You had a troubled past. Your parents were murdered so you were to live with your uncle, who... Was also a sick murderer. You were afraid of being moved to somewhere similar— thanks to your bad luck, so you ran from the police and hid. When they didn't find you they assumed you were dead, so they left your case alone.
Tim was assigned on all of those cases, so he got to remember your face quite well. He was there when you tried to run and cry for your parents, forcibly holding your sobbing self when you took in the death of your parents. He was also there when they found out your uncle was murder, again, it was Tim dealing with you.
Moving two years forward, fate decided that you need more police trouble.
"E-Excuse me? I need a..." You stumbled out, trying to catch attention of one of many officers—, who seemed in no rush to pay attention to you.
"I have a.." Yet another officer passes by you. You were about to give up, maybe coming here wasn't a good idea. You were about to turn around when you heard a voice behind you.
"Who's damn kid got lost?"
You immediately turned around, seeing an officer— sergeant—, that was just too familiar. And he seemed to recognize you too. Disbelief and shock was written in his face. Understandably so, since the end of your case ended up with a conclusion of you being dead.
