I think the State's case stops at the van Dam's door. They have not presented a shred of anything that places DW in the home or an indication that he abducted Danielle.
Kidnapping must be proven or murder can't be. Has kidnapping been proven?
IMO, Jeff Dusek suggesting that we just have to believe that he got into the house undetected and got her out of the house somehow is asking way too much. It is the key to everything they claim happened subsequently and the key doesn't fit the lock.
