It is strange to me that he tried to buy a gun a few days ahead of time, knowing there were guns in the house. If he had easy access to guns at home, why would he try to buy one, knowing he risked discovery of his plan by doing so?
I wonder if he created a ruse to get his mother to access the guns at home, and his ruse worked—then the killing started.
Just a thought...
We have fingerprint technology with gun safes now — we ourselves are thinking of obtaining one to store our guns, as we have an autistic son who is now 11.
Would have perhaps helped this mother.
I still can’t figure out why she would take him to a shooting range. Just sounds a bit extreme to be teaching those skills to a kid like this.
