After Miss D posted about the alleys and the CS tape, I doodled with the alleys. And it'd not making any sense.

Blue dots with white centers: entrance/exit to alleys, Red lines: alleys
There are none of those 5 foot utility easements that were really common in the older parts of Scottsdale: these were basically for electrical and telephone lineman to get to overhead lines, that were hung over shared property lines, from the alleys.
There are none that I can find connecting to either alley, both behind and directly across the street from AF's home. I zoomed in the shared property lines on both of those alleys. You go into either alleys and you come out of them, unless you hop a fence.
Did LE tape off the alley across the street because the security camera caught the perp leaving AF's house and going down it? "1:05 am security camera catches the perp leave".
If the perp took the alley across the street, it makes absolutely no sense.
Why take that alley across the street when it just exits on 84th place and out to Earl Drive? Perp could get on Earl just by exiting onto the alley behind AF's. No lengthy walk, no possible dogs.
Does the perp know the area well enough that he knows where the dogs are and that they're going to be quiet?
If he had a car, you'd think he'd park it nearby. 84th Place would seem like the most convenient place where that alley exits, but it's a culdesac, a strange car would draw attention.
From the clues:
I'm a murderer, I just killed someone. I have blood evidence and possible scratches on me. I have stolen property with me. I walk out the front door of my victim's house, I am on foot, I walk across the street to the alley..................
WHY?
Is it because the back gate to the home I live in is on that alley? I'm staying with friends who have a back gate that is on that alley? Do I live in the neighborhood? Will my presence NOT be considered out of place if I am noticed?
From a criminal mind:
I'm a murderer, I just killed someone. I have blood evidence and possible scratches on me. I have stolen property on me. I walk out the front door of my victim's house, I am on foot, I get the heck out of that area as quickly as possible. I go straight to Earl Drive and I disappear.
Does that make sense? The whole point for the perp is to get out of the area without being seen ASAP.
