La squadra viene chiamata per indagare su una sparatoria avvenuta in un quartiere di Las Vegas normalmente molto tranquillo. Due le vittime sull’asfalto: Bill French e Jason Morley, un ragazzino di sette anni. Un ferito, Priscilla Hatcher, apparentemente il vero obiettivo dei killer. Le indagini prendono una brutta piega quando Langston e Riley vengono presi in ostaggio dai malviventi e rinchiusi in uno scantinato. MATERIALE Synopsis Langston and Riley are taken hostage during the aftermath of a shootout in an usually calm Las Vegas community. Full Recap Following a training exercise addressing hostage situations, the team is called out on multiple 419s in a quiet Las Vegas neighborhood. Two people are dead, the victims of fatal gunshot wounds: the street neighborhood watch captain, Bill French, and a seven-year-old boy named Jason Morley. The apparent targets were Priscilla Hatcher, whose home was broken into, her son, Reggie, and nephew, Frankie Kirkland, but only Priscilla has been found and is on her way to the hospital. .38 caliber bullets from a 9-millimeter gun are recovered from the street and Catherine posits that the neighborhood watch captain may have fired at one of the suspects.

Nick finds a book of checks with Reggie's address on them indicating he lives right down the street--in the house the SUV was parked in front of. Meanwhile, Brass gets a lead on a shooting victim who was dropped off at Desert Palms Hospital. By the time Brass and Catherine get to the hospital, the man, Marcus Garfield, is dead. From distinctive tattoos on his face and body, Brass is able to identify the man as a member of the Snakebacks, a dangerous Vegas gang that deals in drugs. Catherine wonders if Reggie was involved in dealing drugs in some way, and Brass says that if he was, he and his cousin are probably dead. Back at the lab, Catherine and Hodges go over surveillance footage from the hospital and see Marcus Garfield tossed out of an SUV with tinted windows. They run the plates, but the car belonged to Garfield himself. Riley recovers...
