In the summer of 1974, 85-year-old Opal Cooper was beaten to death in her Indianapolis home during a robbery. The violence alarmed the neighborhood and highlighted risks to elderly residents.

Howard Arthur Allen was arrested in connection with Cooper’s killing and charged. Prosecutors secured a conviction on a reduced count of manslaughter; Allen was sentenced to 2 to 21 years in prison. He was paroled in January 1985 and returned to Indianapolis.

The case record notes later criminal activity by Allen after his parole, but details of those events occurred after the parole date. Does anyone remember Opal Cooper, her neighborhood in 1974, or have information about the case that could shed light on what happened that summer?
