BOSTON -- Massachusetts law enforcement officials say advances in DNA technology have led to a breakthrough in the last of the 1960s slayings attributed to the Boston Strangler.
Authorities are planning a Thursday morning news conference to discuss a "major development" in the nearly 50-year-old slaying of Mary Sullivan.
The 19-year-old was found strangled in her Boston apartment in January 1964. She was the last of about a dozen women whose deaths were attributed to the Boston Strangler.
Albert DeSalvo confessed to the killings but was never convicted. He was sentenced to life in prison on other charges and was stabbed to death there in 1973.
City police say in a statement "the miracle of science and DNA evidence" point to a suspect.
Sullivan is the only victim for which DNA evidence is available.
