|Albert DeSalvo says he murdered 13 women in the Boston area
1967: 'Boston Strangler' sentenced to life
The The man who claims to be the 'Boston Strangler' has been jailed for life after being found guilty of assault and armed robbery against four women in Connecticut.
Albert DeSalvo says he murdered 13 single women in the Boston area between June 1962 and January 1964, creating a climate of fear in the city.
The women, aged between 19 and 85, were sexually assaulted and thenstrangledto death in their homes.
Some were found with trademark ribbons around their necks.
But the 35-year-old has not been charged with any of the murders because of a lack of evidence.
During the seven-day trial, DeSalvo's lawyer, F. Lee Bailey, attempted to prove that his client was guilty of the murders, and should be found insane and sent to a psychiatric hospital for life.
Mr Bailey described DeSalvo as "uncontrollable" and sending him to prison would be a cruel punishment.
He said: "There were 13 acts of homicide by a completely homicidal vegetable walking in the form of a human being."
But the jury found DeSalvo legally sane and not guilty of the murders.
The judge said: "This defendant must be incarcerated for as long as he shall live or until psychiatric science can cure him."
The former military police officer has been held on charges of rape in the Bridgewater State Hospital in Massachusetts since 1964.
He will be kept there pending an appeal against his conviction.
Mr Bailey has said that shortly after DeSalvo arrived at the hospital, which has a designated section for patients with criminal records, he told other inmates that he murdered the women.
DeSalvo has said: "I would go home and watch what I had done on TV. Then I would cry like a baby."
Because DeSalvo's police record was filed under "breaking and entering", he never came under suspicion during the murder hunt.
Detectives, pathologists and psychologists were investigating known sex offenders.
Some women in Boston were so terrified by the murders that they carried pepper, ammonia and tear-gas bombs to protect themselves.
