Neighbours say Senior Constable Evan Condon saved their lives as Anthony Young launched frenzied machete attack Murder victims Lou Dekens and Dave Young. THE final shot that police fired to bring down double murderer Anthony Young was at "point blank range" - a desperate action which neighbours say saved their lives. Russell Evans said his family were 30 seconds away from becoming the killer's next victims in the frenzied attack that had already claimed the lives of Young's brother Dave and Dave's partner Louise Dekens. A grateful Mr Evans thanked police on behalf of his wife Leanne and their four children. "Certain people are questioning the actions of police but they have obviously never been put in a situation as my family was," he said. The officer who stopped the killer in his tracks was Senior Constable Evan Condon, of Coolum station. Fellow officers say he faced the most confronting of scenarios with remarkable bravery and a textbook response.

Young, who had already slashed his brother and Ms Dekens to death, came at Sen-Constable Condon after the officer stepped from the passenger side of the police car. He and his first-year constable partner Jason Jupp, who was driving, had been called to a domestic disturbance. Sources say crazed Young was brandishing a knife in one hand and a machete in the other. He threw the knife at the officers and charged at Sen-Constable Condon wielding the other weapon. The officer quickly drew his gun and opened fire, but the attacker kept coming. "He only had seconds to react," a source said. The final shot was at point blank. When he finally dropped, he was so close Evan could have touched him. It would have been any officer's worst nightmare. Evan was very lucky to survive. Another colleague said it was a situation where a Taser would have been "useless." Russell Evans, neighbour to murdered couple David Young and Louise Dekens, speaks to the media. He said: "This guy would have run right through it in the state of mind he was in." Young remained aggressive even when paramedics arrived and put him in an ambulance. Sen-Constable Condon, an officer with about 10 years' experience, was described as "a top bloke" and colleagues have rallied to support him. "What Evan did was exactly what we are trained to do when confronted with such a threat," another officer said. Investigations at the Coolum house, where forensics officers are looking for clues, such as any medications or drugs Young may have been taking, continued yesterday.
