Due to technological evidence and investigative genetic genealogy, the likelihood of future serial killers operating undetected for extended periods is 'next to nil.' Even crimes involving distance, like the DC snipers, or those where victims don't have direct contact, can be solved through DNA on casings or other trace evidence. Cases like the Zodiac Killer, unsolved for decades, are unlikely to occur again.
