Anyone else think those 2 gun shots were what killed the dad and the mom was killed another way? I think most people would shoot at least twice at an target and there were no other gunshots heard unless the neighbors slept through it.
I think the perp may have banged on the door and both James and Denise went to the door. Dad wouldn't open the door, so the perp broke in the door, and shot dad killing him and shot Denise only wounding her. She was able to run to another area, attempted the 911 call and died from her wounds.
I believe all was done in total rage. Perp was mad at someone, and I believe it was James. I do Not know why he was angry with James, maybe work related.
I don't feel like anything was planned. I believe Jayme was taken on impulse. jmo
