With the wealth of tools that modern homicide investigators have at their disposal, it has become mighty hard to get away with murder. Even disregarding the fact that the world is much more heavily monitored and densely connected than ever before, the practice of using DNA technology to identify parties involved with a crime has been continually refined, ever since it was first used in criminal cases in the early '90s. These days, a suspected murderer need not even necessarily be identified by their own DNA — familial, or "genealogy" DNA, is just as effective a tool in some cases, and the use of DNA evidence combined with classic investigative techniques to solve cases is proving to have a wider reach on a year-by-year basis. This tech is so effective that its retroactive application is putting more and more murderers of years past, long before its use came into vogue, in the crosshairs of law enforcement. And even without DNA evidence, fresh case-breaking leads can materialize decades later; sometimes the criminals flash their cards, perhaps by bragging over drinks in a pub, or confiding to a friend. Virtually every state, county, and province in North America has a backlog of active cold case investigations, but those backlogs are starting to get a little thinner, due to two factors: the inevitable march of technology, and the fact that homicide investigators never, ever give up.
