Suicide notes were found next to the body of a woman in Florida believed to Deborah Jeane Palfrey, otherwise known as "The D.C. Madam."
"Detectives are investigating an apparent suicide of a (white female) that appears to be in her early 50s," Tarpon Springs police said in a news release.
Suicide notes were found near the body in a small storage shed next to a mobile home, police said.
Palfrey, 52, was reportedly staying at the home of her mother, who owns the property where the body was found, police said.
The Pinellas County Medical Examiner's Office will determine the cause of death, police said.
The county sheriff's office and the FBI are participating in the investigation.
Palfrey was convicted last month in connection with a high-end prostitution ring catering to Washington's elite.
