Case profile – Peter Timmermanis

Posted on 19/07/2021

Can you help solve the suspected murder of Peteris (Peter) Timmermanis?

When he was first reported missing by his sister in 1991 investigators had little information about the circumstances of his disappearance.

That changed in 1995 when a person close to him contacted police about the missing 31-year old’s activity in the cultivation and trafficking of large cannabis crops.

It is now believed that he was killed at or near a Gleesons Landing cannabis crop site and his body dumped in a well somewhere on the lower Yorke Peninsula.

An associate has told investigators that on 17 July 1991 he and Mr Timmermanis were transporting about $300,000 of cannabis from Gleesons Landing but became separated on the journey.

The associate later went to premises in Yorketown and located the truck with Mr Timmermanis’ keys, wallet and other personal possessions inside. The cannabis had been removed from the back of the truck and Mr Timmermanis was nowhere to be seen.

Earlier that day Mr Timmermanis had told his sister he was going away and would be back in a couple of days. When he failed to turn up on 7 August she reported him missing.

Further inquiries revealed that he was due to depart for Cyprus on 25 July with some other associates, who are suspected of being involved in the cannabis trade.

While he did not show up for the flight, a relative of one of the associates was on hand with his bag and ticket ready to take his place and travel to Cyprus.

In 1996 police located evidence that a cannabis crop had been at Gleesons Landing. In 1997 investigators went to the Wool Bay Jetty to search for a firearm which had reportedly been thrown off the end of the jetty and had been used to kill Mr Timmermanis, however nothing was located.

In 1999 police went back to Gleesons Landing and searched a number of wells in the area, following information that he had been murdered and his body dumped.

A $200,000 reward is available for anyone providing information which leads to the apprehension and conviction of the person or people responsible for Mr Timmermanis’ death or the recovery of his remains.
