Man arrested over cold case murder of Gregory Armstrong

Homicide detectives have charged a man with the cold case murder of Queensland man Gregory Armstrong.

Armstrong was last seen alive in Maryborough on May 7, 1997, and was later reported missing by his landlord.

A 45-year-old man, formerly of Maryborough, was today charged with one count of murder.

He will appear in Bundaberg Magistrates' Court this morning.

Detective Senior Sergeant Chris Knight said police were still appealing for information and the $250,000 reward was still on offer.

"Detectives believe that there may be more people who possess information about the murder of Greg Armstrong," he said. 

"There may also be people who are more willing to provide further information following today’s arrest. 

"The door is never shut on new information and we still want people to contact police.

"I hope that today's arrest reinforces our strong belief that the passage of time is no comfort to people who commit violent crime."

The $250,000 rewards is on offer for information which leads to the conviction of the person or persons responsible for the murder.

The rewards also offers indemnity against prosecution for an accomplice, not being the person who actually committed the murder, who first gives the information.

Police renewed their call for information into Armstrong's murder in September 2018.

The Tuan Forest, north of the Sunshine Coast, was searched for a second time, involving 40 SES crews and the dog squad.
