The Boston Strangler (1968)

boston 1962: a woman is cruelly murdered. the case would be forgotten if, shortly afterwards, there were no homicides with too many similarities to be purely casual. boston police and federal agents understand they are facing a maniac. but the array of forces does not intimidate the murderer who strikes again, between 1962 and 1964, for twelve times. federal agent john bottomley has followed the case from the beginning and with great patience and intuition he puts himself on the right track. the suspect is albert desalvo, a worker and a normal family man.
