assassin working for Carlos Guerrero. Norberto was dispatched to kill Officer Ricky Simmons when Carlos discovered Simmons was an undercover cop trying to infiltrate his organization. Norberto did so by throwing him off a freeway overpass, but not before Ricky bites and takes a chunk of flesh out of Norberto's arm. Norberto then checked Ricky's phone, and discovered he had been in constant contact with his wife, Kara, and to prevent information leaking to the police, Norberto went to the Simmons residence, and shot Kara in the back and departed, but not before his bleeding arm left a drop of blood at the scene. When Kara succumbed to her injuries in hospital, her secret lover, Doakes, was driven to investigate harder and soon discovered the DNA trail and arrested Norberto. LaGuerta offered Norberto a more lenient sentence in exchange for providing enough evidence to bring down Guerrero, and he seriously considered this, but somehow Guerrero knew, and arranged for another one of his assassins, a paid off prison guard, to bring Norberto to the prison's showers, where he stabs Norberto to death. The death was blamed on an unnamed prisoner. Kara Simmons (Maureen Moldoon) was the wife of Ricky Simmons. Evidently, she became unhappy with her relationship with Ricky and became unfaithful to him by sleeping with Sergeant James Doakes. After her husband was shot for working undercover, Carlos Guerrero sent a man, Norberto Cervantes, to their house and shot her in the stomach, she tried to call her husband during the attack. Soon after, María LaGuerta and James Doakes arrive on the scene to find her gutshot. James Doakes becomes very concerned with her recovery and stays by her side while she is in hospital, to the suspicion of LaGuerta, who later confronts him with her theory that he is sleeping with her, to which he admits that he was. Doakes is shown to be very upset and vengeful regarding Kara's death. Matt Chambers (Sam Trammell), also known as Matt Brewster and Matt Rasmussen, is a 35-year-old alcoholic.
