“I still want to kn0w where a 17 yr old came up with an AR-15”
He was 18 or 19, not 17.
His mother died in November so maybe he had some $$$ from her.
...
He had a job at a Dollar store, and he was living with a friend’s family.
Perhaps he didn’t have any family of his own left in the world if that’s where he went after his mother died. I wonder where is the extended family or if any.
