Tim tried to sneak into Ballistics unnoticed but Calleigh turned around and smiled at him.

"How do you do that?" he wondered.

"Sixth sense. I don't think we're looking at only Webster." Calleigh said. "Come and take a look at this."

Tim stepped behind her and peered into the microscope.

"The bullet on the left is the one that Alexx pulled out of Matt. The bullet on the right is the one she pulled out of David." Calleigh explained.

"They match up perfectly."

"Its a .22 caliber. Now look at this." Calleigh quickly switched one of the bullets. "This is the bullet from Stacie and they don't match up at all. This is a 9mm."

Tim pulled away from the microscope slightly and stared at Calleigh.

"I need to find that gun." she said. "And there is no one left in the Collins household to tell me if Matt owned a gun."

"Did you check the house for a gun?"

"When have I not looked for a gun?"

"True."

"I checked top to bottom and there was no gun anywhere. Now it could be David's gun but why would he have a gun on him in the first place?"

"Protection? I mean... if I walked into our house and found you bed with another guy I'd probably shoot him." Tim said. "He was paranoid and brought it with him."

"Well there's only one way to find out."

S/C------

"What do you want now?" David asked irritably. Tim tossed a file in front of him.

"That's the bullet we pulled out of you and the other one is the one we pulled out of Matt Collins's body. Tell us what happened." he replied. "And I want the truth. How did you two both get the same type of bullet in you if he just walked out of the house?"

"It was Jack."

"That's a lie." Calleigh said. "Stacie had a different type of bullet in her. David, you need to tell us what happened."

"Matt walked into the bedroom and started yelling. Stacie tried to calm him down, saying it wasn't what it looked like." Tim rolled his eyes at this. "He went crazy and walked out of the room. He came back in, a gun in his hand. I tried to get it away from him but he shot my arm. We wrestled for the gun for a few minutes and I finally got it away from him."

"How'd he get a bullet in his brain then?"

"I accidentally pulled the trigger."

Tim and Calleigh looked at each other.

"Look, I was afraid for Stacie. If I left he would've killed her." David said. "I didn't want her alone with him so yeah I shot him. Stacie started yelling at me that I was stupid and now I going to go to jail. I tried to get her to relax but she told me to get out. I wouldn't leave. I knew she was going to call you guys."

"So you waited around?" Tim asked.

"No." David shook his head. "I did finally leave but I got as far as the front porch when Jack came around the corner. He told me to stay and I'd see something I liked. I didn't want him to kill Stacie. I love her, okay but he would've shot me!"

"If you love her why didn't you take the bullet for her?" Calleigh asked.

"I'm not Prince Charming Barbie. Besides if I died he'd have just shot her afterwards." David snapped. "I wanted to get her to the ER but by the time Jack let me by her she was dead."

"Where is he?" Tim asked.

"I don't know."

"Don't give me that shit. Where is he?"

"He said something about going to see an old friend of his... name was... something with an S. I wasn't really listening."

"Was this a last name or a first name?"

"I wasn't listening!" David exclaimed.

"Where's he staying?"

"I told you the motel!"

"He's not there we checked. So you better tell us."

"He has a house in Coconut Grove. 1153 Grove Way." David muttered. Tim pulled Calleigh out of the room and let Tripp in to arrest David.

"Ooh I didn't ask him about the gun!" Calleigh exclaimed, running back in. "Where's the gun?"

"What gun?"

"The .22 you shot Matt with."

"I threw it out."

"Where?"

"The dumpster in my apartment complex. They already emptied it though. But I shot him. I admit it. Can't get nothing by you CSIs."

Calleigh scowled and went back to Tim.

"Well let's go get him." she said.

"What?" Tim asked.

"Well I'm not letting you go alone." Calleigh said.

"Well I'm not letting you go near that house. I'll take Delko."

"Tim..."

"He just killed another person Calleigh!" he exclaimed. "You heard him! An old friend something with an S? He escaped because he didn't finish us off. Or did you forget how to spell our name?"

"Oh well that's very kind of you. Leave me behind and if you get shot then I'm stuck by myself!" she yelled.

"I'm not fighting with you on this." Tim said, shaking his head. "Get back to the lab and I'll be back later."

"Calleigh!"

"What?" she barked. Hagen stepped back as Tim got on his cell phone. "What Hagen?"

"There was a fight over at The Whiskey Stop. It got out of hand."

"Whi..." Calleigh didn't finish her sentence. "Wait, why are you telling me this?"

"Yelina was over there and she said its not good. Your father was there."

"Oh my God..."

Tim snapped his phone shut and looked at Hagen.

"What?"

"He's fine." Hagen assured. "He's a bystander by he refuses to leave unless you come and get him. There's also reason to believe he may have started it."

Tim looked at Calleigh, who looked upset. These were the times Tim really hated his father-in-law.

"Horatio doesn't know but Yelina thought it'd be best if you worked the case. Can you get over there?" Hagen asked. Calleigh nodded and she and Tim walked towards the parking lot.

"Look... just go." she said. "I'm sorry that I yelled."

"Don't worry about it." Tim muttered. "Do you want me to go with you?"

"No. I'll be fine. Tim, be careful." Calleigh said quietly. He nodded and kissed her quickly. "I love you."

"I love you too. If you need anything with your dad just call. I'll let Delko handle this."

"Say my name?" he smirked, walking over. "Whoa... you okay Cal?"

"Yeah I'm fine. I'll see you guys later."
