THE four-month trial of former bikie leader Mahmoud "Mick" Hawi, who is charged with murdering a man at Sydney Airport in 2009, entered its closing phase on Wednesday. Mr Justice Robert Allan Hulme began summing up the case to the jury in Sydney West Trial Courts, Parramatta. Hawi, 31, of Bexley, once one of the heads of this area's Comanchero Motorcycle Club, has pleaded not guilty to murdering Anthony Zervas, whose brother was a Hells Angels member. Justice Hulme was expected to continue his summation of the case until Friday, after which the jury will retire to consider its verdict. Five other Comanchero members or associates are also standing trial co-accused of the same murder. During the trial, medical experts gave evidence that bollards, a pair of scissors and a knife found in a drain might have played a part in the death of Mr Zervas. The court heard the injuries he suffered included internal bleeding, stab wounds and a fractured skull and that his head might have been stomped on or hit by a bollard. Justice Hulme said most of the available closed-circuit video footage of the attack was "average" and "quite poor". The jury should not draw any inference from the fact that a particular camera was not working during crucial moments, he said. Justice Hulme said part of the Crown case was that the Comancheros intended to inflict grievous bodily harm on Mr Zervas, who was one of five Hells Angels or associates at the airport. The jury had to decide if there was a joint criminal enterprise. The trial continues. Hire-car driver was drunk A CRONULLA father-of-six who pleaded guilty to a mid-range drink-driving offence allegedly told police who pulled him over for a random breath-test he knew he had had too much to drink. Graeme John Purcell, 58, of Cronulla, was stopped by police in August after attending Cronulla Bowling Club with his wife. His solicitor said the couple had four children still at home and his client relied on the success of a Cronulla car hire business to get "the whole family out of a financial quagmire".
