A decades-old killing may have been solved with new forensic tech and DNA from a conch shell

Most recently in Massachusetts, the technology led Bristol County prosecutors to the arrest of Ivan Keith in connection to at least four unsolved rapes in the 1990s. Keith had evaded the authorities for more than 20 years, and was arrested in Maine, where he was living under a false name, prosecutors said. He has since been convicted in those rapes and is serving a 50-year state prison sentence, prosecutors said.
