with Sergeant William Cooper, 43, and Constables Frederick Jordan, 26, and Percy Tulloch, 35. After a short conversation inside his house, Graham shot and wounded Sergeant Cooper and Constable Best after Sergeant Cooper apparently reached to disarm Graham. He then fired at Constables Jordan and Tulloch as they ran into the house, killing them both instantly with the one bullet. When the badly wounded Cooper attempted to leave to obtain help, Graham shot him dead on the path in front of the house. Best was shot once more after allegedly attempting to plead with him, and died three days later. Graham also fatally wounded a field instructor for the Canterbury education board named George Ridley, who had entered Graham's property to assist any wounded along with an armed local, whom Graham threatened and disarmed. Graham then fled his house, armed with both of his Winchester rifles, his 7mm Mauser Rifle, the .303 rifle taken from the local who had accompanied George Ridley into Graham's property, and a .32 ACP Colt Revolver stolen from Sergeant Cooper's body. Manhunt and death Returning the next evening to discover three members of the Home Guard in his house, Graham opened fire and killed home guardsmen Richard "Maxie" Coulson and Gregory Hutchison in a gunfight. During that engagement, he was wounded in the right shoulder. The ensuing manhunt was the biggest in New Zealand history. It was overseen by Commissioner of Police Denis Cummings. More than 100 New Zealand Police and several hundred New Zealand Army and Home Guard personnel searched the area for Graham for 12 days, with orders to shoot on sight if they found Graham armed. On 10 October, both of Graham's Winchester rifles and 800 rounds of ammunition were discovered. Blood was discovered on one of the rifles, suggesting he had been wounded. In the next few days, Graham's blood-soaked shirt and the .303 rifle he had stolen earlier were recovered, and after 9 October, he was sighted numerous times by home guardsmen and civilians and, on at least three occasions, was fired upon whilst attempting to return to his home or simply walking in its vicinity. On at least two occasions, cattle on nearby farms were found slashed or shot, and on at least one occasion, a dead heifer was found with meat taken from it. On 17 October, a farmhouse belonging to Henry Growcott, a childhood friend of Graham's,
