Vivian Austin, an 87-year-old black woman, died Sunday, May 3, 1992, in the 1600 block of West 60th Street. Austin suffered a fatal heart attack at her home in Harvard Park. Friends said she had been distraught by the rioting. "This is considered a riot case because the stress from the riot was well documented and is a contributing factor in death from arteriosclerotic disease," the coroner's report says.
