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.

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

The police were part of a group of 10 officers seeking to execute a search warrant on the property.

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.

Hundreds of officers remain involved in the search for Freeman, covering a wide range of bushland including Mount Buffalo National Park.

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.
