Sept. 3, 1962: Boston Police detectives worked through the night, trying to solve the Strangler case after 67-year-old Jane Sullivan was discovered on Aug. 30, 1962, throttled to death in her apartment. She was believed to tbe the sixth victim of the Strangler. On this night, news stories reported police were searching for a 56-year old Brookline man who had been arrested more than once for trying to choke women. This suspect had a history of mental illness, and had worked as a practical nurse in at least seven hospitals in the city, getting the jobs through false documentation. A common thread with five victims was that they had some connection with hospitals or medical clinics. Jane Sullivan had worked as a night-shift nurse at Longwood Hospital.
