Police have shared a man's apparent 'shopping list' that he made before allegedly murdering a British woman.

Sonia Exelby, a 32-year-old woman from Portsmouth, UK, traveled to America with the intention of being sexually abused and murdered, according to police.

Exelby was reportedly suicidal and wanted someone to kill her in a violent manner.

Dwain Hall has since been arrested in connection to her murder. In his arrest affidavit obtained by PEOPLE it detailed that Exelby was 'suicidal and traveling to the United States to be sexually abused, tortured, and possibly murdered'.

British police also found evidence of a suicide letter where she anticipated being 'mutilated and disabled for the rest of my life'.

It's believed that Exelby and Hall, from Ocala, Florida, started chatting online two years ago and met on a fetish website.

Exelby flew to the States in October and concerns about her whereabouts were later raised when she failed to board her flight back to the UK on October 13.

A few days later her body was found in Marion Oaks, Florida, with four stab wounds.

On the day she arrived in America, police say Hall purchased paracord, gun cleaner, rope and deodorant at a supermarket. CCTV shows him going back into the store for a second time shortly after to buy a shovel, the Mirror reports.

Florida Department of Law Enforcement (FDLE) announced Hall's arrest on November 17. It said in a statement: "The Florida Department of Law Enforcement (FDLE) arrested Dwain Hall, 53, of Ocala, on charges of first-degree murder and kidnapping in the homicide of a missing woman from the United Kingdom.

"The arrest follows a swift and intensive investigation that led to the discovery of her remains in Marion County less than one week after she was reported missing."

The murder charge came after Hall had already been charged with fraudulent use of credit cards and unlawful use of a two-way communication device in connection to Exelby's disappearance.

Hall allegedly made several attempts to use Exelby's cards and eventually managed to withdraw $1,200 in cash.

The 53-year-old has pleaded not guilty to all four charges he's facing.
