Chapter 4: Back to School

"Good morning, Alexandra," one of her co-workers called out as she got out of her car.

"It's morning, the jury is still out on the good part though." Alexandra slung her bag over her shoulder and joined her co-worker as he walked. Joseph was one of the older employees in her division and like several of the other guys, had become quite over-protective. "Whoops, hold on, I left my cell phone." Lexa ran back to her car, grabbed the phone, stared at the object that had caught her attention, and then walked back to Joseph.

"What's up?" he asked, as they continued walking.

"Who's car is that?" Lexa asked.

"That blue truck? I don't know. I've never seen it before. Why?"

"It just looks familiar."

"Other than here?" When Lexa nodded, Joseph stopped at the door. "Lexa, is something going on?"

She waved her building access card in front of the reader and opened the door. "It's nothing. Probably just looks like another truck I've seen," Lexa said, trying to reassure herself, but as she slipped the access card into her purse she saw the envelope she had found her door the night before and an uneasy feeling crept into her.

Gibbs arrived early to the office and having seen Abby's hearse in the parking lot, went on down to her lab. "Hey Abbs, did you go home last night?"

Abby looked over her shoulder at Gibbs. "Well not my home, I went to, never mind. Verging on over-share." She motioned for him to join her. "I identified a couple of the buildings; some of them were different sections of the same one. Based on building IDs I made two lists, complete with advising offices to check with."

"That's good work Abby, really good." He took the papers she was offering and glanced over them. "Thank you."

"I just hope it helps. I'm trying to get access into the student database right now. I figure I can narrow the search by age and some physical characteristics. Then I'll just go through the results manually."

"Abby, slow down. Go have something for breakfast." Gibbs kissed her on the side of the head. "I've got to get back upstairs."

ooooooooooooooooooo

"Hey Boss, you ready to go?" Tony asked as Gibbs strode off the elevator. Ziva and McGee were also already present.

"Let's go." Gibbs grabbed his gun from his desk drawer and slipped it into his holster.

"That would be a yes." Tony felt a smack to the back of his head. "Boss, don't you think the gun is overkill, we're going to a college, not a prison. Although college can be like a prison." Another smack.

"You should always be prepared Tony," Ziva added.

The ride to the campus was short, seeing as how Gibbs was driving, and after finding a parking spot the four piled out of the car. Gibbs handed one of the sheets Abby had given him earlier to Tony. "You and Ziva get started on this one. McGee and I will work on the other. Call if you learn anything."

Tony and Ziva nodded. "On it boss. We'll catch up with you later." Tony held up the map provided and frowned.

"Upside down, Tony, you are holding upside down." Ziva yanked the map from his hands and turned it right side up. "Better."

"Advising office number four of the morning." Tony tucked the list and map into his pocket and held the door open for Ziva.

The receptionist looked up at them. "How can I help you two?"

Ziva held out a copy of one of the photos they had received. "Is the girl a student here?"

"I really can't say, I see so many students come through here. You might check with any of the advisors that are in today. They might remember her."

"All right, thank you." Tony led Ziva to the closest office. Four advisors later, things were looking a little more positive.

"Yes, I'm fairly certain she was one of my advisees. May I see the photo?" The advisor took the sheet of paper and held it closer. "Alexandra, very smart. She graduated last May. Was accepted into the graduate accounting program."

"Do you have a last name for her?" Tony asked.

"I can't think of it off the top of my head. Let me look it up."

Ziva looked at Tony nervously. They were both thinking the same thing. Is this her?

"Here we go, May graduates, Alexandra Mitchell."

"What else can you tell us about her?" Ziva took the photo back.

"Not much since she finished her undergrad. You should go upstairs and talk to them. They can tell you more. Third floor, office 306."

"You've been very helpful, Ms. Evans, thank-you." Tony moved towards the door.

"Is Alexandra all right?"

"Of course, we just need to make sure everything is ok," Ziva assured her.

Out in the hall, Tony stopped Ziva at the bottom of the stairs. Do you think we should go ahead and call Gibbs, tell him we might have found her?"

Ziva shook her head. "No, we should make sure it's her, gather as much information as possible."

Office 306 was easy enough to find but proved rather advisor-less. "The graduate advisor has left for the winter break and I'm new. Is there anything else I can do to help?" the receptionist asked.

"Is there anyone else here that might know her, be able to give us more information on her? All we have is this photo and a possible name." Tony sighed as things went downhill.

"Well, there's still professors around. Let me look up her past class schedules. What did you say her name was?"

"Alexandra Mitchell."

The receptionist turned her attention back to her keyboard. "Alexandra Mitchell, oh, here, we go." She pulled out a piece of paper and pen and wrote down some names. "Those were some of her teachers. One of them she's had twice, Dr. Harrell. I think he's still around – I saw him this morning. His office is 337."

Ziva and Tony thanked the receptionist and went to find Dr. Harrell. His office door was only open an inch so Tony knocked.

"Yes, please, come on in," A voice called from the other side.

"Dr. Harrell?" Tony asked.

"Yes, and you are?"
"Agent Dinozzo and Officer David, NCIS. We have a few questions for you."

"Of course, please have a seat." The professor, probably in his sixties motioned at the two chairs across from his desk.

"Dr. Harrell, do you recognize the woman in this photo?" Ziva handed him the copy.

He studied it and then looked up suddenly. "Heavens yes, this is one of my students. Alexandra Mitchell. She's actually going to TA a class for me next semester. Is she alright? I just talked to her the end of last week."

Tony glanced over at Ziva and allowed a small smile to creep on to his face. They had found the girl in the photo. Now the question became, was she Gibbs' daughter?
