IIRC Tyler said in her police interview on camera on 11th July that she had driven back alone from Texas to Az. There also is no sign of that jeep in overhead footage from 11 July 2019 so I wonder where it was that day?
You've hit the nail on the head of something that has bothered me since I first saw that footage: Why is the garage door open?
This footage is from the one who arrived first:
Justin Lum Fox 10 Phoenix on Facebook Watch
This footage is from the one who arrived second but 'interviewed' Alex:
The garage door is clearly open in both videos. Early morning. Gated community. In the second link, we see LEO approach the community in his cruiser. We pass numerous homes in the area with visible garages, all closed. But, this house, where a man has been killed, and another man mentions always carrying his gun. This house wherein a young woman claims she has a bat for her protection to feel safe. This house has the garage door open on this July morning. As the garage is open in the footage, we can get a better picture of the vehicles inside (or lack thereof). Alex's truck is parked in the driveway. Lori's Infiniti QX80 in the left side of the garage, no vehicle visible in the right side. Why is the door open?
MOO: There may be a keypad for the garage outside. We know from the subsequent police report, Tylee is reported to have entered the home through the garage to get items from Lori's room before they left to take JJ to school. If she used the external keypad to enter, and quickly left in the rental with Lori, there wouldn't be a way to close the garage (remote opener/closer). Why would Lori take the rental? It could have been sitting in the driveway where Charles left it and would have been in the way. She knew he wouldn't need it and it would have been tedious and time-consuming to move it to get her own vehicle out. If the door had been closed, we would not know which vehicles were/weren't present.
The question remains, where was her Jeep on the morning of July 11, 2019? I had at one point thought that the door being open indicated that Tylee removed the Jeep and drove it somewhere to meet up with Lori in the rental for some purpose. Alex's truck would have had to have been moved and replaced as there's no way to get a Jeep past it if parked in the right side of the garage. But that doesn't make as much sense as Tylee's reported re-entry of the home via garage.
Where was Tylee's Jeep?
