Those are my thoughts also, 28 years old and never been in trouble with the law before and now this, yes I think they should look a little closer and they may very well be. These things take time, plea bargains and what have you to bring out the whole story.
The family says he’s never been in trouble with the police, and the sheriff says the same with the qualification that they had “questioned’ him before about other caseS. So that’s at least a red flag.
He’s too stupid not to give up any accomplice he might have had. Why would he have used his own cell phone instead of a throwaway from 7-11. Not a smart criminal at all.
I would be willing to bet that this was not his first rodeo. One does not plan, to the point of buying untraceable phones, to rob and shoot two someones in cold blood on their virgin crime spree. He may not have been caught but have a feeling that he had been down this road before.
