Las Vegas

Grissom sat in his office, feeling as miserable as he could ever remember. This was the sixth body found and they were all linked. He knew they had a serial killer on their hands, and they were no closer to finding it than they were when the first body showed up.

The murders were brutal. Young women between the ages of 17 to 24 had been abducted and were missing for about two weeks before they showed up in the desert, eyeless. They hadn't had a case like this since the Miniature Killer a few years back, and that didn't exactly end well.

Barely any trace evidence was found at the crime scene, since it was the desert. No footprints, no car tracks, only a couple hairs that weren't in the system.

Grissom hated asking for help from outside sources, but Catherine talked him into making the call. He just…hadn't gotten to it yet.

It's not that he didn't believe in profiling. He just didn't find it all too accurate. He liked hard DNA evidence that one could visibly see. Profiling just seemed so much like…guesswork.

Grissom stared at the card in his hand:

Jason Gideon

BAU unit Quantico

FBI

It followed with a phone number that Grissom had accidently memorized since they found the third body.

Grissom frowned, it was now or never.

He dialed and heard it ring a few times before he heard Jason on the other line saying, "Jason Gideon BAU."

"Agent Gideon, it's Gill Grissom from LVPD."

"Grissom," said Jason, obviously a little surprised. "How have you been?"

"Better. We have a serial killer on our hands."

There was a pause. "Are you positive?"

"Absolutely."

"Fax us the reports and we'll have it looked at. How many victims?"

"Six."

Jason sighed. "Well, he has been busy hasn't he?"

"It would seem like it."

Jason laughed quietly. "You know, I wouldn't have expected you to call us."

"Desperate times call for desperate measures I suppose," said Grissom, a little annoyed.

"Well, as I said, we'll have the case reviewed, but I don't think you'll have to worry. I don't think we have a case as dangerous as this. Seems like your guy kills fast."

"Thank you, Agent. I appreciate it." And Grissom did. Whether he believed in it or not, he would admit that the team needed help, even if Sara though otherwise…

"I'll call you when I find out."

The two hung up. Grissom closed his eyes and pinched the bridge of his nose. He had met Jason Gideon at a seminar he had in Vegas a few years ago. He had brought along some kid with him who looked like he still belonged in high school. Turned out he had three PhD's. Imagine that…

Anyway, Grissom had not been convinced by the idea of profiling and he and Gideon had had a long discussion on DNA evidence vs. profiles. The whole time, the kid had watched them, arms crossed, shifting nervously from foot to foot. He obviously had a high opinion of Gideon.

The conversation ended and Jason had given Grissom his card, "Just in case," he said, before leaving with the shy kid following behind him.

Like he would ever use this, Grissom had once thought. However, he never got rid of the card.

Who knew? One day it might be helpful. And that day was now.
