The most common interpretation is that the bulk of the money went with Cooper—wherever Cooper went. If he died, the money was presumably destroyed or buried with him. If he survived, he either never spent it (an almost inconceivable level of discipline over more than fifty years) or spent it in ways that escaped detection.
The argument that the money’s absence proves Cooper survived is not supported by the evidence. The money’s absence proves nothing about survival or death. What it shows is that $194,200 in cash has not been recovered or detected in circulation, which is consistent with multiple scenarios.

## The Ingram Discovery in Context: What Changed and What Didn’t
When Brian Ingram found those three bundled packets of bills in February 1980, the FBI’s response was swift and methodical. The bills were brought in on Monday, February 11. Serial number comparisons confirmed the match to the Cooper ransom within a relatively short period. The FBI sent agents back to Tena Bar two days later, on February 13, and found additional fragments near the original site—more of the deteriorated bills, buried deeper in the sand.
At the time, the discovery was treated as a potential breakthrough. Here was physical evidence, confirmed and specific, that placed part of the ransom at a particular location on the Columbia River. The location was approximately ten miles northwest of Vancouver, Washington—in Clark County, on the Washington side of the river.
The Columbia River is a major waterway that drains a large portion of the Pacific Northwest. Its tributaries and the rivers that feed into it from the Washington and Oregon sides cover a vast area. The Lewis River, the Washougal River, and numerous smaller streams all flow into the Columbia in the general vicinity of southwestern Washington. If Cooper had landed near any of these rivers or their tributaries and the money had eventually entered the water, the Columbia River’s currents could theoretically have transported the bills downstream to a deposit point.
