Episode 901 - For Warrick
Picking up the minute "For Gedda" concluded, Under-sheriff Jeffrey McKeen, who has just shot Warrick twice, calls in the shooting and claims he saw a white adult male fleeing the scene. Blocks away, Grissom hears the APB and rushes to the scene. He pulls Warrick from the car and begs him to hang on, only to have Warrick die in his arms. Catherine and Nick arrive soon after, stunned by the tragic news. McKeen tells Brass that he was twenty feet west of the alley when he heard the shots. He ran back to find Warrick wounded and the shooter fleeing the scene. He tells Brass he thinks it may have been Officer Daniel Pritchard. Grissom tells Ecklie he wants his team to work the case, and the supervisor acquiesces. Catherine finds a .25 casing and a pistol by the passenger side of the car, where the shooter appeared to have been standing. Nick wonders why Warrick would have rolled down the passenger side window and not his own. Grissom turns over his shirt, which is covered in Warrick's blood, and returns to his office to find a devastated Sara Sidle waiting for him. She's heard the news and offers solace and help. Sara and Greg go to Warrick's apartment, where they make a shocking discovery: Warrick had a son, Eli, with his ex-wife Tina, and he was involved in a custody battle for the boy. Nick discovers knuckle prints on the passenger side window of Warrick's car and tells Grissom and Catherine that he thinks the killer knocked on Warrick's window. Nick knows Warrick wouldn't have opened his window for Pritchard; he thinks McKeen is corrupt as well and, when he saw Warrick wasn't going to back down, killed him.
Grissom, Catherine and Nick test McKeen's story about hearing the gunshot and determine that from the position he claimed he was standing in, he couldn't have heard the shot over music that was playing in the street the morning Warrick was shot. Grissom goes to Brass with the information and Brass tells him he's always felt McKeen was a man who could be bought. They recall Warrick's assertions that someone higher up that Pritchard was involved in the murder of Lou Gedda. McKeen, certain no one is on to him, wants to get Daniel Pritchard, who he's been hiding at a seedy hotel, out of town. When Grissom comes to him with the team's suspicions, Ecklie advises caution and suggests that they need find concrete evidence, leading the CSIs to turn to the tiny .25 bullets. Mandy Webster is able to get a partial print off one of them--enough to match it to McKeen. The CSIs trace McKeen's phone calls to the hotel where he's been hiding Pritchard and storm the room, only to find it empty. Brass places a call to McKeen and keeps him on the phone long enough to get his location and learn he's on the road to Mexico. The police give chase only to find McKeen's car overturned after having smashed through a guardrail. Pritchard is dead inside, and Nick follows a blood trail to find a wounded McKeen--shot by a mistrustful Pritchard--who quickly realizes the game is up when Nick aims his gun at him. McKeen taunts Nick who fires a shot just to the side of McKeen. Brass and his men arrest the crooked Under-sheriff. Grissom and his team lay their fallen colleague to rest.
Episode 902 - The Happy Place
Catherine and Nick investigate the death of Sprig Grenigier, who dove to her death from the apartment she shared with her fiancé. Was it suicide or murder? Nick notices she received a call just before her death which is traced to a pay phone across the street from Sprig's apartment. Though they determine she was happy with her fiancé, the CSIs discover Sprig was trying to lose weight, and that she'd filed for unemployment after losing her job as a bank teller. She had been accused of stealing ten grand from the bank when she changed a customer's fifty dollar bills for a hundred hundred dollar bills rather than one dollar bills. To the bank, it looked like a scam Sprig was in on, but the her fiancé tells the CSIs she had no memory of what happened. The CSIs discover another bank teller who was similarly scammed and Catherine finds a connection: both women were seeing the same hypnotist to deal with various problems in their lives. Catherine and Nick pay a visit to the hypnotist, Viviana Conway, and witness how powerful her brand of hypnotism is. Catherine decides to compare the picture of the man who received the ten thousand dollars at each bank from security footage with Viviana's picture and get a match. The woman disguised herself as a man, went into the banks, gave the women hypnotic cues and stole the money. When Sprig figured out what Viviana had done, Viviana called her and gave her the cue for her honeymoon: to imagine herself in a bikini jumping into the ocean. Sprig did just that, only instead of the ocean she leapt from her balcony onto a bus full of people.
A woman is found beaten to death in an alley; the CSIs identify her as Paula Bonfilio and speak with her college-aged son, Scott, who tells them his mother gambled away his college money. He says she'd called him at 10pm the night of her murder after to say she'd be gone for the night. He also mentions she was with her two-year-old, Lexie. The CSIs launch a search for the girl while Archie studies video of Paula gambling at the Tangiers. He notices her with a man with glasses and then traces her to Pete's Pawn shop. The CSIs manage to locate Paula's car with a prostitute and find Lexie at a children's play center. The team recovers prints on Paula's car and traces them to Leon Slocomb--the man with glasses from the surveillance footage at the Tangiers. Leon admits to roughing Paula up and taking her car and kid to scare her into paying her gambling debts, but insists he left her alive. The CSIs uncover a surprising suspect when they catch Scott Bonfilio cashing in a $500 chip Paula won the night of her murder. Scott confesses to Grissom that Paula was his lover, not his mother, and Lexie was their child. At age 15, Scott ran off with Paula, his guidance counselor at school, but was dismayed to see their relationship deteriorate once he came of age and she turned to gambling for thrills. When she called him after lost the car and Lexie, he beat her in a rage. He believes Lexie is better off.
Greg calls Sara, still in town after Warrick's funeral, to the hospital where Tom Adler has just pulled the plug on his wife Pam, who had been in a coma for either years following a brutal beating and rape--a case Sara worked. Tom claims Tony Thorpe, the man who raped his wife, send him a note claiming he'd raped her again and was going to keep at it. Hoping to protect his wife, Tom pulled the plug rather than letting his wife suffer any more indignities. When Sara investigates, his story doesn't hold up: Thorpe is in a wheelchair, incapable of raping Tom's wife. Sara confronts Tom, and he admits that he just couldn't take it anymore--Pam was gone, and he was the only one suffering. Sara wonders why he couldn't just tell the hospital staff that, and Tom admits he was ashamed. The ordeal enforces Sara's belief that this life is no longer for her and she packs up and leaves both Las Vegas and Grissom behind.
Episode 903 - Art Imitates Life
Grissom and Catherine are called to a bizarre crime scene: a woman leaning against a light post is dead, possibly the victim of a lightning strike. Mandy Webster identifies the dead woman as Carla Perotti, a health care worker at Desert Palms. The CSIs, overtaxed because they're shorthanded, are given some relief in new hire Riley Adams, whose first day coincides with the arrival of a grief counselor named Patricia Alwick, who has been called in to help the team in the wake of Warrick's murder. Before Riley can get settled in, she's called out on a case: a jogger is lying dead on a bench. David Phillips determines that he's only been dead for about an hour and a half, but as was true of Carla, rigor has already set in. While both victims apparently died from cardiac arrest, Carla had no drugs in her system while the male victim did. Dr. Robbins also notices the livers of both victims are a reddish pink color, suggesting they may have died of gaseous asphyxiation. Hodges is able to identify the man as Harley Soon, who has a record for solicitation. The mystery deepens when a third victim is found, dressed as a businessman and posed hailing a cab. It's clear the CSIs have a serial killer on their hands.
The CSIs uncover a connection between their first victim, Carla, to an artist named Jerzy Scaggs. Jerzy paints eerie portraits of people that make his subjects appear as though they're corpses. Brass pays a visit to Jerzy, but he doesn't recall Carla, who modeled for him, and denies killing his models. Catherine posits that the killer is drugging his victims, posing them and then gassing them in a chamber so they die in the positions he wants them in. Another set of victims is found: two elderly people posed as bird watchers. While Riley scours an art blog, Greg finds tan fibers on the victims. When Brass uncovers Harley's juvenile record, which shows he was arrested at one of Jerzy's parties, Brass brings the artist into the station for further questioning. Brass shows him pictures of the murder victims and Jerzy recalls an artist who brought him similar sketches once, a subcontractor looking to win a city contract--as well as a contract to redesign Jerzy's studio. Nick pulls the city contract submissions and finds sketches from an Arthur Blisterman that match all five victims' poses--as well as a sixth, depicting a little boy on a bike. The CSIs step up their manhunt with the prospect of another victim, and their search grows even more urgent when a little boy goes missing.
The CSIs begin a desperate search for Blisterman, turning to the art blog Riley found after they discover a picture posted on it is one of Carla before the crime tape went up. With the help of the blog owner, the CSIs trace Blisterman's IP to a library and apprehend him there. The artist tells Grissom life is not worth living without beauty and that his victims were nothing until he made them extraordinary in his art. He's not afraid of dying, but he doesn't want to be forgotten. He refuses to give up the location of the place where he gases his victims and tells them it's too late to save his final victim, the young boy. Determined to find him, the CSIs trace the tan fibers Greg found to an abandoned warehouse and rush there only to find the little boy in the gas chamber. They quickly take him out, but he's not breathing. Frantic, Riley administers CPR--and at last manages to revive him.
Episode 904 - Let It Bleed
Halloween week finds Nick Stokes and Riley Adams responding to a liquor store robbery call only to catch the thief fleeing--wearing a police uniform! They give chase and Nick corners him in an abandoned hotel and the thief, with nowhere to go, jumps out the window. It's a fatal plunge, but when Riley leans over the garbage dumpster where he fell, she discovers the body of a young woman underneath his. While the rest of the CSIs investigate her death, Nick pursues the dead robber. He and Brass trace the uniform to a cop in town to testify who says his uniform went missing after he had it cleaned in the hotel he was staying in. Mandy Webster gets a DNA hit on the dead man's thumb, identifying him as Thomas Taylor of Bakersfield, California. The CSIs are able to link him to another man in town from Bakersfield, Barry Wunderlick--who happens to be in the drunk tank at the jail. Nick questions Wunderlick, who was arrested for drunk and disorderly behavior during his bachelor party. He was relying on his best man--Thomas Taylor to raise the ball money. Nick tells him Thomas made a genuine attempt: he committed four armed robberies in one night before Nick ended his spree.
A stamp on the thigh of the dead girl leads Catherine and Riley to the Dark Water Bar, a trendy club where Catherine is surprised to find her underage daughter. After sending Lindsey home, Catherine and Riley question club owner Craig Hess, who claims not to recognize the dead girl. The CSIs take a look at the club's security cameras, which contradict Hess's story: he's seen throwing her out of the club on camera. Grissom and Catherine examine the girl's body and find fresh needle marks in her arm and a white powder in her nose. Detective Vartann manages to ID the girl in the Homeland Security Database; she's Angela Marie Carlos, the daughter of a Colombian drug lord named Juan Ramone Carlos. The girl's aunt, Emelina, tells the CSIs that she'd sent her niece to school in Utah because Angela liked to party. She tells them that her brother will never forgive her. Greg questions Angela's friend Sylvie, who partied with Angela on the night of her death. Sylvie tells him that Angela told her that the owner of Dark Water Bar was a friend of her family and that she could easily get them in. She did, but the owner caught them and threw Angela out. Sylvie stayed behind and hooked up with a guy she met that evening. Catherine and Riley go back to Craig, suspecting he's in business with Angela's father, He claims ignorance--and also won't tell the women how he got Angela to leave the club. Back at the lab, Dr. Robbins shows Grissom that Angela's blood has hematized, a condition usually seen in advanced stages of decomposition--or some form of blood disease.
Lindsey Willows comes to her mother's office with a clean breathalizer test in hand: she can prove she wasn't drinking the night before. She claims her mother overreacted, but Catherine doesn't back down on the grounding. Hodges shows Grissom the substance in Angela's nose was a tranquilizer called atropine, not cocaine. Riley and Greg track Angela's cell phone to a garbage truck, but they can't tie its route in with Craig Hess. Wendy goes to Dr. Robbins claiming the blood he gave her is contaminated, but a retest proves the results are accurate. Wendy and Dr. Robbins tell Grissom that in addition to Angela's own B negative blood, there are two male donor samples mixed in: O negative and A positive. The latter is what killed her; it was completely incompatible with her own blood type. Fish scales on Angela's purse lead the CSIs back to Hess, who has a big fish tank in his club. He sends her the way of the busboy, Goya, who feeds the fish. The CSIs go to Goya's warehouse and discover him and his cohort, Joe, with a box of cocaine. They also find tubes that could have been used to transfuse blood. Catherine questions the men, who tell her Angela came to them for cocaine and ended up snorting atropine instead. When she passed out, they thought they could revive her by transfusing her blood, but they inadvertently killed her and dumped her body, hoping to frame Craig. Later in the evening, Grissom's phone rings: Goya, Joe, Sylvie, Hess and Ermelina have all been shot execution-style.
