MARION COUNTY, Fla. — A Florida man remains held without bond as judicial proceedings advance in the violent death of a British woman who flew to the United States after spending two years discussing extreme sexual violence, abuse, and murder on an online fetish platform. Law enforcement authorities charged 54-year-old Dwain Hall with first-degree premeditated murder and kidnapping following the discovery of 31-year-old Sonia Exelby's body buried in a wooded area in Marion Oaks, Central Florida. Exelby, a music tutor from Southsea, England, landed at Gainesville Regional Airport in October 2025 to meet Hall, whom she had communicated with under an online alias.
According to court filings from the Florida Department of Law Enforcement (FDLE), Exelby originally agreed to pay Hall $4,000 to enact a dangerous arrangement that involved torture and murder. However, electronic messages recovered by forensic investigators indicate that after arriving at a rental property in Central Florida, Exelby experienced intense regret, expressed overwhelming fear, and repeatedly tried to withdraw from the agreement. Despite her efforts to end the ordeal, prosecutors allege Hall confined her against her will, subjected her to severe physical violence, and fatally stabbed her four times before burying her remains in a shallow pit.
Paper Trail and Digital Evidence Disprove Suspect's Initial Claims
When UK authorities initially raised concerns regarding Exelby's sudden international travel, law enforcement officers tracked financial transactions that tied Hall's roadside assistance business to attempted credit card charges on her account. During initial questioning by state detectives, Hall claimed he had never met the British citizen in person, alleging that she had merely contacted his towing service and that he declined assistance when her payment failed.
However, investigators quickly dismantled Hall's story through store surveillance video and store receipts. Surveillance footage recorded at a local Walmart showed Hall purchasing a shovel, rope, and gun cleaner shortly before driving to the airport to collect Exelby on October 10. Additional searches of Hall's mobile devices yielded disturbing videos depicting Exelby in an injured, restrained state, along with location data mapping his movements to the rural burial site.
Faced with the evidence, Hall altered his statement, acknowledging that he had maintained a two-year online dialogue with Exelby centered on bondage and severe harm, while maintaining that he was attempting to act as a mentor for her mental health struggles.
Local police in the United Kingdom collaborated closely with American federal and state agencies once Exelby's family reported her missing from her home.
"We received a report on Sunday October 12 that Sonia was missing from her home in Southsea," a spokesperson for Hampshire Police stated during the joint missing persons investigation. "Initial inquiries established that she had travelled outside of the UK prior to the report being received."
U.K. authorities continued supporting foreign law enforcement as state forensic teams examined digital artifacts and physical evidence recovered from the Airbnb rental and surrounding property.
"The constabulary was continuing to support the FDLE investigation, while specially trained officers were providing assistance to Ms Exelby's family in the UK," the Hampshire Police spokesperson added.
Victim's Messages Reveal Fear and Confinement Before Death
Exelby’s tragic final hours were preserved through messages she sent to a friend using an online gaming application while trapped at the Florida rental property. In those communications, she described her terror as Hall's actions escalated far beyond what she had envisioned, explaining that she felt powerless to escape.
In one text message reviewed by FDLE agents, Exelby wrote: "I thought he'd do it quick and not give my mind time to stew." Shortly before her communications ceased, she sent another message expressing her panic, writing: "I'm so scared I'm so broken and in so much pain..."
Court documents note that Hall restricted Exelby's movements and warned her that she would not be permitted to leave the premises alive. Investigators emphasized that these text exchanges demonstrated how Hall exerted total control over the vulnerable victim while ignoring her explicit pleas for release.
The case has drawn widespread attention from criminal justice experts and mental health advocates, who point to the incident as a stark warning about how online platforms can be exploited by predatory individuals targeting psychologically vulnerable people.
"Hall was controlling her," Florida Department of Law Enforcement investigators noted in court documentation detailing the coercive environment and digital trail leading to the suspect's arrest.
