On 26 January 1865, Hall, Gilbert and Dunn were at Collector, south of Goulburn. While Hall and Gilbert were robbing the hotel, John Dunn stayed outside to watch for the police. Most of the police were out in the bush searching for the bushrangers. Policeman, Constable Samuel Nelson, was told the bushrangers were at the hotel. He told his wife he would "have to do his best". As he walked up to the hotel Dunn shot him in the side of the body, and then fired two shots into his face. Nelson was the father of nine children. One of the children saw the shooting. The bushrangers stole Nelson's gun, and his personal belongings and then left the town. During the next three months, the gang continued to rob from farmhouses and mail coaches.
