I have been sitting here looking at the front of that house, the windows, the small front porch and imagining in the dark of night what transpired, I picture JC inside looking out the living room windows and if he had any suspicion of what he was seeing why did he go to the door. Also, if he was in the living room watching TV or at least with the light on the perp/perps could see him really well and would know DC was or wasn't there with him.
I wonder if one of the people was a woman who was there to take Jayme while the man took out JC and DC.
I can think of one good reason, which I'll explain below.

Still looks like a bullet hole to me in the 2nd to the right window next to the stairs. I've seen many photos and it is in all of them. Doesn't fit with the LE statement of 5 feet in but to me it looks like a bullet hole. Zoom in closer if you know how
Thanks for pointing that out, it gave me fresh perspective to look at.
Jayme was already sleeping, and the parents were getting ready to go to bed when they heard a car pull into the driveway. Looking out the window and seeing whose car it was caused both to react. Denise ran to get her phone (which was in whichever room that window leads to) and James went to lock the door (which they may have normally kept unlocked. The guy may have expected everyone to already be asleep because they had work/school in the morning, and knew they never locked their doors. His plan may have originally been to slip in through the front door and kill them in their sleep.
Denise calls 911 just as the guy gets to the front door. He hears the lock click and starts yelling for James to open the door. She is so upset that she doesn't say anything on the phone, and just looks out the window to see what's happening. He starts kicking the door and sees her in the window as the door gives in; the sound of the door/frame breaking startles Denise enough to make her drop the phone which disconnected the call and sends the phone bouncing several feet away from her. He quickly shoots James through the open door way and then turns and shoots her through the window.
Jayme hears the noise and comes out of her room to see what's happening. She sees her father laying there and runs over there because the doorway is blocked by the shelves and she doesn't see the guy in the doorway. When she gets there, he just grabs her and leaves. The reason they don't believe he went in more than 5 feet is that there was blood all around James' head and anyone going past him would have to step in it and leave tracks. The reason they don't think Jayme resisted is that they can see her footprints in the blood and they lead straight to the door.
I know this would take a lot of luck and coincidences, but it is slightly possible. MOO
ETA: After reading oceanblueeyes' post, I realized that this doesn't explain how the 911 call helped tell them that Jayme was there and alive, so I'll change it just a bit. Maybe she heard the noise and ran to Denise (who seems like she may have been Jayme's source of comfort) and yelled something then or when the door burst open. She may have waited a moment until she thought the guy was gone to go check on her father (or may have left through the glass doors), only to find he was still there.
