TAMPA, Fla. (WFLA) — A Florida man is charged with murdering a woman who is believed to have traveled from the United Kingdom to be killed.

The Florida Department of Law Enforcement began investigating the incident on October 13 after it was contacted by INTERPOL regarding a missing woman sought by UK authorities, according to an arrest report filed in Marion County court.

Sonia Exelby, 32, was reported missing from her home in Portsmouth, England. She flew from London to the U.S., arriving at Gainesville Regional Airport on October 10, and was supposed to return on the 13th, but did not make it on her flight.

UK authorities described her as having mental health diagnoses and said she had expressed suicidal ideation in the past. Evidence on her computer suggested she was suicidal again and would travel abroad “to be possibly sexually abused, tortured, and murdered by unknown individuals living in the United States.”

On October 11, a roadside assistance service attempted to charge her debit card several times in varying amounts, and a $1,200 transaction eventually went through. FDLE contacted the business owner, Dwain Hall, 53, who said the card belonged to a customer, but “could not produce any information about the woman’s car, location, nor cellphone records to support his assertion that he received a call from someone during the time he said he received the call and charged Exelby’s credit cards,” the arrest report said.

That same day, Exelby tried to contact a friend through Discord, an online messaging and video chat service. Detectives described the message as “long and at times disjointed.”

“I’m sorry he keeps taking my phone he doesn’t trust me with it,” She wrote, in part. “He made it clear there was no way out unless I shoot him.”

“I’m sorry I don’t even know what I’m saying and I’m trying to be quick and My times up,” Exelby wrote.

Police said evidence places Hall at the airport and later at Exelby’s Airbnb in the small town of Reddick, which is located between Gainesville and Ocala. Hall, who is married, told detectives that the pair originally met on a fetish website and had “rough sex” at the Airbnb.

The arrest report said Hall admitted to taking a video of Exelby, but deleted it. Detectives recovered the video, reporting that Exelby appears disheveled, with bruises and abrasions on her face, neck and chest.

In the video, Hall asks Exelby to tell him why she is here. She responds, “Because I’m awful person.” Detectives said Hall instructed Exelby to verbally degrade herself during the video and she was hesitant to respond to him.

“This is how you wanted to die, right? You wanted to be beaten and made to suffer because you’re such a piece of s***,” Hall said in the video, according to the arrest report. Police said he made Exelby repeat the statement.

Hall’s cellphone data placed him in a wooded area in Marion County where Exelby’s body was later found in a shallow grave. An autopsy conducted on October 18 indicated Exelby died from four sharp force injuries, likely caused by a knife, and the manner of death was homicide. DNA evidence also pointed to Hall, the arrest report said.

Hall was believed to have sent the murder weapon, a knife with custom engraving, to a friend in Ohio, warning him “there might be a big storm coming for me,” the arrest report said. Police said Exelby’s blood was found on the knife.

A source contacted FDLE and said they believed that “Hall killed someone and the victim of the homicide was a woman in her thirties from the UK. Hall told him he helped her die because she couldn’t do it herself.”

Hall was charged with first-degree murder, kidnapping, credit card fraud and unlawful use of a communication device.
