Yes, I posted this closeup of the ledge outside the railing on the (3rd floor) back porch several threads ago. It's a crop from a Fox article that had a ton of pix:
Moo, but anyone lurking up behind the building (C side, in FF lingo) in the Queen St. parking area adjacent to some of the larger apt complexes, may have had a clear view of both of the 3rd floor bedrooms and also the 2nd floor sliding glass door, which I believe police said was the point of entry (?)
It's conceivable that a stalker/Killer could have been watching the house for some time. Perhaps even before they took the Uber to go get a 1:30AM snack.
IMO, police should have opened up their window of video interest to many hours before the incident. Maybe even days, if there was someone who had cased the area earlier.
JMO.
