Rodolfo Hoyos Jr.'s character is referred to as "Captain Gonzales" by Dan Mathews, but is listed as "Sgt. Gonzales" in the end credits.
When Dan Mathews and Sgt. Ken Williams drive up and meet Sgt. Gonzales the three of them get in Gonzales' unmarked car and drive away, leaving the Highway Patrol car unattended with the windows down.
