"So Abbey tell me you have good news." Gibbs walked in a placed a Big Gulp on her desk. He had a Starbucks cup in his hand.

"The DNA on the note is not Captain Krennick's."

"Which leaves us with every other woman in the country." Gibbs sighed.

"You didn't let me finish Gibbs."

"Sorry Abbey."

"Let me ask you a question first what do you know how paternity tests are carried out?"

"They take a sample of the father and the child's DNA and run a comparison. Since the father's DNA accounts for fifty percent of the make up, there will be similar markers in the child's. But why isn't this relevant?"

"They don't usual check the mother's DNA because giving birth to the child is a good indication that they are the mother."

"What has this got to with the blood sample?"

"Fifty percent of the markers match, to a 99.99999999999999999999999% accuracy."

"You're saying she's Krennick's mother?" Gibbs questioned.

"No. Krennick's parents died in a car crash two weeks after she graduated the Naval Academy. I'm saying the blood belongs to her daughter."

"Daughter? Krennick doesn't have any children. I've been over her service file with a fine tooth comb."

"That's what I found too. So I did a little research and it turns out she does. She was born when Krennick was 16 and put up for adoption immediately. She didn't want anyone to know about it so didn't mention it to anyone when she joined the Navy. Turns out they had a little mother-daughter reunion about two years ago."

"Do we have any information on her whereabouts?"

"That's the real kicker. She joined the Navy too. Petty Officer 3rd Class Rebecca Shaw."

"Let me guess you've pulled her serve record."

"That's me always one step ahead. She's just been reassigned to, let's have a fan fare please, JAG Headquarters, Falls Church, Virginia."

"I'm heading back to JAG."

"She's not there." Abbey called when he was halfway out the door.

"And where is she?" Gibbs asked.

"She was given a week to get settled since she just came from sea duty. But I have an address for her apartment." Abbey held a piece of paper in her hand.

"Why didn't you say so earlier?"

"You didn't ask and I enjoy our quality time together."

"Now you're beginning to sound like my ex-wife."

"Which one?"

"All of them." Gibbs said walking out.

"Petty Officer, I need to see Admiral Chegwidden." Gibbs said striding in his outer office.

"I'll let him know you're here." Tiner went and knocked on the Admiral's door and went in. "You can go in."

"Thank you."

"Special Agent Gibbs. Tiner close the door on your way out." AJ said. "I take it you have an update."

"Do you know a Petty Officer 3rd Class Rebecca Shaw?" Gibbs asked.

"The name doesn't sound familiar should I?" AJ questioned.

"According to her service record she has been transferred under your command."

"Tiner." AJ yelled.

"Sir." He entered.

"Petty Officer 3rd Class Rebecca Shaw?" AJ said.

"She starts on Monday sir." Tiner replied.

"Admiral, in the interests of aiding the investigation while I talk to Captain Krennick as soon as she gets out of court, could you order her in. Tell her you need her to report for duty earlier than planned, and then have her taken into custody. We have people waiting at her apartment."

"Tiner, get on the phone. It's an order."

"Aye aye sir."

"What does Shaw have to do with this?" AJ asked when Tiner had closed the door.

"It was her blood we found on the second note."

"The approval for accessing the DNA database hasn't come in yet."

"But we did get approval for a DNA sample from Krennick. Shaw is her daughter."

"She never mentioned having a daughter when I knew her."

"She was put up for adoption; they met up again about two years ago by chance when they were stationed together."

"So this should be over quickly?" AJ questioned.

"It will still be a few more days."

"Very well."
