Again I plunge into the oddest corners of crossover fiction. This is un-beta'ed so I apologize before hand for any mistakes. I hope you enjoy and get a laugh out of it. This is just the beginning.

Chapter 1

Gibbs got the call as he was walking into the Bull Pen. He could hear DiNozzo talking about some obscure movie and figured he was picking on McGee again. Gibbs shook his head as he walked up behind his agent and smacked his head. He laughed to himself as DiNozzo apologized. He'd never admit it, but sometimes he didn't know why Tony needed a Gibbs' head smack but the guy looked so guilty that Gibbs figured it was deserved.

"Grab your gear," the former marine barked out, grabbing his jacket and gun. "Got a dead marine in New York."

"New York, Boss?" McGee asked. "That's a long drive."

"I know, McGee, but I got the call," Gibbs said as he waited for the elevator doors. He slipped in as soon as they opened and waited impatiently for his team.

DiNozzo was the last one in. "I hope this one is quick," he said as the doors closed. "I have plans this weekend."

The team arrived at the scene just as it was getting dark. The local PD had lamps set up so they could see the crime scene. There seemed to be more uniforms than usual, and they were all nervous.

Ducky was already kneeling by the body. He only beat them because DiNozzo, whose turn it was to drive, got them stuck in traffic. Ziva was still complaining as she started taking pictures of the crime scene.

"What have we got, Duck?" Gibbs asked as he looked over the scene. Something didn't feel right, another gut feeling, but he couldn't put his finger on it. The hairs on the back of his neck prickled, like he was being watched. He shrugged off the feeling for now, but he stepped up his vigilance.

"Well this poor man was certainly in quite a brawl, Jethro," Ducky began as he slid in the liver probe. "Look at the defensive wounds on his hands and bruising to his face. But cause of death appears to be these stab wounds," he pointed out the bloody slits in the marine's chest and abdomen. Checking the probe he continued, "He died sometime last night; look at the stages of rigor mortis. You know this reminds me of a time back in my student days…"

"Duck," Gibbs interrupted, because if he didn't they'd be here all night. "Anything else?"

"These bruises look like they came from a blunt object, and were administered shortly before his demise. Of course, I'll know more when I get him back to Autopsy."

"He was tortured?" Gibbs asked.

"I'm not sure, Jethro. You'll just have to wait," Dr. Mallard scolded gently.

"Okay, Ducky," Gibbs said has he held up his hands to placate the older man. He turned his focus to his team, "McGee!"

McGee was improving; he only started a little before he started his report. "Corporal James Barry, three years of service, one tour in Afghanistan. He was on leave to visit his family here in New York." It amazed Gibbs the stuff the kid could pull off his phone.

DiNozzo ran up to give his report. "Talked to the local LEOs. They said that they found the body this afternoon and after finding the military ID, called us. They canvased the area but no one's talking, and everyone is really jumpy, Boss. I don't like it."
"Why are they jumpy, DiNozzo?" Gibbs said with a frown. His neck was still itching.

"The gangs are really bad in this area, Boss. There seems to be some kind of gang war going on but all they ever see is the aftermath. They don't even know all the players. It's so bad that if our guy wasn't a marine, they would have just written it off as gang violence or a mugging and moved on. They're stretched real thin, Boss."

Gibbs considered their choices. There weren't many. "Okay, let's wrap up the crime scene and get a hotel for the night. We'll canvas the area in the morning. Maybe someone will talk to us, if they won't talk to the police."

"Gibbs," Ziva called.

Gibbs left DiNozzo and McGee to finish their jobs while he went to where Ziva was pointing out a blood trail.

"Blood," the former Mossad agent stated redundantly.

"I see that, where does it lead?"

Ziva just shrugged and started to follow it as she continued to snap pictures. The trail led out of the alley and down the street. It ended in a bloody cloth thrown on top of a locked dumpster. At least they didn't have to dig to find it. Ziva bagged it while he looked around. This alley looked the same as the last one except for some interesting graffiti. Why would anyone spray paint impaled turtles?

Suddenly they heard a crash at the far end of the alley. Gibbs and Ziva shared a look and both pulled their weapons. They advanced on the source of the noise which sounded like an on-going fight. They rounded the last dumpster to see a man in a hockey mask swinging a baseball bat at a group of punks. It was four against one and the punks had metal pipes and chains. Even so, Hockey mask was holding his own and had one of them on the ground. Gibbs shared another look with Ziva. She smiled, the one that usually made DiNozzo shiver, and nodded.

"Federal agents, freeze!" the NCIS agents shouted as they came out, weapons at the ready.

The punks shouted and turned tail, running into the dark and dragging off their injured friend before the agents could make a move. Hockey mask froze for a second, which was long enough for Ziva to get the drop on him. The man shouted something weird, googoo-something, and swung the bat but Ziva dodged and grabbed the bat before he could get his stance back from the missed swing. Another few seconds, and he was on his back with Ziva on top, pinning his arm behind them.

Gibbs picked up the bat and eyed the golf-bag full of other sports equipment near-by.

Ziva looked up and followed his gaze. "Ducky said that our victim was beaten by a blunt object."

Gibbs nodded. Looks like the plan needed to change.
