Between 1962 and 1964, the Boston area was terrorized by the "Boston Strangler," who assaulted and strangled 13 women, ages 19 to 85, in their homes.
The killer often gained entry by posing as a repairman or using charm to exploit the victims' trust.
Albert DeSalvo later confessed to the murders, providing detailed accounts, though inconsistencies and a lack of physical evidence left doubts about his guilt.
In 2013, DNA testing finally linked DeSalvo to Mary Sullivan, the Strangler’s last known victim.
