Although Albert DeSalvo was widely thought to be the Boston Strangler, police and others analysing the case have long doubted the truth of his confession. Sentenced to life for a series of rapes, he was murdered in prison. DeSalvo’s body was exhumed for DNA testing, and compared to a substance found on the exhumed body of the Boston Strangler’s last victim. In 2001, it was declared not to match, but in 2013 officials announced that improvements in DNA extraction technology produced viable samples from the degraded evidence. DeSalvo’s body was reexhumed and found to match.
