There's no way there were 2 bodies right inside the jdoorway who suffered horrific gunshot wounds that killed them instantly because it took 6 minutes for responding officers to even know there was a second body. (per the 911 call record)
I believe it would take them that long. Imo the lights were off and inside of the home was dark.
LE is not going to blindly barge into the home when they have seen someone right inside of the door dead on the floor from gunshot wounds.
They would slowly and cautiously enter maybe even waiting for more officers to arrive on scene before making entry.
They would have no way of knowing at that time if the armed shooter was still inside ready to shoot the officers upon entry.
By what Fitzgerald has said himself we do know both Denise and James were found in the same general area together. That is why he said he thinks the murderer kicked the phone away and it wound up landing closer to where Denise's dead body lay than closer to Jim's dead body.
Kicked cell phones arent going to go into different rooms and around walls and corners.. And he also has said he believes the killer/abductor only entered the home 5 feet in. Imo that would make him standing next to the head of Jim's dead body.
That would have to mean he had to have them both in his sightline immediately and was able to shoot both parents in seconds because both were in the same area close to each other at the time they were both murdered.
The commotion overheard on the enhanced 911 call was coming from Denise's phone but the commotion overheard of someone yelling for help was coming from another area or room from where Denise's cell phone was found per Fitzgerald. Which means the phone location was in the same area both parents were located and what was heard was happening in another area.
Imo that is how Fitzgerald knows Jayme was alive and inside of the home at the time when her parents were murdered.
They heard on the 911 call among the commotion going on at the time that was coming from another room or area of the home than where her parents lay dead and it was Jayme's (voice) pleas for help. Imo
