This is the characteristic structure of a cold case that depends on a named suspect. When the suspect is known by name, investigators can locate and interview witnesses, run parallel financial investigations, subpoena records, and build the kind of evidentiary picture that supports a prosecution. When the suspect’s real identity is unknown, all of those tools are blocked. You cannot issue a warrant for a suspect who has no verified identity. You cannot trace financial records for someone you cannot name. You cannot locate witnesses through networks defined by a real person’s actual history.
Gerhartsreiter’s method — the layered aliases, the physical mobility, the willingness to leave — was not only about social deception. It was also, whether consciously or not, an effective way to make himself unprosecutable for as long as his real identity remained unknown.
The moment his real identity was established, in August 2008, the protection ended. The aliases didn’t collapse one by one. They collapsed all at once, when the fingerprints matched. Everything he had done under every name suddenly belonged to the same person, and that person was now identifiable.

## The Prosecution of Old Crimes: A Note on Time and Justice
The murder charge filed against Gerhartsreiter in March 2011 was based on events that had occurred twenty-six years earlier. This raises questions — both legal and practical — about what such a prosecution can achieve and what it costs.
From a legal standpoint, first-degree murder has no statute of limitations in California. The passage of time does not bar prosecution. The question is only whether the available evidence can support a conviction beyond a reasonable doubt — and whether prosecutors, exercising the discretion they have over charging decisions, believe the case is worth bringing.
