Where is Jeffrey Epstein's island — and what reportedly happened on Little St. James?

Court documents unsealed on Wednesday revealed dozens of people with a wide variety of connections to Jeffrey Epstein, a convicted sex offender. The names in the documents include accusers of Epstein, staff members and business associates, many of whom gave depositions about Epstein, who over many years allegedly exploited underage girls for sex at his homes in Manhattan; Palm Beach, Florida; and his private island near St. Thomas. Being named in the court documents is not an indication of wrongdoing.
