The reason the one is in jail is because of assault and battery... Or is it assault? Always get that part mixed up. Either way she's in jail because of that. Still doesn't show if the "squatter" part is bs. Both can be true. The one is an asshole for throwing a tarantula and the other could be a squatter. We don't know about the Squatting because of the lack of information.
I'll stick with my original statement, lazy reporting
