At the station, Detective Lily Rush is sitting at her desk, finishing up some paper work, Detective Will Jefferies relaxes in his chair at his desk, with a chocolate covered sprinkled doughnut in one hand and a coffee in the other, and Kat comes in late with her coffee and drops her bag on her desk and starts searching her bag. At that moment, Nick and Scotty walk in with a box that hasn't been solved. Lily is the first to notice, with curiosity.

"What's up guys?" Lily places her pen down as Vera drops the box on her desk.

"We got another cold one." Nick explains.

Lily opens the box. "How cold?"

"2001." Nick responds.

"Huh, more like kinda chilly then cold." Kat jokes as she continues to search her bag not looking at the others.

Nick grabs a file from the box, opens it and begins to read it off. "Catherine Walkins, born on Aug. 27, 1985, died May 2, 2001."

Kat stops searching her bag, looks up at Nick and walks away unnoticed.

Lily's interest in the case strikes. "This girl was only fifteen. Cause of death?"

Nick continues reading off the paper. "Fractured skull from a nearby brick. Found in the parking lot behind her school, P.L.J.D. Academy."

Scotty has a moment of thought. "I know that place. They use to sentence juvenile delinquents there sometimes if the judge gave them the option to go there instead of the juvenile detention center. Help them get on the right track. It's an alternative school now." He hands Lily the notebook diary. "Possible diary of the victim."

Lily read the cover. "Luke Skywalker?"

Nick grins. "Exactly what I said." He continues reading. "She was sentenced to the academy for assault in 2000, her cousin was already sentenced there two years before."

"Maybe her cousin may be able to remember something." Lily opens up the notebook and sees two pictures of the victim. The first one was a school photo, perfect innocence with the perfect smile, with her long blonde hair, and the second photo was of the same girl with shoulder length black hair and dark clothing, no smile. "Well, we can definitely say that this girl's image transformed over her time at the academy." Will walks over behind Lily as she looks over the new possible evidence while eating a doughnut. "Any suspects?"

Nick scams the file. "Yeah, a Kimberly Miller."

Will looks up at Nick with question. "Did you say Miller?"

Nick smiles. "Hey Miller, is she a relative of yours?" he asks in a joking manner. He turns around, only to realize that Kat already left her desk. "Where'd she go?"

Everyone scan the room until their eyes land on Stillman's office, seeing that Kat is in his office talking to the boss, unsure on what the conversation is about or how it was going.

In Sillman's office, Stillman is sitting on the front of his desk while listening to Kat, not full aware of how worried his detective his.

"I don't want to be on this case at all, boss. I really want to sit this one out."

Stillman slightly nods his head. "We are here to do a job. You can't just go and 'sit one out' whenever you feel like it. I understand why your reasons for not wanting to do this, but you may be the one who can find the killer of this poor girl. You're the one most familiar with this case."

"My sister was the lead suspect, of course I know this-"

"I want you and Vera on this, Miller. Follow up on the lead Have Scotty and Lil' pay Catherine's cousin a visit." Stillman orders.

Kat sighs of worry. "Yes sir. I'm on it."
