The $5,800 in rotting cash found by a boy — and the hijacker who vanished with the rest

The money came apart in his hands.

Brian Ingram was eight years old in 1980, playing along the Columbia River near Vancouver, Washington, when he found a bundle of rotting cash half-buried in the sand.

The bills were $20s, crumbling, fused together by water and time.

His family called the FBI.

Agents checked the serial numbers against a list that had been distributed to banks nine years earlier — the ransom list from the November 1971 hijacking of Northwest Orient Flight 305.

The numbers matched.

The $5,800 was the only physical trace of the hijacker ever recovered, according to the FBI's investigation records.

It is not established how the bundle ended up in the river.

It is not established whether the man who jumped from the aft stairway that night survived the fall into the woods below.

What is documented is the split: the bundle was divided between Brian Ingram and the FBI, and Ingram later sold part of it at auction, per the case file.

The rest of the $200,000 — $194,200 in $20 bills, also recorded by serial number — has never surfaced.

No suspect was ever arrested, charged, or convicted.

The man who took the money was never named.

A boy held the only proof that the hijacker had been real, that the money had been real, that the jump had happened at all.

The rest of the story is what the river kept.

THE NOTE AND THE FLIGHT

The man bought his ticket under the name Dan Cooper.

One-way, Portland to Seattle, on the afternoon of November 24, 1971.

The press later misreported the name as D.B. Cooper, and the typo stuck.

Shortly after takeoff, he handed the flight attendant a note.

The note claimed he had a bomb.

He demanded $200,000 in cash, four parachutes, and a fuel truck waiting in Seattle.

The flight attendant was the first to alert the cockpit.

The plane landed in Seattle.

The money and the parachutes were delivered.

Cooper released the passengers and most of the crew.

Then he ordered the pilots toward Mexico City, at low altitude.

Somewhere over southwestern Washington, he opened the aft stairway.

He jumped into the night.

The plane landed safely in Reno, Nevada, with only the crew aboard.

The FBI recovered the hijack note from the seat.

They also found a clip-on tie he left behind.

It is not established whether the bomb in his briefcase was real.

No explosive device was ever found or proven to exist.

The crew described him as calm and polite.

A controlled hijacking, a clean exchange, a quiet exit.

Then a man fell into the dark over Washington state.

The plane came down without him.

The money came down without him, too.

He was never seen again.
