It’s been 20 years since notorious bikie boss Steve Williams vanished without a trace.

He was last seen on June 14, 2005, at about 2.30pm at the Gepps Cross Hotel in Adelaide.

Police believe he was then dropped at a trucking company in Gillman by an associate.

His body has never been found and, while bikies, his family and the police all have differing theories on what happened to the Gypsy Joker, all agree he was likely murdered.

A $200,000 reward is still on offer for information leading to a conviction or the recovery of Mr Williams’ remains.

Now, investigative reporter Luke Williams (no relation) revisits the case and uncovers secrets of the missing Joker in this three-part subscriber exclusive documentary launching Friday.

Major Crime detectives believe the case is solvable – and that there are people who know exactly what happened to the notorious bikie.

Detective Sergeant Paul Ward, Major Crime Investigation Branch, said “despite the code of silence in outlaw motorcycle gangs” the police had “received information and tip offs on potential burial sites” over the years.

“Over the last 20 years, friendships and loyalties may have changed,” he said in a statement marking the anniversary of Williams’ disappearance.

“People are 20 years older, they may now have children of their own. I ask them to put themselves in Blayze Williams’ position, growing up not knowing what happened to her father.

“For the sake of the Steven Williams’ family, if you have information, please contact Crime Stoppers and help find his remains and bring him home to his family.”
