He told his mother he knew something about someone important. Two weeks later, he vanished.
Steven Williams, 38, disappeared on June 14, 2005, after being dropped off at a trucking company in Gillman, in northwest Adelaide, South Australia. Twenty years later, his body has never been found — but his daughter says she believes she finally knows what happened to him.
Who Steven Williams Was
Williams was the former president of the Gypsy Jokers Motorcycle Club, having stepped down from the role roughly 14 months before he vanished, reportedly to spend more time with his young daughter, Blayze. He worked as a debt collector and had, according to police, begun writing a book about his life and activities within the outlaw motorcycle gang world — something that reportedly hadn't sat well with some in that community.
The Day He Vanished
On June 14, 2005, Williams spent time with his mother, Janice Hutchin, at her home, as he often did. She later said he seemed distracted that day. He received a phone call, telling her he needed to head to the Gepps Cross Hotel. That afternoon, he was dropped off at a trucking company in Gillman owned by a senior member of the Finks motorcycle club, believed to be collecting a debt on someone's behalf. He was never seen again. His white Ford Falcon was later found abandoned in the Gepps Cross Hotel car park.
He was reported missing two days later by his girlfriend.
What Investigators Believe Happened
Police believe Williams was killed shortly after arriving at the Gillman property. Investigators believe his body may have been removed from the site in the back of a white utility vehicle, covered by a tarpaulin, seen parked on a nearby street later that same day. Despite extensive searches of the industrial area around Gillman, as well as further searches at Port Gawler and Middle Beach, no trace of him has ever been found.
Competing Theories
Police have never established a definitive motive. Detective Sergeant Paul Ward told The Advertiser that Williams's book project had reportedly caused friction within outlaw motorcycle gang circles, and that his disappearance could equally have stemmed from something as straightforward as a debt collection gone wrong.
His mother, Janice, has publicly floated a different theory: that Williams had learned something damaging about a prominent figure in South Australia, possibly connected to police or politics, and was planning to go public with it. She's said she doesn't believe bikies acted on their own initiative, suggesting that if they were involved at all, someone else would have had to hire them. In the years following his disappearance, unverified rumors have circulated about how his body may have been disposed of, none of which have ever been confirmed.
A Daughter's New Claim
In June 2025, on the 20th anniversary of her father's disappearance, Blayze Williams gave an exclusive interview to 7NEWS stating she believes she now knows who killed her father and where his remains are located. Details of her claim have not been made fully public, and as of the most recent reporting, no arrests have resulted from it.
Where the Case Stands Now
The case remains formally unsolved. Police have said that while many potential witnesses within the bikie community have declined to cooperate over the years, information has continued to trickle in through Crime Stoppers. A reward of up to $200,000 remains on offer for information leading to a conviction and/or the recovery of Williams's remains.
