"Hey Marty." Lindsay said when walked into the morgue.

"Detective Monroe, you're looking good today." Dr Marty Pino commented.

"Thanks." Lindsay smiled. "What about our dead guy?"

"Tell me about the baseball flying at Danny and I'll tell you about the dead guy."

"Derek Jeter hit a ball and it went flying at Danny, he caught the ball which is now in my desk drawer. So dead guy?"

"Still no ID on him preliminary cause of death is a heart attack but I need to cut him open to confirm, I'm also waiting on a tox screen."

"So his wallet and ID just disappear or a well timed robber took them?" Lindsay guessed.

"Or a guy points a gun at him, he hands his wallet over and one dead guy from shock."

"That would work too." Lindsay replied.

"On your own for this one?" Marty asked.

"Yes. Anything else I need to know?"

"I found this in his underwear." He handed her an evidence bag.

"In his underwear." She looked at the piece of paper.

"Women keep things in their bras." Marty pointed out.

"Ten bucks for a cab or a phone number." Lindsay stated. "This is too long to be a phone number and are your underpants a good place not to loose something from? Why not a pocket, he had one in his pants and his jacket."

"That's a question for you to answer." Marty stated. "Clothes, shoes, fingernail scrapings, I haven't found any other trace. I'll let you have a final cause of death as soon as I determine it."

"You know my number." Lindsay replied.

"Let me know if and when you get an ID." Marty requested.

"Will do." Lindsay collected her evidence and left.

After checking the clothing and shoes for trace or anything else that would be useful and turning up nothing she went to the piece of paper.

His fingerprints had been run through AFIS with no matches so the paper was all she had to go on.

She wrote the number out on another sheet of paper. She checked the paper for a watermark but found none, and then she printed it.

A perfect thumb print appeared but unfortunately it belonged to the victim.

"Lindsay." Mac came into the room.

"Hey Mac."

"I heard you caught a case."

"John Doe in an alley. Preliminary cause of death is a heart attack. He had no wallet on him so he could have been mugged and dropped dead from the shock."

"Let someone know if you need any help." Mac told her.

"Do you keep things in your underpants?" Lindsay asked.

"Excuse me?" Mac was a little shocked by her question.

"I didn't mean that exactly the way it came out. Trace, AFIS, missing persons all drew a blank, the only think I have to go on is a number written on a piece of paper Marty found in his underpants."

"Looks like a bank account number." Mac said looking at it.

"I'm going to run it because otherwise I'm stumped."

"I have nothing other than a number which isn't a bank account number or a phone number there is no other evidence to say this guy didn't fall down with a heart attack all on his own." Lindsay told Flack.

"There's no way to ID him?"

"At this point no. Unless someone reports him missing he'll stay a John Doe. I'll keep trying to figure out the number but for now, its natural causes." Lindsay replied. "What did you fall in the pond?" Lindsay noticed a slightly bedraggled and damp Danny walking towards them.

"Don't ask." Danny replied.

"He slipped on our murder weapon." Hawkes said. "He caused quite a splash."

"Please tell me you have pictures." Flack begged.

Danny scowled and stomped off to change.

"Lots, he was slashing around like a baby."

"I'll let you know if I get anything on this number." Lindsay told Flack and disappeared off in the other direction.

"I think there is trouble in paradise." Flack stated.

"Lindsay told her brother a "friend" was taking her to a Yankees game, Danny made a joke and Lindsay said they didn't need to put labels on their relationship yet and Danny agreed with her."

"Ouch. He should know better than that." Flack stated. "I'd better get back to tracking down my John Doe."

"And I have to go and dry out this gun."
