It’s in the garage so it’s not insulated. This some friends of ours daughters house. Her workout station is right there. Had she been working out, the bullet would have gone right over her head. We looked around and can’t find the bullet. It didn’t make it to the other side of the garage. I think it came from a distance, maybe I35 and could be in the wall.Top pic is the inside drywall? Can you see any insulation fibers poking through?
