DNA: This Guy Was the Boston Strangler

DNA evidence appears to at least partially confirm what many had already suspected: that Alberto DeSalvo was the Boston Strangler. Authorities have already produced a "familial match" using DeSalvo's relatives, and are exhuming DeSalvo himself in hopes of directly linking him to the last of the Strangler's victims, Mary Sullivan. There doesn't seem to be any DNA evidence for the other 10 Strangler murders, authorities said.

While the familial match rules out 99.9% of other suspects, the AP reports that authorities can't close the case until they get a direct match. DeSalvo confessed to the Strangler killings, but was never convicted of them, and later recanted. He went to prison for life anyway on armed robbery and sexual assault charges, and was stabbed to death while behind bars. (More Albert DeSalvo stories.)
