The hunt for the Zodiac Killer has never truly stopped. Over the years, various law enforcement agencies and dedicated individuals have continued to investigate the case, hoping to finally unmask the killer.

One of the more recent developments in the case came in 2018 when the Vallejo Police Department announced that they had used DNA evidence to create a composite sketch of the killer. This sketch, which was based on DNA found at one of the crime scenes, provided a new tool for investigators. However, it did not lead to the identification of a suspect.

Advances in forensic technology have given investigators renewed hope in recent years. DNA evidence collected from crime scenes has been reexamined, and genetic genealogy techniques have been used to identify suspects in other cold cases. There is ongoing speculation that similar techniques could eventually lead to a breakthrough in the Zodiac Killer case.
