Benita Breen -- Pills or Heart?

The 25-year-old vocalist (real name Mary Louise Breen) had been a featured singer with various "name" bands like Ted Weems, Henry King, and Bob Strong.  On November 13, 1945, Breen's body was found in bed by her mother in their home at 915 Margate Terrace in Chicago.  Police located an empty bottle of sleeping pills in the bathroom.  While a coroner's jury was unable to determine whether the death was accidental or suicide, Breen had been treated for a nervous disorder five month prior to her death.  Her father insisted that Breen had instead suffered from a heart condition.
