Dezi Freeman manhunt hits grim milestone

The manhunt for suspected cop killer Dezi Freeman has now hit the one-month mark, with no sign of the elusive fugitive in all that time.

Freeman, 56, has evaded a search operation involving hundreds of police since he disappeared following a shooting at his home in Porepunkah, in regional Victoria, on August 26.

Two police officers, Neal Thompson and Vadim de Waart-Hottart, were killed in the ambush, while a third officer was wounded.

Freeman, who police accuse of carrying out the ambush, is believed to have fled the property, still heavily armed.

Police have issued a historic $1 million bounty for information leading to his arrest.

Freeman has been described as a skilled outdoorsman with good bushcraft.

However, it's also been speculated he could be receiving assistance from somebody in the local community.
