As Grissom walked into the basement of an old warehouse he was shocked by what he saw. A man was in the middle of what looked like a razor wire cage. Grissom stared in shock at the body. David spoke first "Based on the rate of decomp he's been dead at least 3 weeks." Doc Robbins began to speak "Cause of death was massive blood loss. He cut himself so deep we found traces of stomach acid on the floor." Grissom continued to look at the body with his flashlight when he heard someone coming down.
He looked up to see Greg ducking down to avoid the ceiling. Greg looked at the body and started to laugh. "Oh my God, Nicky get your ass down here, you gotta see this!" Grissom stared at the young man with a stern look on his face. "Is there anything funny about this Greg?" he asked. Greg looked startled. "No, of course not I just never thought I'd see anything like this unless I was in a Saw movie or something." "What's that supposed to mean?" he asked Greg. Nick started to enter the basement, he let out a silent laugh and looked at Greg. "Holy hell man." he said staring at Greg. "Is there something you two know about this?" Grissom asked. "Looks like we got ourselves a jigsaw killer huh Greggo?" Nick asked. "Yeah, I guess so Nicky." Greg responded.
"What the hell are you two talking about?" Grissom asked confused. Greg began to explain "There are these movies called the Saw series, the first one came out in late 2004 and Saw IV was released in October. Anyway they feature a man known as the jigsaw killer. He takes people who he feels are taking their lives for granted and puts them through gruesome tests." "This was the first test in the first movie." Nick told Grissom. "Did you guys find a tape player?" Greg asked suddenly. Grissom looked surprised. "Yeah, we did." "Did you listen to it?" "Not yet" Nick took over "The vic most likely tried to commit suicide by slitting his wrists but our killer thought that the vic just wanted some attention, so he placed him in this room filled with razor wire. If the vic wanted to live he would have to go through the wire and cut himself again, but the door would close in about 2 hours if he didn't make it out in time he would die anyway."
Grissom grabbed the evidence bag which held the tape. He pressed play. An eerie, dry voice filled the room. "Hello Jack, you are a perfectly healthy, sane middle class male yet last month you ran a straight razor across your wrists. Did you hurt yourself because you really wanted to die or did you just want some attention?" Grissom started at Nick and Greg whose faces were both somber. "You'll show me tonight, the irony is that if you want to die you'll just have to stay where you are but if you want to live you'll have to harm yourself again. Find a path from the razor wire to the door. But hurry at 3:00 the door will lock and then this room will be your tomb. How much blood would you shed to stay alive Jack? Live or die, make your choice."
As the tape plays a flashback of the victim is shown waking up then shaking the wire and screaming. He tries to go through the wire and screams in pain as the wire continuously cuts his skin. He is dying as the door shuts. Nick and Greg move closer to the victim. They notice a jigsaw shaped piece cut out of his skin. "Hey Grissom, come check this out." Greg tells him. Grissom moves toward the body and notices the jigsaw piece. "It's supposed to be a symbol that the vic was missing the survival instinct." Nick says. Grissom gives him a look. "He mentions it in the second movie." They continue to search around for evidence but can find nothing conclusive. With some help the body is removed and the door shuts on the room that held the first Jigsaw victim
