CSI: Crime Scene Investigation (2000 - Present): Drops' Out

Grissom and Nick are first at the scene after a platinum blonde woman is shot in a dark room. The vic has two entry wounds, two exit wounds, both through-and-throughs. There are seven empty bullet casings on the floor. The CSIs suspect that she might have interrupted an armed burglary because the drawers have been rifled through. Gil sees a strange, circular blood drop on the floor, far from the victim that dropped to the floor through a whole in the ceiling. Nick orders the rest of the CSI team check the apartment above.
