A leading expert on Bristol's waterways has definitively stated that missing student Jack O'Sullivan could not have fallen into the water. Mike Ferguson, a former deputy harbourmaster with decades of experience, told the BBC there was "no chance whatsoever" that Jack, who disappeared on 2 March 2024, entered the River Avon and subsequently remained unfound. This assertion directly challenges the initial assumptions made by police and the public in the early stages of the investigation.
Jack O'Sullivan, then 22, was last seen in the early hours of 2 March 2024 after attending a house party in the Hotwells area of Bristol. CCTV footage captured him attempting to stop taxis without success, with his last likely sighting at 03:38 GMT on Bennett Way slip road, heading towards the city centre. In the immediate aftermath of his disappearance, a prevalent theory, including among police, was that Jack had accidentally fallen into the river. However, as time elapsed without any trace of him, this assumption began to be questioned.
Mr. Ferguson, who served eight years as deputy harbourmaster and possesses extensive knowledge of the river's currents, tides, and recovery procedures, explained that any body entering the River Avon would almost certainly be caught in one of seven well-known "catchment points" between Avonmouth and Hanham. He stressed that, based on his experience and records, no body has ever been swept out to sea without being recovered at these specific locations. He has dedicated hundreds of hours over the past two years to producing independent reports on the case, exploring various scenarios.
Avon and Somerset Police confirmed they have kept an open mind throughout the investigation, stating that "Jack entering the water is among the scenarios we have considered." The force also noted that information from third parties, including independent reports from nationally-accredited experts, has been reviewed and incorporated into their enquiries. Despite these considerations, the police have not publicly altered their stance on the potential for a river fall.
Jack's mother, Catherine O'Sullivan, expressed that the former harbourmaster's report has provided her family with a renewed sense of focus. She believes the narrative surrounding the harbour was established too early by the police. "When you have a piece of information that categorically tells you that's not possible, then that's really important for people to understand," she said, adding that if Jack were found anywhere other than in the water, it would raise many new questions. The family remains committed to finding Jack, with Catherine stating, "My life is completely on hold."
