Emily looked around the room she was in and couldn't put her arms around why she was brought there. There were things to clear up with the detectives and maybe this was the best place for her right now. Emily saw the door open and Flack walked in.

" Ms. McKenzie. We need to clear up some things."

" You may call me Emily detective."

Flack sat down across from her.

" You came to see Staci and noticed the scene around you."

" Yes. Then I saw Staci being brought down in handcuffs. Staci didn't kill Ethan."

" How do you know that?"

" Staci was with me that night."

Flack sat back and looked at her.

" Why didn't you mention that before? You told me that Staci always showed up to class early."

" She usually does, but that night we decided to study together. Staci wanted to leave, but I wouldn't let her because she got drunk. She spent the night at my place woke up that morning with a bad headache. Staci went home a few hours later."

Flack wasn't sure what to believe, he felt that Emily was hiding something else.

" You need anything else detective? If not, I have places to be."

" Right now, you're going to stay where you are."

Flack got up.

" You can't keep me here."

" Sit tight. I'll be right back."

In another room, Staci stared at the ceiling. Mac sat down across from her.

" This would be easier if you cooperated Ms. Collins."

Staci looked at him.

" Are you a cop or a scientist? You did say you worked with the crime lab?"

" I'm not in the mood for an attitude problem here."

" Too bad. I've said all I've could. I didn't kill Ethan."

" How did you know we were looking for you?"

Staci shook her head.

" Somebody warned you that we were coming."

" So what if they did. I have a right to feel safe, even if it's from you."

" Who warned you?"

" Emily did. When she told me that Ethan was dead, I didn't know what to think. All I knew was that I didn't kill him. I was with Emily that night. We were studying."

Mac got up.

" May I go now? I have more studying to do."

" I'm not through with you yet."

" What else do you need to know? I don't know what else to say. Ethan broke my heart when he dumped me. Then he started dating Clarissa. Clarissa did all she could to steal him and do you want to know why he was still with her, it's because she would sleep with him. I wouldn't so Ethan went with someone he knew would. You want to know more talk to Clarissa."

" Sounds like you two don't get along."

" We're in the same program, but that doesn't mean I have to like her."

Mac went out of the room and caught up with Flack.

" What did Emily tell you?" Mac asked.

" I don't know if it's the truth or not, but Emily told me that Staci was with her the night Ethan Crowley was murdered."

" That's what Staci just told me. Emily warned Staci that we were looking for her."

" Which explains why she went up to the roof."

"She didn't want to talk to us."

At that moment, a woman came in and looked around. Mac went up to her.

" May I help you?"

" I'm looking for whoever is in charge here. I want to see my daughter. She called me and told me to come here."

" Is your daughter named Staci?" Flack asked.

" Yes. I'm her mother. I'm Katherine. Where is Staci?"

Mac led Katherine to where Staci was.

" Why is she here? I don't understand it."

" Do you know a man by the name of Ethan Crowley, Mrs. Collins?" Mac asked.

" Yes. He's Staci's ex-boyfriend, but that doesn't tell me why she's here and who are you?"

" Detective Mac Taylor, I'm with the New York Crime Lab. Staci is here for questioning in the death of Ethan Crowley."

Katherine frowned.

" You've been questioning my daughter. Wait, Ethan's dead?"

" He was found the other night in his car," Flack answered her," Staci is a suspect."

" My daughter isn't a killer. You have no right to keep her here. I'm taking her home."

" Staci isn't going anywhere," Mac told her," I do have a right to keep her here for 48 hours. Did you know she was up on the roof of the apartment building with a gun?"

Katherine looked around, but then sat down.

" I still can't believe I kept that thing. It belonged to her father. Staci's been having a hard time since then. Her father was killed in a car accident almost a year ago. I guess you'll discover that the gun is still in her father's name. Look, I'll bring Staci back here. Let me take her home."

Mac just walked away and into the room where Staci was.

" Your mother is here."

Staci didn't look at him.

" At first it seemed like you wanted to fight me, but then you gave up."

" Why fight what you can't," Staci said not looking at him," You're the one who told me not to make it worse, so I didn't."

Staci then looked at him.

" So may I go home now?"

" We may need to ask you more questions."

" I didn't do it. Ethan may have been a complete jerk to me, but I didn't kill him."

Mac opened the door. Staci then saw her mother standing there.

" Mom."

" Staci, are you okay."

" I'm fine, but Ethan is dead."

" I know, the detectives told me."

Mac looked at Staci and then her mother.

" You can go home, but I may have more questions later."

Staci only nodded her head and went out of the precinct with her mother. Flack then went into the other room where Emily was.

" What's going on?" Emily asked.

" You can go now, but don't leave town."

" Why would I? I have nothing to hide and Staci didn't kill Ethan, but I think I may know who would. You need to go talk to Alex Crenshaw."

" Why's that?"

" Ask him that. He knows what Ethan was like and hell so did Joelle. They did nothing about what Ethan was like. Ethan Crowley was a heartbreaker. To me, he didn't even have a heart."

Emily then also left the precinct. Mac came up to Flack.

" I don't know what to believe Mac. We have a list of suspects, but they've all been cleared. All of them have solid alibis."

" There's more to this Don and I'm going to find out what it is."
