Cats5Vegas, Fairy1 and I visited the Anthem portion of Henderson - including SCA.
Thoughts:
SCA is very confusing. To park where Steven's car was found, requires either a map OR lots of in-and-out investigating to find "just the right place". Parking there randomly on a first try, would be like winning the lottery.
Homes on Evening Lights are so close together, it would be hard to pass gas without your neighbor knowing - let alone commit a crime. I don't think there's more than five or six feet between the homes. There's no real landscaping; just rocks and desert plants. There may be grass in the back yards. You can't walk silently on the rocks. They crunch.
At the top of EL, there's a path. There's also one 2/3 of the way up the street, on the west side. I originally believed they allowed access to the golf course, but they are fenced - solidly. They are also just rocks, not paving stones. It would, however, be possible to use the short walls to help oneself jump over the fence. We didn't try that. We're smart that way.
There are many areas on the slopes surrounding Revere Golf Course that are heavily vegetated and which could hide something. But it would take good searchers with heavy equipment to navigate them. I don't believe Steven's family would have been capable of searching all of the slopes, safely.
On the northwest corner of Mr Security's home, is a piece of equipment that looks EXACTLY like the two cameras on the front of the home. If it's a camera, it would have captured Steven's car parking, and whoever got out of it.
The cul de sac "circle" where Steven parked, is very small; smaller than it looks in the images.
There are three homes in the subdivision west of the cul de sac, which would have looked directly at Steven's car while it was parked there - every time they looked out their window. I hope the residents were questioned.
