bystander before speeding off. Lewis pursued, and Kellerman and Narcotics Detective Terri Stivers hopped in a vehicle moments later. They sped back to Mahoney's condominium and stormed in to find a disarmed Lewis on the ground, facing his own gun in Mahoney's hand. Kellerman gave three warnings, and Mahoney lowered, but did not drop, the gun. Kellerman then prepared to read Mahoney his rights, only getting as far as "You have the right to remain silent" before he shot Mahoney once, killing him. The detectives wrote up the incident as if Mahoney had had the gun raised, and the shooting was eventually ruled clean. While Kellerman convinced himself that what he did was justified, Stivers was not so convinced, and Lewis eventually came to doubt it as well. Mahoney's empire was salvaged by his sister Georgia Rae (Hazelle Goodman), who was convinced that Kellerman had murdered her brother and sought revenge, initially attempting to blackmail Kellerman with non-existent video footage of the shooting (through which she was convinced that Kellerman had killed her brother in cold blood) and eventually deciding to sue the city through the help of a corrupt judge, Gerald Gibbons (Rick Warner), on her payroll. Kellerman later learned that Gibbons was being investigated by the FBI, and after the judge dismissed the lawsuit, Kellerman publicly called him out and urged him to give up Georgia Rae. Fallout Gibbons was found stabbed to death shortly afterward, with evidence pointing to Georgia Rae's son, Nathaniel Lee "Junior Bunk" Mahoney (Mekhi Phifer). Junior Bunk was brought in for questioning, but refused to implicate his mother. While waiting to make a phone call, he seized a weapon from a desk drawer and started a firefight in the Homicide squadroom. Although he was ultimately shot dead by Bayliss, Lewis, Kellerman, and Giardello, Detectives Gharty and Ballard were injured and three uniformed officers were killed. The police went out in force, and Bayliss subsequently took a bullet to the ribcage while shielding Pembleton from a shooter. Georgia Rae was eventually found dead, killed by her own people. After Stivers told Giardello that the Mahoney shooting was not as it seemed, Giardello directed Detective Frank Pembleton to find the truth. Pembleton and fellow detective Paul Falsone interrogated Lewis and then Kellerman, who eventually admitted that Mahoney had lowered the gun before being killed. Giardello then offered Kellerman a choice. He could face a jury
