Investigations have revealed the car was left at Deepwater Bend until midnight on Tuesday before leaving for NSW on Wednesday morning.

The car was found abandoned in NSW on Thursday.

Detective Inspector Tim Trezise said police now believed Mr Thompson may have been involved with “unsavoury” characters.

“We now suspect foul play was involved,” he said.

“The circumstances of Sam’s disappearance are quite concerning in that he’s just vanished off the face of the earth.

“It’s of grave concern to the family and we are doing everything in our power to locate Sam. He certainly wasn’t in any trouble that we’re aware of. As to his connections with unsavoury types, we’re still looking into that.”

Inspector Trezise said there had been no contact with family or friends and no use of social media.

He said Mr Thompson’s behaviour had been completely out of character.

Inspector Trezise said police had received a lot of calls to Crime Stoppers, and that police were now looking at the man’s ‘connections’.
