DNA testing plus new forensic genealogy studysolves 1956 case
Detectives working cold cases have automatic advantages and disadvantages.
One disadvantage is obvious: a case often has gone stale, with disappearing tips and witnesses and few if any new leads. But an advantage is that there often is more time to track down possible witnesses and to review evidence to rebuild a case for a fresh start.
The widespread use of technology in crime-solving methods - such as DNA testing, new national crime databases, and growing internet platforms – provides new ammunition when looking at old cases, too.
Detectives in Montana used DNA and forensic genealogy to bring about one of the oldest cold case solutions known to date, according to a news story by National Public Radio. That case dates to 1956 when hikers found the bodies of a young couple. He had been tied and shot in the head from behind; she had been raped and then killed in a similar fashion.
A cold case detectives uncovered in the old files on the murder case a laboratory microscope glass slide that contained DNA material. Getting a familial match of a cousin and then following genealogical connections by moving backwards on a family tree, the detective and geneologist tracked down a man who had moved from Montanna to Missouri.
However, the man had died and his body had been cremated.
Again, genealogy was put to work. Family members agreed to testing, and the result proved the dead man had been the killer. Case solved.
