TEXT: [EXT. LAS VEGAS CITY (STOCK) - DAY] [EXT. LAS VEGAS HIGHWAY (STOCK) - DAY] [SCENE_BREAK] [EXT. PARK - DAY] (A man is out jogging in the park. He follows the trail as he jogs.) (As he runs, he hears a low growl. He stops moving, then turns around.) [SLOW MOTION CAMERA] (A growling dog, teeth bare and aggressive, jumps and attacks him.) [SCENE_BREAK] [EXT. PARK - NIGHT -- LATER] (The man is on the trail, dead.) (Police Officers are there along with other emergency personnel. An Officer leads GRISSOM, WARRICK and NICK to the body. He takes one look at the body and reacts to it.) Officer: Aw, jeez. (The Officer leaves. GRISSOM glances at him then turns back to the body.) Warrick: (to the OFFICER) All right, Guy? (NICK kneels down next to the body and looks back up at GRISSOM and WARRICK.) Nick: I guess he won't be eating dinner tonight. (He snaps a photograph. GRISSOM looks around and sees something. He grabs WARRICK'S hand holding the flashlight and points it up to a point beyond the body.) Grissom: I think running man was attacked up there and then dragged or slid down here. (Up on the hill nearby are drag marks toward the body. NICK continues to snap photos of the body.) Warrick: Look at those wounds. Nick: He picked the wrong time of day to be running alone. Dusk is when the animals come out. Warrick: Yeah. From what I hear they carved out a piece of this valley when they made the park. (DAVID works on the body; GRISSOM continues to examine the wounds.) Warrick: (continues) Some mountain lion probably didn't like getting relocated. Mountain
