I have the unmarked side quest where I need to find a laser pistol in Scorpion Gulch. I have gotten tips where they say it's near a dead body, and I remember finding that body and looting it but I can't find the body again (possibly it vanished since I looted it completely?) Are there any tips on where to find this gun?

(PS. I would check the wiki if I had a chance to get on it, but I have no pc that is allowed on there.)
