Bow hunter Guy Newman jailed for killing associate with arrow A BOW hunter who murdered an associate with a lethal arrow during a confrontation over stolen power tools has been jailed for 21 years. Guy Newman, a 36-year-old automotive engineer, shot associate Trent McNamara through the back with an arrow loosed from his composite bow while questioning Mr McNamara about $20,000 worth of tools stolen from a large container at his Club Terrace home. While sentencing Newman to a minimum 17 years' jail today, Supreme Court judge Justice Lex Lasry said the killer drove to a Bairnsdale home to talk to Mr McNamara, who he believed may have been responsible for the May 2011 theft. Newman had packed his bow, a quiver of arrows and a type of sickle because he felt personal safety might have been an issue. While Newman had argued he shot and killed Mr McNamara in self defence, a jury at his trial rejected that. Newman was found guilty of murder. Justice Lasry said it was clear the jury based its decision on the fact Newman tried to clean the crime scene and drove the body to another property where he made certain admissions to another male associate. The judge said the jury must have also accepted evidence that showed Mr McNamara was shot through the back, rather than through his collarbone. Justice Lasry said Newman fired the lethal arrow at close range when Mr McNamara was not armed and not attacking him. The judge said he accepted the crime was a spontaneous reaction rather than a premeditated act. Justice Lasry said he was struck by the futility of Newman's crime and its ramifications. Newman has already served 793 days in custody.
