$600,000 reward offered over murders of Jeff Mundy, Trevor King and Robert Atkins

It has been revealed murder victim Trevor King, whose death has been linked to three separate killings – only started taking drugs to lose weight. A $600,000 reward is now on offer.

A man who was murdered before being dumped at West Lakes only started taking drugs to lose weight, his family say.

Trevor King’s death was staged as a drug overdose, but was last week declared a murder linked to two violent killings in the southern suburbs.

In a statement provided to 7NEWS Adelaide, Mr King’s family said their loving memories together will “forever be tainted with the pain of losing him by the hands of evil”.

Mr King was a father and a business man.

A $600,000 reward was yesterday announced in a bid to encouraged anyone with information on the three brutal murders to come forward.

Deputy Commissioner Linda Williams announced on Thursday Task Force Southern – one of the largest investigations of its type, involving 42 detectives – would reward up to $200,000 for information that leads to a conviction of those involved in the alleged murders in the case of Jeff Mundy, Trevor King and Robert Atkins.

“These were people who walked and lived in our community and should still be doing that today,” Ms Williams said.

“We are keen to help the families understand what has happened to their loved ones because they have a right to know, and furthermore those who did this need to be held to account and shouldn’t be out in our society.”

In December, Task Force Southern was launched to untangle a web of brutality in Adelaide’s southern suburbs that left at least three men dead over unpaid drug debts.

The bodies of Mr Atkins and Mr Mundy yet to be located. Police are also reviewing hundreds of drug overdoses from July 1, 2019, to see if they were actually murders.

In its first fortnight of operation, a total of 33 calls have been made to the task force.

Police believe Mr King and Mr Atkins were both detained and tortured before they were murdered.

All involved victims and suspects believed to have been associated with the methamphetamine scene. Police say there are up to 15 offenders and there could be additional victims.

Ms Williams hoped the reward encouraged anyone connected to the drug scene to come forward with information.

“If the motivation for somebody is to get out of a bad way of life and this assists them to do that, that’s fine,” she said.

“Some of these people have made bad choices and they don’t know how to get out of it or don’t see a way, this may be a way that they can do that.

“We will look at providing immunity on a case-to-case situation if that is a concern to a person.”

Additional rewards could be offered if further murders are identified and the information provided leads to a conviction or the recovery of the bodies of Mr Atkins or Mr Mundy.

If anyone has information about the murders of Mr Atkins, Mr King or Mr Mundy, they are asked to please call Crime Stoppers on 1800 333 000 or go online at www.crimestopperssa.com.au.
