I thought that I had read that some place too, but it's not in the lawyers statement and she seemed to include all sorts of granular details. Guess it must have been turned off since "she has no access to arm or disarm the system" - and when she got home from her trip and entered the house, one would assume you'd have to turn off the alarm. Or you know, the alarm goes off.
Interesting that the lawyer mentions they have "no idea whether McCoy was able to live stream or see the incident...". If the power was off, to your point, the lawyer and victim should know that the system was not on so Shady wouldn't have seen anything.
Also, since there was not forced entry by the assailant, but this happened not long after she got home from Paris, maybe she just left the door open? If the power was off and the alarm was off, the assailant obviously didn't use a keypad to enter the house.
Such a strange case! This will make a good 8 part Netflix docuseries in a few years ?
