Details: Born in the Philippines in 1929, Teresita Basa was a respiratory therapist at Edgewater Hospital in Chicago, Illinois. She was quiet and unassuming, but in February 1977, the fire department was called to put out a fire in her home. In the blaze, they found her nude body under a burning mattress with a butcher knife buried in her chest. Suspects: The police pursued several leads, but they were all subsequently dismissed. Extra Notes: This case first aired on the April 25, 1990 episode. It was also covered in the book, Houses of Horror, by Richard Winer.
