What can also be said is that he married in 1947 — two years after the war — and worked and raised a family for seventeen more years before leaving. Whatever the war had done to him, it had not immediately produced the departure. The departure happened in 1964, nearly two decades after the events off Okinawa.
The gap between the war’s end and the departure argues against a simple causal model. It does not prove that the war had no role — trauma can surface and resurface across long periods, and the relationship between wartime experience and long-term behavior is not a simple one. But it does establish that any connection between what Nichols experienced in the Pacific and what he did in 1964 is not a direct or immediate one, and that any such connection is interpretive rather than documented.
The investigators who worked the case did not, in their public statements, cite military service as an explanation for Nichols’s behavior. They treated his Navy background as biographical context and as a source of corroborating information — Phil’s confirmation of the service and injury aligned with what the genealogical evidence indicated — rather than as the key to the mystery.
The mystery, in the investigators’ framing, remained genuinely unresolved. Elliott’s statement that “there has to be a reason” was not an explanation. It was an acknowledgment that the behavior required a reason, followed by the honest admission that the reason was unknown.
