Paul, I think I've found the answer myself. Look here at Jim Hargroves post about the Bolton Ford incident:

Deslatte could not describe the two visitors, but his colleague Sewell could. This is how he describes the Latino:
"Kind of heavy-set ..... not overly, but well built ..... he was curly haired ..... he had a scar over his left eye ..... olive complexioned and seemed to be educated ..... he had a Cuban accent and looked like a Cuban."
I think that description might fit David Morales.
