I still have to wonder if its possible that Sidney was in the apartment hiding when Heather got home from her date. When I look at the tight timeline of the pings regarding their truck driving to PTL and back home, and the tiny timeframe in which the truck would have arrived there vs when Heather's phone died or lost service completely, it makes me still think there's a possibility that Sidney could have driven Heather's car to PTL from her apartment and Tammy drove their truck to PTL from their house to pick up Sidney. I'm trying to remember why police are so confident that Heather was the one that drove her car to PTL. Did they capture her driving on camera? If they're basing it on her cell pings, Sidney could've had her phone...
