THE SECOND PASS THEORY. Investigators examining the eastern paddock of Richard Wills’ Ouyen farm reportedly identified tyre impressions showing a second vehicle pass partially covering the first — a detail that may indicate someone returned to the same ground shortly after the initial movement.

This forensic observation has become one of the most discussed elements in the suspicious death of 65-year-old Victorian farmer Richard “Rick” Wills, whose body was found buried in a shallow grave on his own 1,600-acre property in early April 2026.

Richard Wills, a well-known and hardworking grandfather from the remote Mallee town of Ouyen in north-west Victoria, was last seen leaving his home on Easter Sunday, April 5, 2026, around 8 a.m. He headed out to work on the farm as usual. When he failed to return for lunch, his wife of 32 years, Donna Wills, grew concerned. His phone and ute (utility vehicle) were later located on the property, but there was no immediate sign of Rick.

Two days later, on Tuesday, April 7, police searching the farm discovered his body in a shallow grave in the eastern paddock. He had been fatally shot, and there was evidence his body had been dragged behind a vehicle before burial. Victoria Police described the killing as “vicious” and confirmed it was being treated as foul play. Detectives from the Missing Persons Squad appealed for public information, noting that the person responsible was likely known to Mr Wills.

The Eastern Paddock and the Tyre Evidence

The eastern paddock — where Mr Wills was known to conduct regular checks, often at around 2 p.m. daily — became the central focus of the investigation. Forensic teams examined the dusty, open ground for clues.

According to circulating reports and social media discussions drawing on police updates, investigators identified tyre impressions in the soil. One set appeared consistent with initial vehicle movement on the day of the incident. Overlapping or partially covering these were marks from what has been dubbed the “second pass” — a subsequent vehicle traversal that partially obscured the first set of tracks.

This detail raises pointed questions:

Did the perpetrator return to the scene shortly after the initial crime to complete the burial or stage the site?
Was a second vehicle involved, perhaps belonging to an accomplice or used to transport the body?
Or could the overlapping marks result from the same vehicle making multiple passes while dragging the body and digging the shallow grave?

In forensic tyre track analysis, overlapping impressions can reveal the sequence of events, direction of travel, and even approximate timing if soil conditions (such as moisture or dust disturbance) allow differentiation. A “second pass” that partially covers the first suggests the return occurred soon enough that the earlier tracks had not fully settled or been erased by wind or weather — common in the arid Mallee region.

Ouyen, located about 100 km south of Mildura and surrounded by vast wheat and sheep country, is a tight-knit farming community where vehicle movements on private land are often routine but noticeable to locals familiar with daily patterns. The dusty soil in the paddocks can preserve tracks well under certain conditions, making it a valuable — yet challenging — surface for forensic work.

Recent Sheep Thefts and Motive Speculation

The Wills family has publicly stated that sheep had been stolen from the property in the weeks leading up to the tragedy. While some online speculation linked the murder to a supposed “Merino Mafia” or organized livestock theft rings, the family has firmly rejected those theories, emphasizing that they do not believe Rick was targeted by any criminal network.

Police have not ruled out any possibilities but have indicated the killer likely knew the victim and the farm layout well enough to bury the body on-site without immediate detection. The remote nature of the property and the short timeframe (missing for roughly two days before discovery) add layers of complexity.

Detective Senior Sergeant Steve Trewavas noted the “vicious” nature of the killing and the evidence of dragging, suggesting a high level of anger or a need to move the body quickly. The shallow grave itself points to a hurried attempt to conceal the crime rather than a meticulously planned disposal.

The 14-Minute or Routine Check Gap

Some reports highlight Mr Wills’ strict daily routine of checking the eastern paddock around 2 p.m. The fact that he vanished during or around one of these routine movements has fueled discussion about whether the perpetrator knew his habits intimately.

Combined with the second pass theory, this timeline element suggests the crime may not have been a random encounter but something that unfolded with knowledge of the farm’s rhythms. Did someone wait for him in the paddock? Did they return later to “clean up” or ensure the scene appeared unremarkable?

Forensic tyre evidence, while powerful, is not always conclusive on its own. Matching treads to specific vehicles requires clear impressions, and environmental factors like wind-blown dust in Ouyen can degrade tracks quickly. Investigators are reportedly cross-referencing any recovered impressions with vehicles known to frequent the property or linked to persons of interest.

Community Impact and Ongoing Investigation

The murder has shocked the Ouyen and broader Mallee farming community, where trust and mutual reliance are central. A GoFundMe campaign was established to support the Wills family, reflecting the outpouring of local sympathy for Donna, their children, and grandchildren.

As of April 16, 2026, no arrests have been made. Police continue to appeal for anyone with information about movements on or near the Wills property on Easter Sunday or in the following days. They are particularly interested in any unusual vehicle activity or sightings that could corroborate or challenge the tyre track findings.

The second pass theory remains a compelling but unconfirmed piece of the puzzle. In forensic terms, it could help reconstruct the sequence: an initial confrontation or shooting, followed by dragging, burial, and a return visit — perhaps to check the grave, remove evidence, or retrieve something left behind.

For a farming family in one of Australia’s most isolated regions, the betrayal feels especially profound if the perpetrator was someone known to them. Rick Wills was remembered as a dedicated worker, family man, and “world’s best poppy” — a gentle grandfather whose life was violently cut short on the land he loved.

The dusty tyre marks in the eastern paddock may yet speak volumes. As forensic experts continue their analysis and the coronial process unfolds, the overlapping impressions stand as a silent witness: someone came once, and then came back.

Police urge anyone with information to contact Crime Stoppers on 1800 333 000 or submit details via the Victoria Police website. The investigation remains active, with detectives stressing that even small details about vehicles or routines could prove critical.

This case underscores the vulnerability — and the resilience — of rural Australia. In vast paddocks where routines feel eternal, one deviation and a set of returning tyre tracks may hold the key to justice.
