Percy several times in the back as she ran down the street in terror; she died a few hours later at the scene. He then turned towards three children. He killed the two boys, Leo Wilson and Dion Percy. The boys' sister, Stacey, was critically injured by a bullet to her abdomen, but survived. Ross Percy, the children's father, who had been driving them home after a day fishing when they saw the fire, was fatally shot in the head. Next, Aleki Tali was killed. Gray then entered the home of Tim Jamieson, killing him and another elderly local, former Green Island mayor Vic Crimp. The next victim was James Dickson, who was looking for his dog. Eva Helen Dickson, James' mother, and neighbour Chris Cole went into the road to see what the noise was. Gray shot at both of them, wounding Cole who was in a phone booth calling the police and forcing Mrs. Dickson to dive for cover. Mrs. Dickson, who had recently had a hip replacement and was unable to walk without assistance, pulled herself along on her stomach using her arms and feet in a ditch to get inside and called 1-1-1 (the emergency telephone number). She then crawled back to Cole to tell him help was coming. By this stage, it was getting dark and the dispatcher advised her to stay inside. Mrs Dickson later received the George Medal for bravery. Help arrived too late for Cole, who died in the hospital. First responders The first armed police officer to arrive was Sergeant Stewart Guthrie, officer in charge of Port Chalmers police station and an NCO in the Armed Offenders Squad (AOS). He came armed with a Smith & Wesson Model 10 police revolver (front-line police in New Zealand do not routinely carry firearms). Guthrie enlisted the help of Constable Russell Anderson, who had arrived a short time earlier with the fire service. He armed Anderson with a rifle belonging to a resident. With darkness approaching, the pair moved through the township to Gray's house, where Guthrie deployed the constable to cover the front while he moved to cover the more dangerous rear of the house. Detective Paul Alan Knox and two constables arrived, starting the first step of the "cordon, contain, appeal" standard police strategy for armed offenders. Guthrie observed Gray and relayed his movements inside the house to the police communications centre.
