[FONT=&]"The security system records the activity anytime a window is open or closed," said McWilliams. "We know that there was a door open when the killer left the residence at approximately 1 a.m."[/FONT]
[FONT=&]So then what happened during those five hours between when her sister last talked to her, and the suspected killer left her home? The crime seemed too up-close and personal to be random.

From what I can remember, the time of 1am was the time the suspect left the house, but we were left to speculate as to how they knew this. I remember us talking about a neighbors camara maybe catching the perp leaving but I think it was a rumor. ( would have to go back and look). Much later in the investigation, it was reported that the 1 am time was from data from her security system. If I'm wrong, please correct me.
LE has not released whether the system registered a door or window opening to let him in .Just that there was no forced entry. So, either it was off and later turned on? ( doubtful, doesnt make sense). Or a door or window was open and he just came in? If it was on, and she let him in, that would be recorded in the system.
My thought is.... that her system was on and he entered through an open door. And there is no record of it. But recorded him leaving[/FONT]
