Don't bring a firearm with you, what you might find out while looking for your daughter, could make you lose it and take your anger out on a POS that has sway over her. As much as I agree with adding another vent hole or three to him, that's something for another time.

Get your daughter and get her home so that she can get off whatever she's on and away from someone that might be keeping her in that condition. Hopefully you can find a couple guys that live in the area that can help you out, show you where to look...

Just be careful and don't venture into any areas that you know aren't safe unless you have backup. Or call the cops and have them go in and do a welfare check.
