Queensland Police release suspect images in 2002 cold case murders, offer $1 million reward

Police have offered a $1 million reward for information leading to the conviction of suspects in two cold case murders.

Forensic artist impressions of two people believed to be linked to the suspected murders of two men from the Queensland–New South Wales border region 24 years ago were released by Queensland Police on Wednesday.

In 2002, 45-year-old Iain Stewart Hogg from Tweed Heads and 67-year-old Frederick Hugh Rosson, also known as "Slim Johnson", went missing.

Detective Sergeant Scott Chapman said the public should take a moment to look at the images of the suspects.

"Someone may recognise or know these men or remember something that seemed insignificant at the time but now could be important," he said.

"People who may once have been afraid to speak may no longer feel that way. It is never too late to come forward."

Last reported sightings

Mr Hogg was reported missing on March 12, 2002 after he did not turn up for work at a Burleigh bottle shop.

He was seen driving his 1992 red Toyota Celica coupe to his apartment at Teemangum Street in Currumbin Beach in the late afternoon of March 10, before speaking to his elderly mother on the phone at about 6pm.

The car, with Queensland registration plate 861 GBW, was last spotted between 1am and 3am, NSW time, in a car park near the Volunteer Marine Rescue Boat pontoon on the northern bank of Tweed River in Coral Street.

Witnesses reported seeing a number of people standing around the car, before a flash and loud bang, believed to be caused by the firing of a gun.

Police said Mr Hogg's body may have been thrown into the river, immediately adjacent to the Tweed River mouth's northern rock wall.

Days later, on March 14, Mr Rosson was shot and killed at his Pademelon Pass residence at Mount Nathan, north of the border.

Police said Mr Rosson was phoned by a man in the Coolangatta–Tweed Heads area about a 9mm CZ handgun he had listed for sale in the local Trading Post classifieds.

It is believed Mr Rosson was in the process of selling the handgun when he was shot.

Both the gun and ammunition were stolen, with witnesses reporting seeing two men in a red Celica visiting Mr Rosson at the time.

The car was found abandoned on 15th Avenue, Palm Beach, on March 20.

Police do not believe either Mr Hogg or Mr Rosson were known to each other, or involved in any criminal activity.
