Torres is the Quartermaster of the Brotherhood of Steel armory in the Hidden Valley bunker

On finding the missing laser pistol for Knight Torres.

Talk to the Brotherhood Quartermaster again after you agree to look for the pistol. She will suggest talking to the firing range officer (has no name, will tell you you can use the firing range) about who last had the laser pistol. He will say that Initiate Stanton was the last person to check it out but he turned it back in. Talk to Initiate Stanton and confront him. He will confess and tell you about Scorpion Gulch and where he lost it by a body.

you may have trouble finding the missing Laser Pistol. It can be found on top of the rocks at the center of the lowest point in Scorpion Gulch. There's a dead body on the ground before the rocks; walk directly past it and the pistol is atop a collection of rocks.

you have to first get the tip that the laser pistol is in Scorpion Gulch. Before that time it is not there.
