(CNN)Former American swimming champion Jamie Cail has died in the US Virgin Islands, according to authorities who are investigating her death on the island of St. John.

US Virgin Islands Police Department says Cail's boyfriend, who was not identified, left a bar just after midnight to check on her last Tuesday when he found her on the floor of their home.
The boyfriend and a friend got her into a vehicle and transported her to Myrah Keating-Smith Community Health Center where CPR was rendered, authorities said.
    Cail, 42, ultimately "succumbed to her ailment," officials added, saying she had died on arrival. The Criminal Investigation Bureau is investigating, police said. A cause of death has not been released.
      Cail won gold at the 1997 Pan Pacific Championships as a member of the US women's 4x200-meter freestyle relay, according to FINA. She also won a silver medal in November 1998 at the FINA Swimming World Cup in Brazil in the women's 800-meter freestyle.
      "USA Swimming is saddened to hear of Jamie Cail's passing," said Lindsay Mintenko, managing director of the US national swimming team. "Jamie was a proud member of our National Teams in the late 1990s and was a cherished teammate. We extend our condolences to Jamie's friends and family."
      As a teenager, Cail spent some time at the Bolles School in Jacksonville, Florida, a private college-preparatory school known as a swimming and diving powerhouse.
        Former Bolles swimmer Jooyoung Lee said he "never met anyone who had a work ethic like Jamie."
        He said she would push herself to total exhaustion during training.
