John Ayres

An unidentified man picks up a hitchhiker, a migrant worker, kills him with a tire iron, plants false identification on his body, and then wrecks the car to make the hitchhiker's death appear to be accidental. Doctor's report to Highway patrol indicates murder. Mathews, in checking, finds five similar "accidents". Dan suspects an insurance pay-off racket.

Posing as Hardie, an outlaw with a sense of irony robs the Wells Fargo office.

A fugitive hides in a concrete cube for seven years so he can not be prosecuted for his crimes.
