DC homicide Detective Anthony DiNozzo sat at his desk, filling out some paperwork when his partner walked in the room. "Looks like we got anothe case, Tony." Detective Dan Williams announced.

"What is it?" Tony asked his partner as he grabbed his jacket and stood up.

"A John Doe, found in the park." Dan answered, as the two men walked out to their car.

Tony hopped in the driver's seat and Dan in the passenger's. Tony turned the key and soon they were off. After a few moments, they arrived at their crime scene. The ME had already arrived adn was performing his preliminary emanination. Tony walked over to him "TOD doc?" Tony asked.

"Based on liver temp, about eight hours ago." He answered.

Tony nodded. "Looks like defensive wounds on his hands." Tony observed, sipping his cup of coffee.

"We'll get him back to autopsy and find out more." The ME replied. The body was loaded up and Tony and his partner got to work. Tony spoke with the young couple that found the body while Dan worked on collecting evidence. After Tony took their statements, he walked over to Dan.

"What have you found?" Tony asked.

"Well, we have some broken glass fragments here, some foot prints there, and a used condom over that way." Dan answered.

"Probably from some teenagers." Tony said, referring to the condom.

"Or our murder could have been a black widow." Dan countered. "Seduces him and then kills him afterwards. Could be our John Doe's DNA."

"Good point." Tony replied. "I still think it's some teenager's."

"That a bet?" Dan asked.

"You wanna make it one?" Tony asked.

"Don't I always?"

"True." Tony answered. "You're on."

A few hours later, Tony was back at his desk, looking over the pictures from the crime scene. "I got the report on our used condom." Dan said, walking in and holding a folder.

"What is it?" Tony asked.

"The DNA inside the condom matches out John Doe." Dan answered. "Jack is running John Doe's finger prints and DNA through every database trying to find out who he is."

"Was there anything about DNA on the outside of the condom?" Tony asked.

"It's definitely female." Dan answered. "Jack ran it through the usual databases and found nothing, so our unknown female has no criminal record. Of course, Jack is running it through every DNA database as well. Now pay up, DiNozzo."

"The usual?" Tony inquired.

"Yup." Dan replied.

Tony rose from his desk. "Alright, let's go to the donut shop." Tony said.

Tony and Dan arrived at the donut shop. Tony and Dan ordered their favorites and Tony coughed up the cash. The two sat down at a table and dug into their favorite snacks. "So, whatever happened between you and that waitress from the bar the other night?" Dan asked Tony.

"We went out on one date." Tony answered. "And that was it."

"She slapped you when you moved in for the good-night kiss, didn't she?" Dan asked.

"Yes." Tony answered, hanging his head. "Then she told me she never wanted to see me again. I have no idea why."

"Let me guess, you took her to a nice place and your waitress was pretty. When your date went to the bathroom, you flirted with her."

"Were you following me last night?"

Dan chuckled. "No, I just know you. She probably saw you flirting with the waitress, but she had a level enough head not to make a scene."

"That would explain a lot." Tony replied.

"It was probably for the best." Dan said. "Ever since you and Wendy broke up, it's been an unending stream of waitresses and bartenders. None of them challenge you. That;s what you need, a woman that challenges you."

"What are you a shrink now?" Tony asked.

"No, I'm just saying. You're my partner and my friend. I want you to be happy." Dan replied.

Just then Tony's cell phone rang. He flipped it open and looked at the screen. It was Jack from the county lab. "What is it Jack?" Tony asked.

"I got a hit on our John Doe's DNA." Jack answered.

"Well, who is he?" Tony asked.

"See, that I still don't know." Jack answered. "The hit was from a rape case. The guy was a rapist."

"Who was the victim in that case?" Tony asked.

"A Navy Petty Officer, Jan Wilks." Jack answered. "That's why I'm calling, soon after I made this discovery, a bunch of guys from NCIS came in and took the evidence, saying that they were taking over the case."

"Alright, I'll straighten this out." Tony said, hanging up the phone. He looked at his partner. "Our John Doe was a rapist. His DNA matched a rape case, investigated by NCIS."

"Why do I feel like there's something else going on?" Dan asked.

"People from NCIS came and took our evidence, thinking that they can take over our case." Tony answered.

"We can't let that happen. They'll never keep us in the loop." Dan replied.

"Yup, so we're going to NCIS."
