Recently discovered police files reveal that the million-heavy, Australian businessman Ron Medich planned to assassinate his former colleague Michael McGurk long before he finally shot him in front of his house last year.

The charged convict Medich officially denies having anything to do with the murder of McGurk and appealed against the judges that sentenced him guilty.

The new police documents now reveal that Medich articulated his assassination plans in front of the business friend Mr. Gattellari and was even searching for a professional killer.

Before McGurk was murdered, the victim himself even articulated suspicions to a colleague that someone was planning to kill him due an argument about finances.

The police document reports: "This threat was made with respect to business disputes between McGurk and Ronald Medich. McGurk told this witness that should anything happen to him, then Gattellari's name should be passed on to police as the one responsible".

The police files reveal that the murder of McGurk has been discussed in several conversations between Medich and Gattellari. The latter thus represents one of the chief witnesses in the murder case.

Medich, known to be a Loabor Party supporter, made several donations to the party before his charge that amount to a sum of $250,000. A spokesperson of the Labor Party of New South Wales announced that the money of the sentenced killer will be rejected for campaigning use and given to charity.
