Investigators locked in a four-week manhunt for alleged police killer Dezi Freeman could soon face the prospect of “drawing a line in the sand” as resource restraints and costs pile up. Freeman, also known as Desmond Filby, allegedly fatally shot Neal Thompson and Vadim de Waart-Hottart at Porepunkah on August 26. The 56-year-old has been on the run since, fleeing into dense bushland from the town about 300km northeast of Melbourne. There comes a point when management must consider the hard decision to withdraw, retired Victoria Police detective senior sergeant Charlie Bezzina said. With the police operating budget already surpassing $10 million for pro-Palestine demonstrations in Melbourne, Mr Bezzina said the added blow from the Freeman search had put costs under significant pressure.
