EIGHTEEN YEARS AS A NUMBER
The phrase “nearly eighteen years” appears repeatedly in accounts of the List case, and it deserves a moment of examination as a number — as a measure of both what John List achieved and what that achievement cost.
Eighteen years is long enough for a child born at the time of the murders to have grown to adulthood before the case was resolved. Patricia, the sixteen-year-old who died in November 1971, would have been thirty-four in 1989. Freddie, thirteen when he died, would have been thirty-one. The life they should have been living for those eighteen years — the education, the relationships, the work, the experiences of young adulthood — was not lived.
Eighteen years is also long enough for memory to fade, for witnesses to move away or die, for physical evidence to deteriorate, for the people most deeply affected by a crime to age significantly. The drama coach who had known Patricia List was in his mid-fifties by the time of the arrest, having spent nearly two decades with whatever memory he carried of her. The community members who had known the family were older, had moved on to other chapters of their lives.
For the investigation, eighteen years was long enough for the original detectives who had worked the case to have retired or moved on. The case file was still there, but the institutional knowledge built around any specific investigation — the context, the contacts, the accumulated understanding of the specific facts — erodes with time. Cold cases are harder to work not just because leads go stale but because the people who originally worked them are often no longer available.
For John List himself, eighteen years was enough time to build an identity that was, for practical purposes, real. Robert Clark had a work history, a marriage, community ties, a church community. The eighteen years that made the investigation harder were the same eighteen years that made Robert Clark more plausible. The longer he went undiscovered, the more solid the fiction became.
The arrest in year eighteen interrupted that trajectory. Had it not happened — had the America’s Most Wanted segment not aired, or aired without generating a useful tip — the trajectory would have continued. Robert Clark might have died of old age, as Robert Clark, and the warrant for John Emil List might still be technically active against a man who was no longer alive to serve it.
Instead, the trajectory ended in June 1989. The trial came. The conviction came. The sentence came. And the eighteen years of successful evasion ended in eighteen years of prison, before List’s death from pneumonia at eighty-two.
