That followup story makes it seem more likely that they were burglars. Before that, we had only the shooter's word that they broke in and weren't invited. We also have only his word that he has suffered multiple burglaries.
We'll never know what really happened, because there is no way this is going to trial. He's guilty as a mouse in a flour barrel, by his own admission.
The kids being burglars, if they were, is no excuse for murder. If it were, we couldn't prosecute ganstas for shooting one another.
