Agreed. One of the victims is seen in her own video in what appears to be her bedroom on the third floor. She is next to the patio door on the third floor above the second floor kitchen patio door.
Since the male victim was found on the second floor, it seems likely that he was the first victim, and he may have opened the door. The three female victims were on the second and third floors.
"Officers at the scene on Tuesday described a bloody crime scene, particularly on the upper floors of the house."
