How does this theory sound to you as a former LEO?
It's very early Monday morning and it was hot but as it would be in the afternoon when it gets to 100-102. And being that it is summer, kids are out of school. Two 16 to 19 year old bad boys in that same neighborhood only go out late to avoid heat and have two options of things to do. They can do something bad or they can do something stupid. When they do bad and stupid at the same time, there are big problems.
Furthermore, they are armatures and armatures may not want to burglar a house, and instead pick a shed in the back yard. Teenage boys like tools, bikes and lawn equipment.
Before they leave the house, The smart one grabs his dad's tools. The dumb kid grabs his dad's gun.
They break into the shed and the dumb kid is scared and when the deputy comes home, the dumb kid gets more scared and a lot dumber.
Dumb kid shoots the deputy.
They run back to their houses. The house(s) are close as no one wants to run among way in the heat, especially when Round Rock Police, Austin Police and two,sheriffs departments looking for you.
Your perps are in a house within 3 blocks of the murder scene, and they are crapping in their pants.
And by this point they are being protected by their parents.
armatures and armatures = amateurs
I read it. You have quite an imagination and lack basic spelling skills. And the poster did not make a, “Good point”, but instead provided you a factual description of the term, “Robbery”.
