerful karma working against him now, and life has a way of taking care of them...rest assured his future holds horror, and you won't have to do a thing except enjoy it when it happens as your right for revenge without actively participating! The police will watch him like hawks for another slip-up and excuse to arrest him, trust me.
In the meantime, take care of yourself and the things you know Michael loved....for his sake!
Hugs, pelli
