If it is taken as fact that 1. the two gunshots at 12:31 correspond to the killing of both parents, 2. the 911 call was made by Jayme (or less likely the assailant) some 20 minutes later, and 3. the call was the precursor to Jayme and assailant leaving the house within 4 minutes.... then it holds that the assailant knew about the 911 call but kept Jayme alive anyway. I think this is key. That combined with the 20 mins in the house makes me think this whole thing was about Jayme. The siege nature of the entry and shooting suggests an expectation that there would/could be guns in the house/some kind of resistance. I keep feeling like this played out almost like uplifting a hostage. If there is a personal phone or laptop (and I think there is at least a phone, which LE hope to recover) its possible these left the house too and if so I find it hard to believe the assailant would not know Jayme had them and/or would allow their removal unless it was in their interest to keep them from LE (that whatever was on them was more detrimental and/or that they were more immediately useful to the assailant than the risk of them pinging until such time as they could be destroyed). Like others have said, I've felt from the beginning that this was personal. All JMO.
