British Woman Flew to the US to Meet a Man She Met Online, Then Allegedly Agreed to Pay Him $4,000 to Carry Out Her Dark Fantasy

Court records claim that British woman Sonia Exelby tried to pull out of a disturbing arrangement before she was killed, and prosecutors now believe her final messages could become some of the strongest evidence when the case goes to trial.

Dwain Hall, 54, from Ocala, Florida, has been charged with the murder of the 31-year-old British woman after investigators said she travelled from England to the United States in October 2025 to meet him. Prosecutors allege the meeting was linked to an online fantasy that turned into a real-life killing after Sonia changed her mind and no longer wanted to go through with it.

Hall has been charged with first-degree premeditated murder and kidnapping. He has pleaded not guilty to all charges, and his trial is expected to begin on 5 November. As with every criminal case, he is presumed innocent unless proven guilty in court.

The case has attracted attention around the world because it involves online fetish communities, private messages, videos, financial records and claims that Sonia withdrew her consent before she died. Prosecutors say the case is no longer about an agreement between two adults but about what happened after Sonia made it clear she no longer wanted the plan to continue.

Investigators said Hall and Sonia first met online in 2023 through a fetish website. According to court documents, they spent almost two years talking online. Their conversations reportedly focused on bondage, domination, suicide and Sonia’s claims that she had fantasies about being killed. Prosecutors said Hall described himself as Sonia’s “mentor” as their online relationship became closer and more detailed.

Court records claim the two eventually agreed that Sonia would travel from England to Florida, where Hall would carry out what investigators described as her wish to be sexually abused, tortured and killed. Prosecutors also allege Sonia agreed to pay Hall 4,000 US dollars to help settle one of his tax debts. Investigators claim they even discussed how her disappearance could be explained to family members and what they would tell police if questions were ever asked.

Authorities also revealed that British officials had reportedly stopped Sonia from travelling under similar circumstances in 2024. Court records further state that investigators were aware she had documented mental health conditions, although prosecutors have not claimed those conditions alone explain what happened.

According to investigators, Sonia flew from Portsmouth to Gainesville Regional Airport on 10 October 2025. They allege Hall picked her up at the airport and drove her to an Airbnb property in Reddick, Florida, which Sonia had rented for the visit.

Before collecting her, surveillance cameras and shop receipts allegedly showed Hall buying several items, including rope, parachute cord, gun cleaner and deodorant. Prosecutors also claim he later returned to the same shop to buy a shovel in a separate purchase. Investigators believe these purchases show that Hall had carefully planned what would happen before Sonia even arrived in Florida.

However, prosecutors say the most important evidence comes from messages Sonia allegedly sent less than a day after arriving in the United States.

Court records state that Sonia contacted a friend through Discord and described a situation that was very different from what had been discussed online. She reportedly wrote that “last night was so bad” and claimed Hall had taken away her phone and locked her inside the Airbnb because “he doesn’t trust me with it.”

She also reportedly told her friend that she believed everything would happen quickly but instead realised she had time to think about what was happening. In another message, she allegedly wrote that she was extremely frightened, saying she was “so so scared,” felt broken, was in pain and could only lie still. She also reportedly wrote that she was trying to be quick because her time was running out.

Prosecutors believe these messages clearly show Sonia no longer wanted the plan to continue and had withdrawn her consent before she was killed. They are expected to use these messages as a major part of their case during the trial.

Investigators also recovered what they described as a deleted four-minute video that they allege Hall recorded inside the Airbnb.

According to the arrest affidavit, the video shows Sonia with visible bruises while Hall questioned her. Investigators said she appeared frightened, rarely looked directly at the camera and followed Hall’s instructions throughout the recording. Court documents claim Hall told her to repeat degrading statements before responding by saying, “Good, good.”

Financial records have also become part of the prosecution’s evidence.

Investigators claim Hall used Sonia’s debit card seven times through his roadside assistance business on 11 October after discovering she had not brought the cash payment they had discussed. Court records say Hall later admitted becoming frustrated because only around 1,200 US dollars could be processed after several card payments were declined.

When Sonia failed to board her scheduled flight back to the United Kingdom on 13 October, her family became worried and reported her missing. Four days later, investigators discovered her body buried in a shallow grave in a wooded area of Marion County, Florida.

According to court records, Sonia had suffered four stab wounds. Investigators also recovered a product label in the soil covering the grave that allegedly matched the shovel Hall had purchased before her arrival.

Deputies later stopped Hall on Interstate 75 near Ocala. Before his arrest, prosecutors allege he sent a Facebook message asking a friend to keep a package containing what he described as “precious and valuable personal items.”

When investigators recovered the package, they reportedly found a bracelet and a seven-inch knife. Court records state that DNA found on blood on the knife matched Sonia’s DNA.

Investigators also claim Hall first denied knowing Sonia when questioned but later admitted that he had recorded a video of her before deleting it.

Prosecutors argue that the digital evidence, surveillance footage, financial records, DNA evidence and Sonia’s final messages all point to the same conclusion. They claim that although Sonia initially travelled to Florida as part of an agreed arrangement, she later changed her mind and tried to stop everything before she was killed.

Hall strongly denies the allegations against him and has pleaded not guilty. The evidence will be examined in court, where prosecutors must prove their case beyond reasonable doubt. A jury in Marion County is expected to hear the trial when proceedings begin in November.
