NSW teenage axe murderers in joint appeal TEENAGE axe murderers Matthew Milat and Cohen Klein will appeal their prison sentences together, a Sydney court has been told. Milat and Klein are appealing the severity of their sentences handed down last year for the murder of 17-year-old David Auchterlonie at Belanglo State Forest in November 2010. Milat, a great-nephew of serial killer Ivan Milat, was sentenced to at least 30 years, with a maximum term of 43 years. Klein was jailed for at least 22 years, with a maximum 32-year jail term. The Court of Criminal Appeal on Thursday heard Milat's and Klein's appeals should be heard jointly as there was a parity issue in relation to their sentences. The pair pleaded guilty to murder, with the court hearing Milat, then aged 17, had gloated about the killing the next day. You know me, you know my family. You know the last name Milat. I did what they do," he said. The axe attack took place in the same NSW southern highlands forest where Ivan Milat murdered seven backpackers in the early 1990s. Sentencing the pair last June, Acting Justice Jane Mathews said the victim was tortured and tormented before Milat fatally struck him with a double-bladed axe. "This was a thrill kill," she concluded. In other words, he (Milat) took the life of an innocent young man, who was unfortunate enough to be his friend. Registrar Michael Crompton adjourned the case for mention on July 4.
