Adam happened to be at the diner eating, when he noticed Charlie was there and called Mac. When Mac and Jo arrived, Charlie was just finishing up his breakfast with his friend. They walked in, looked around, then noticed Charlie and his friend walking towards the front so they could pay for their food. They didn't notice two detectives walking towards them.

"Charlie Harmon?" Mac asked.

"Who's asking?" Charlie asked, not happy to see two people call his name.

Mac moved the side of his jacket to show his badge and said, "I'm Detective Taylor and this is Detective Danville. We have a material witness warrant."

"Man, you cops are the same. I want a lawyer so he can file harassment charges against you," Charlie angrily said.

"That's fine. Maybe we will file assault charges against you as well," Jo said sarcastically.

Charlie scoffed, "Y'all are trippin'."

After the lawyer spoke with Charlie at the precinct, they went in the interrogation room where Jo and Mac met them. Jo put the laptop and file on the table.

"So, my client gets pulled out of breakfast because you didn't go to his house last night," Roy Dibble said.

Jo stifled her laughter while she sat down and Mac remained standing near the table. "We know he was home but his dad told us he wasn't. His father is now looking at an obstruction charge."

Charlie sat forward and looked at his lawyer, asking, "Can they do that?"

Roy looked at him. "If you were home and your father said you weren't, yes." He looked at the detectives and said, "You say my client committed assault. I don't see a report by Darlene Viola."

Mac and Jo looked at each other then she took out some pictures that showed the assault. "Here is the evidence."

"These can be photo-shopped. But since there is no complaint filed, then there is no charge," Roy said.

Mac then sat next to Jo, turned on the laptop, turned it towards them, and played part of the tape. Mac told them as Charlie looked nervous, "We also have witnesses."

"How about a search warrant?" Roy asked. Jo put it on the table right in front of him. "I still don't see a complaint filed against Charles." Roy crossed his arms and smirked.

Mac and Jo looked at them quietly.

"You gotta be kidding me," Charles said annoyed.

"That's what I thought," Roy said as he started to get up.

Mac walked over and stood behind Charlie before firmly saying, "Sit your ass down!"

"What is this?" Charlie asked annoyed as he was angry at Mac for pushing him back to his seat.

Roy then sat back down as well. "It was in the heat of the moment, I'm sure my client will apologize to Darlene."

Jo started to laugh. "I'm sorry, I have to get some air." She got up and went in the viewing room since she started to get upset while Roy looked at Mac confused.

"I think your woman needs to man up and be a woman," Charlie said rudely.

Mac stared at Charlie, narrowing his eyes at him. "No. It's just that you hit a girl, a few days later she is dead. We find out about you hitting her so we come to your home and your father says you are not home when you are. You better have a good alibi pal, because you are my number one suspect."

"Wait a minute, I didn't do this!" Charlie yelled.

Roy said, "Let me talk to Charlie alone." Mac stood up, took the files as well as the laptop, and went in the interrogation room.

He looked at Jo and asked, "Are you okay?"

"Yeah."

"What do you think?"

"I don't think he did it. And plus the way he reacted when you told him she died just doesn't seem like someone who did it."

Mac saw Roy approach the glass. "We'll find out." Roy knocked then sat back down while Mac went back in the room and sat down.

Charlie asked somberly, "Is she really dead?"

"Yes, she is," Mac said.

"How?" Charlie asked.

"She was shot," Mac said somberly as he looked at him. "So, where were you on March 17th from noon until three?"

"I was at a club where some of my friends were practicing their performance in the band."

Mac gave him a pad and pen and said, "Okay. I need their information." Charles wrote down the names of people who were there that day.

At the impound yard-

Adam and Lindsay looked over Darlene's car that was found two hours earlier in a parking garage.

"I think our killer was starting her period," Adam said as he swabbed the blood on the car seat.

"Why do you say that?" Lindsay asked, a little annoyed.

"Because there is quite a bit of blood on the seat where we sit."

Lindsay thought for a moment. "I did find a tampon in the bathroom at Darlene's home and it didn't belong to her or her mother." She continued to look in the trunk where she saw a white sheet. "I bet the killer wrapped her in this sheet after killing her but I can't see anyone not notice a woman carrying a body over their shoulder."

"Is there any blood on the sheet?"

"No," Lindsay said while she put the sheet in the evidence bag.

Adam finished processing for fingerprints then went in the back seat and saw something he thought was very interesting. "Lindsay, I think she was shot here."

"What makes you say that?"

"I see gunshot residue on the seats, and blood on the window, as well as more GSR."

"That must have been loud." Lindsay walked over to the door of the back seat.

"Maybe she changed her in here, waited a few hours for the blood to dry." Adam got out and stood near Lindsay.

Lindsay shook her head. "I'm not so sure Adam."

At the lab-

The lab had gotten video of Darlene buying her lunch at a fast food drive thru. Sheldon was seated, scanning over the video, and saw a woman in the passenger seat. Mac walked up to him as he turned his head towards him then turned back to the screen.

"Anything?"

"This woman may have been the last person to see her alive but the angles of the cameras just make it difficult to get a good photo ID." Sheldon pointed to the box and said, "I have more to look through."

"Okay. I'm going home for the night. See you tomorrow. Night."

"Night, Mac."

Mac walked away while Sheldon finished looking over the video, then he completed the daily log before heading home for the night.

At a party later that night-

Adam met Annie and Max at a friend's birthday party. He was dressed casually while she wore a dress and Max wore a blue onesie but slept most of the time.

"Glad you guys could make it," Angela Morgan said.

Annie smiled as she put her arm around Adam's neck. "Thank you for inviting us and letting Max sleep in your room."

"No problem," Angela said with a smile then went to talk to some more friends.

"How is work going?" Adam asked her.

"Good. Just glad to be doing something else but I really wish you can just leave the lab when you can," Annie said.

"I cannot keep doing that," Adam told her.

Annie folded her arms and looked at him annoyed. "Does anyone in the lab know about Max?"

"Yes," Adam said.

"How many and who?" Annie asked.

"Two. One of them knows because I had left a crime scene because you needed me. I should be lucky she isn't my boss," Adam said nervously.

"I guess you guys don't talk about your home lives, huh?" Annie was upset.

"No. And if one of my co-workers suddenly has a girlfriend or is having problems, he won't tell us," Adam said.

"Oh. I guess I can see that, I mean, I don't tell my co-workers much about you or Max," Annie said.

"I'm sorry that it upset you," Adam said.

"I'm going to go talk to some other friends, okay?" Annie said while she put her arms down and walked away.

A few minutes later he walked towards the kitchen when Tim Guillen, a friend of Annie's, stopped him.

"Hi. You must be Adam Ross."

Adam was taken aback since he didn't know Tim then responded, "Yeah. How did you know?"

"I'm Tim Guillen and I went out with her a few times. When you guys had your pictures taken, she showed me the photo and we loved it."

"Oh, nice. Wait, you went out with her? When?" Adam asked shocked.

"A few months ago and we broke up a month after that. It's too bad Max's real father doesn't even know he exists."

Adam looked at Tim surprised as his eyes got bigger and he exclaimed, "What?"
