A $250,000 reward has been announced to help solve the 2019 suspicious death of Jason Barry Guise.
Jason was last seen on Charlotte Street, Wynnum on April 21, 2019 when he visited a food truck before returning to his Wynnum address on Bride Street sometime after 8pm.
He was reported missing on May 2, 2019 by his roommate.
On the May 8, 2019 Jason's body was located in a pit within a sewage treatment plant at Wynnum.
The last known confirmed sighting of Jason was around 7.20pm on April 21, 2019 riding a bicycle past the Waterloo Hotel on Berrima Street Wynnum.
It has believed, through medical examinations, that Jason died shortly thereafter. Jason's disappearance has been subject to a thorough investigation and extensive inquiries.
Acting Detective Inspector Mark Mooney of the Bayside Criminal Investigation Branch called on the community to help police bring those responsible for Jason's death before the court and give his family answers.
"A $250,000 reward is now in place for information that may lead to the conviction of the person or persons responsible for Jason's disappearance.
"It is particularly important to highlight the significance of the matter of indemnity offered along with the $250,000 reward.
"Any person who was involved in the crime but did not commit the crime who comes forward and speaks with police, is eligible for this indemnity from prosecution. Please take the time to consider this offer carefully."
Police believe Jason died shortly after he disappeared and that there are people in the local community who know what happened.
"We encourage anyone who has information and for whatever reason has remained silent, to put that aside and come forward and speak with us, however insignificant they feel that information might be," Acting Detective Inspector Mooney said.
"Jason's disappearance was out of character. He was in regular contact with his family and he had upcoming plans in life he was looking forward to.
"The community expects these cowardly acts to be fully investigated and those offenders responsible to be brought to justice, no matter how long it takes.
"Jason's family and friends deserve to know what happened to their son, brother and friend and we urge anyone who may have any information in relation to this matter to come forward."
In addition to the increased reward, which remains at the Police Commissioner's discretion, an appropriate indemnity from prosecution will be recommended for any accomplice, not being the person who actually committed the crime, who first gives such information.
