The next morning started off early for the crime lab. Flack and Danny headed to the university to search for Emily McKenzie and Staci Collins. They each took separate directions. Flack headed into the student union building, which was already crowded with students.

" Looking for these girls is like looking for a needle in a haystack," Flack thought.

Flack looked around and thought he saw Emily McKenzie sitting at a far table. He walked closer and knew it was her.

" Emily McKenzie?"

Emily looked up at Flack.

" Yes. Who are you?"

" Detective Flack, NYPD."

Emily didn't know what to say.

" What can I do for you detective?"

" You know an Ethan Crowley?"

" Yes. What about him? I've been trying to forget about him."

" He's dead."

Emily got up.

" What did you just say?"

" Ethan was found dead in his car late last night."

Emily sat down and put her head in her hands, but then looked up at Flack.

" That's hard to believe. Who would want to do that to Ethan?"

" Why don't you tell me? Where were you at 11 p.m.?"

" Home. I live alone, so I don't have anyone who could back me up. I wouldn't kill him though."

Flack sat down in a chair across from her.

" How long were you and Ethan Crowley together?"

" About a month. It was a bad break up. He cheated on me. When I found out, I broke up with him. I can't believe he's dead."

Flack showed her a photo.

" Do you know her?"

" That's Staci Collins. We've some classes together. Speaking of which. I have to go."

" We're not done here yet. Do you know where I can find Staci Collins?"

" Yeah, where I'm going now. If you have any more questions, I'll answer them."

Flack nodded his head and followed Emily to the liberal arts building and into a room at the far end.

" That's strange. Staci is usually here by now, she sits right there."

" Do you know where else she would go?"

" Not really. She lives with her mother I believe, some apartment in lower Manhattan. Staci keeps to herself mostly. She was the one I caught Ethan with."

Flack wrote down what she said.

" Do you need anything else? Class is about to start."

" I guess we're done for now, but if you think of anything else, let me know."

Flack handed her a card, left the room and made his way out of the building. As he was heading out, he saw Danny.

" You have any luck?"

" I did find Emily McKenzie, but Staci Collins so far is out of our sight."

" I talked to some people about where they might be. What did Emily have to say?"

" Only that she dated Ethan and that she broke up with him when she caught him with Staci."

Danny nodded his head.

" So do we keep looking for Staci Collins?"

" Let's get back to the lab and update Mac, then we can go back out and look for Staci Collins."

Meanwhile, in another part of town, Mac and Stella went looking for Alex Crenshaw who wasn't at his apartment. Tenants in the apartment told them of Alex's hangouts and they went searching in those. Most of the places were dead ends, but they found him in a bar in midtown.

" Alex Crenshaw?" Mac said.

Alex looked at him.

" That's me. I remember you," Alex said to Stella," You find who killed Ethan yet?"

" We're working on it," Stella answered," In fact you need to come with us."

" Why? I didn't kill him. Ethan was my best friend."

" We can do this the easy way or the hard way Mr. Crowley," Mac said," I prefer the easy way."

" Fine, but I don't know what else to tell you."

Back at the lab, Danny and Flack went looking for Mac, who wasn't in his office or anywhere else in the lab. They saw Lindsey instead.

" Where's Mac?"

" He and Stella went to look for Alex Crenshaw. His blood was also found in Ethan's car on that rag we found. Did you have any luck?"

" We found Emily McKenzie, but Staci Collins so far is MIA," Flack answered," I'm going to check out her apartment."

Flack left the lab.

" There's not much else to go on. Someone hated Ethan Crowley enough to kill him," Danny said.

" It's our job to find out who Danny, and we will."

Danny's phone then rang. He was only on a few seconds before he hung up.

" That was Mac, he wants me to go pick up Joelle Richardson. Stella and Mac are taking Alex Crenshaw to the precinct."

" Do you think he knows more about what happned?"

" We'll soon find out and then we can solve this case."
