Default VS980 Burnt to a Crisp?

My brother claims his G2 was acting up yesterday. On his way to work in the afternoon, he claimed it got really hot in his pocket. Anyway now it won't turn on, the screen stays black. Putting it on the charger doesn't seem to have helped. Computer doesn't see it when I plug it in via USB.

He is completely stock, not even rooted. I don't think anyone is going to be able to help here, but I'm curious if anyone else has had a similar issue? I guess he didn't know he could kill it by holding the power button down for so long, and probably just let it burn up in his pocket.
