On another note, draining a battery repeatedly will destroy it. Until the issue is figured out you should remove a battery cable when you park. Also put a trickle charger on the battery for at least a day or two after draining it.

Chassis/ground, same thing. Yes, a sensitive enough ammeter in series would show the amount of mystery drain. Most cars have a fuse at the starter, you could also disconnect that when you leave the car.
