I suspect that the self-tapping screw was used with a slide hammer, since the head had been broken off.

And since the slide hammer was gone, but not the socket wrench and a keyring with house keys and one GM key they probably tried first, I suspect mood enhancing substances at play.

Has anyone R&Red the ignition switch? DuckDuckGo finds results that suggests it's in there with bolts that shear off the head so they can't be removed.

I'l know more once I find a tow truck company that answers their phone.
