[Ruy Dias de Bivar]

The REAL mad Trapper (Albert Johnson, not his real name) did not survive and there is a photo of him.

Three fictional movies were made about him, A British docudrama;

One awful one aimed at kids, staring Mike Mazurki; shown over two weeks on TV;

And a good one with Lee Marvin and Charles Bronson. DEATH HUNT.

Both fictional movies show the trapper surviving.

I first heard about it in a story in either TRUE or ARGOSY magazine back in the late 1960s.
