Here’s what I think happened. Possibly a meth head was trying to rob the house and had cased it before. Kicks down door, shoots dad, ties mom up to chair and asks her about loot in the house. Meanwhile Jayme is in her room hiding, but terrified. She calls 911, phone is taken away by perp ( who finds her). Doesn’t have time as they already had killed both parents and realize police on way. Quickly grab Jayme ( possibly for sexual reasons). Unfortunately, I don’t think this will bear well for Jayme. They get away quick bec. it is a person in the community. Possibly someone with land/ barn etc. I
Hope this isn’t the scenario, but if it is, unlikely that she is alive.
