I wonder if Jenny were really killed in Wisconsin or if he chose to say Wisconsin because there's no capital punishment.
So far there's been no mention of why Jenny would be in Wisconsin.
He drove to Michigan to meet his ex in a hotel.
He drove to Minnesota to meet Laura in a hotel.
He drove to ??? to meet Jenny in a hotel.
If he drove to Oregon, California or even Washington State, they all have the death penalty, so I think he'd lie through his teeth to put her death happening elsewhere. Also, I wonder if that would have to do with his lack of memory as to what -YEAR- Jenny died.
