Robert Bishop, who was 69 at the time of the attack, had been living at the Symphony at Aria long-term care facility since some point after the home invasion on May 8, 2007, on the 5100 block of South Calumet Avenue about 1:55 a.m. Bishop died of complications of traumatic brain injury from a remote assault, the medical examiner's office determined. Bishop died Monday, and his death was ruled a homicide on Saturday.
