Betty Tyson, who spent half her life in prison for the brutal murder of a businessman in a gloomy alleyway in Rochester, N.Y., before a judge ruled that she had been wrongfully convicted, died on Thursday in Rochester. She was 75. Her sister, Delorise Thomas, said the death, in a hospital, was caused by a heart attack. On May 28, 1998, 25 years to the day after she was arrested, Ms. Tyson, 49, left the maximum-security Bedford Hills Correctional Facility in Westchester County and headed home to freedom after Monroe County’s district attorney announced that he would not seek to try her again. By then she had become New York State’s longest-serving female inmate.
