Uncertainty Rules is the sixteenth episode in the sixth season of CSI: NY.
The team must unravel the series of events from a wild night for a group of friends--a night which resulted in the massacre of four people in a hotel room and a madman wandering the streets covered in blood and wielding an axe.
A disoriented young man wanders into the street covered in blood and wielding an axe. The police take him down with tasers, and when Mac and Flack go to the hotel room he was staying in, they find the bodies of four people: two men and two women. Flack interrogates the young man, James Roberts, who claims he was attacked by clowns and doesn’t remember anything after that. Flack asks what kind of drugs James took, and though clearly high, James insists he doesn’t remember doing any drugs. Flack scoffs at James’ story of recalling swimming with sea horses and throws his hands up in disgust. Mac and Stella watch from behind the mirror and posit that James must have taken LSD. Stella tells Mac that James is a physics major at Chelsea University. Mac notices eleven missed calls from someone named Sara on James’ phone, and has the girl brought in. Sara insists that James has never done drugs in his life, and says he was out the night before with his two best friends, Mark Turner and Daniel Vaughn, to celebrate his 21st birthday. The girl asserts that James is not the partying type. Danny and Hawkes collect evidence from the hotel room, noticing a gap in the blood splatter pattern on the wall, indicating a person other than the killer was in the room. Hawkes also finds a gun. Danny is able to at least confirm part of James’ story: he finds clown masks in the room with DNA from James’ friends, indicating they surprised him in costume. The two women are identified as Jackie Wright and Lacey Deshane, but while all the men tested positive for LSD, neither woman did. Hawkes goes over the clothes, finding shampoo on James’ jeans and an unidentified substance on Mark’s shirt–but no blood splatter cast off on James’ shirt. Adam pieces together the order of events, and looking at the bathroom door, Stella notices there’s no blood on the edge, indicating it was shut at the time of the murders. She and Danny go back to the scene and find a shower curtain with sea horses, and, recalling the shampoo on James’ jeans, realize he must have been in the bathroom at the time of the murders. He’s not the killer.
Mac questions James, telling him he knows that he didn’t kill his friends. He asks James about where he met the two girls, and James swears he doesn’t remember. He tells Mac there’s no way he would have done LSD, and gets increasingly agitated. Stella, Danny, Flack, Hawkes and Adam try to piece together the order of events of the boys’ evening. Danny notes that DNA hadn’t yet come back from a bite mark on James’ calf, but Adam has managed to recover a photo from the evening: the three friends at an assisted living home. Danny and Flack pay the home a visit and learn that the boys played bingo with some senior citizens and won some serious cash: $25,000. When DNA from the bite matches Calvin Moore, a 3’9 wrestler, Danny and Flack track him down and are surprised to find Calvin admitting he “did it” for a grand—until they learn that Calvin merely agreed to wrestle James. Calvin says the boys weren’t acting like they were on drugs, and doesn’t recall any women with them. Mac continues to try to jog James’ memory, taking him out of the station for a cup of coffee when James spots a poster of a bull and freaks out. He tears it from a vendor stand, remembering that he rode a bull the night before—one without a face. Flack tracks down the bar James was at and the bartender recalls James and his friends—and the two women that were with him. She admits that the girls might have put something in the three guys’ drinks. Flack calls Stella to tell her the news, and she reports that the substance on Mark’s shirt as antifreeze from a taxi. Stella and Danny head to the cab depot where they find a driver, Gerald Gordon, dealing with a heavily damaged cab. Gordon admits that the boys were in his cab—and not just as passengers. He let one of them drive the cab for $100, which ended in a crash. The guys paid him $1500 for the damage.
Stella and Hawkes go over the footage from the video camera in the cab and discover that the boys stopped to pick up the two girls randomly. Stella posits that the women saw the kind of cash the guys had on them and drugged them intending to steal it. Stella notices Jackie slipping a gun in her purse. Danny and Flack go to the building where the girls were picked up and knock on the door of sleazy drug dealer Rufus Knox, who is nursing a nasty gunshot wound to the face. Danny and Flack surmise that the girls sold drugs for him and decided they wanted out, shooting him in self-defense to get out. Rufus insists he has “nothing but love” for the two women, and says he heard their killer was caught. Danny and Flack tell him that the guy they caught proved to be innocent, but they have nothing to arrest Rufus on… until Hawkes gets DNA results back on epithelials from the axe that match Rufus. Stella, Danny and Flack go back to arrest the drug lord, but he’s not at his apartment. Rufus and his bodyguard have tracked down Mac and James, and take aim, but Mac spots them first. He takes down the bodyguard and James gets a hold of his gun, recognizing Rufus as the one who killed his friends. He prepares to fire the gun, but Mac talks him down and arrests Rufus. Stella and Mac muse about the sad twist of fate: Rufus went looking for the women that James and his friends randomly picked up, and killed everyone but James, who was tripping in the bathroom. Mac reassures James, who feels guilty about what happened to his friends. Mac reunites the boy with his parents and girlfriend and watches as they leave the station together.
