I'm studying what I can find for exterior shots of the home.
Here's an FYI about homes in Colorado Springs and the surrounding area (I've had four). New construction is very similar and the garages are snug. Two car garages barely fit two cars in a lot of cases. Three car garages, often the third stall is used just for storage, bikes, sporting equipment, etc, especially busy families with children. Many larger trucks are simply too big to park in these tight garages. Additionally most HOAs have prohibitions against street parking overnight. That being said, even with a three car garage, three cars would be a challenge to house.
What I'm wondering about in this case is 1. the location of the gate. (Best I can tell, theirs might not be visible but could be inset on the far side of the garage. I believe I can see each of their side neighbors' gates.) And 2, where the family keeps their garbage cans. I ask because surely an HOA prohibits them from being visible from the street. Garage space might be at a premium. Perhaps their trash cans are kept behind the gate.... jumping off what TS said in her Open Letter of Guilt, might there be a slight blood trail to the garage and to the gate, from multiple trips to THE TRASH CAN?
It's possible items then went out with the regular trash pick up (on Thursdays, based on curb placement of neighborhood trash cans in MSM photos) or those items could have been removed from the trash and relocated on Monday.... like to a pond.
