"Jason Scott Troy…" Mulder sat and shared info from files and papers from the bureau. "Born on January 9, 1970, the son of fashion model and actress Helen Troy, father unknown; his grandfather is James Peter Reason, the philanthropist andowner and chief stockholderof Olympian Industries, a multi-million dollar company…"

"Nice to have a rich grandfather…" Warrick mentioned across from Sarah.

"Twelve years ago, Troy lived in San Marcos, Texas…" Mulder continued. "Where the Bureau was investigating murders of a… cult like nature."

"Human sacrifices?" Grissom guessed.

"Correct…" Mulder continued. "A group of modern day Hecate worshippers. She was an ancient goddess of the underworld…"

"Troy was a member of the cult…" Sara responded.

"Troy was our informant." Mulder pressed on. "He helped us to expose the activities and bring the cult to trial. We sent him here to Las Vegas under the witness protection program and now he's dead."

"I really doubt Kendall and Sadler were sent to silence him after the fact." Grissom reacted with fault. "They wanted to rob him. They held him at gunpoint and took him of his money. They killed him because he fought back."

"Mr. Grissom…" Mulder could tell clashing with this guy was not a feud he wanted to start. "A Federal informant has been killed. My superiors want me to look into your investigation."

"Then let us do it." Grissom continued as Sara and Warrick watched speechless. "I'm sorry, but I've had bad experiences with you guys from the bureau."

"I know of your experiences with the FBI from the Strip Killer case." Mulder had done his work. "Believe me, Agent Richard Culpeper is not indicative of the FBI. I'm only here to observe and report." He turned to Warrick. "Have you formulated a sequence of events from the previous night?"

"Yeah, I got it punched this morning." Warrick had the computer simulation ready. "This is based on the cumulative evidence from the blood splatter on the lot, partial security camera evidence from across the street, measurements of the tire skid marks and gunshot triangulation at the cemetery." He used a remote control to switch on the screen. Computer generated graphics portrayed the simplest version of the street where Troy had died. A non-detailed figure in flesh tone represented Troy while similar figures played Kendall and Sadler in brown and white. Warrick narrated the simulation created from the gathered evidence.

"The victim departs the store at 10:03 and travels south down Puckett." He described the animation. "Sadler had flash burns on him proving he shot first from behind the lot and the bullet drops Troy. Kendall then gangs up on Troy forcing him to the ground. As Troy fights, he kicks Kendall back and opens himself up for another shot from Sadler firing to the chest this time…."

Sara narrowed her eyes and tried to understand inhumanity to man.

"Troy, however, is still alive." Warrick answers. "Blood splatter shows he managed to slide sideways and backward five feet to where Sadler pulls out the second gun we found in the car and fires point blank into Troy's head. Troy, however, is still conscious and losing blood. His heart was still beating."

"He's made of tough stuff." Sara responds. "Sadler and Kendall never had anyone confront them like this. Troy might have lived if he hadn't fought back."

"Sadler and Kendall depart the scene in the Monte Carlo heading south up Puckett at fifty miles an hour." Warrick continued as a computer graphic boarded by animated figures raced before them. "They gradually increase their speed to sixty and then make this odd swerve just before the end of the street at Harmon."

"Looks as if they tried to hit something in the center of the road." Mulder noticed.

"There was nothing there." Sidle revealed. "We checked the car bumper for impact evidence. We found nothing there."

"Something they hallucinated?" Grissom answered.

"They are doing a full seventy five miles an hour when they crash the fence and the drag of the cemetery slows them to fifty six before they finally stop." Warrick continued. "Surviving the impact, they getout of the car and reach this area where they are standing in the epicenter of the shots fired. I found eleven shots buried in tombstones, trees and a mausoleum."

"What were they shooting at?" Mulder asked.

"Look at the simulation…" Grissom pointed to the screen. "All the shots were fired at the same level in a directionless field around them. They weren't shooting at one thing; they were firing at multiple hallucinations coming at them at all sides." He paused. "But something physical drowned them underground."

"What do you think they think they were shooting at?" Sara wondered.

"Ghosts?" Warrick answered. "Harmon Cemetery has had a reputation of being haunted back to 1923."

"I don't believe in ghosts." Grissom answered. "But look at the range of their shots. They were firing indiscriminately at something coming at them at chest level. Why would they do that?" Above him, the door to his office poked open and lab tech Greg Sanders looked in. Fox Mulder noticed the headphones around his neck and Hawaiian shirt under his open lab coat.

"Grissom," He held up a file. "I found something odd from the toxicology on Troy's blood. I even ran it three times to explain it, but I can't figure out what it is." He handed over the file with the bravado that he made another big discovery. Tapping his glasses, Grissom read the files and tried to understand what he was reading. He looked back up to Greg to Warrick and Sara and then over to Mulder before looking back up to Greg.

"Surreal, ain't it." Greg answered.

"What?" Sara wanted to know. She took the file and shared it with Warrick for perusal. "An extra chromosome? Where does someone get an extra chromosome?" She looked to Grissom and then to Mulder who sat across from her without a response or an interest.

"You already knew about it." Grissom had another reason to hate Government agents. They were always keeping secrets.
