We don't know. Probably another bounty hunter, or just some unlucky putz. Make up your own answer! Of course, everybody says it's Armstrong Houston from the Super Metroid comics published in Nintendo Power magazine, but as much as I'd like that to be the case, I have to say no. The game came out before the comics did, so if anything, the Houston character may have been based on the dead guy. But the dude in the game has no intended identity.
