Just heard on local news, no link yet, that the parents may be charged with a crime as the son had access to the gun. That may be one reason no name yet.
I'm okay with no name yet. It gives more focus to the victims, even though 2 haven't been named as they are underage. It does allow time for media attention to slowly shift elsewhere while keeping the 2 underage victims somewhat protected from media, hopefully until mostly recovered.
The name will come out, and hopefully by then, anything LE may have found for his motive, ie: computer use, cell phone, etc...
Prayers for all harmed and their families.
ETA: Well, there are links all over the internet. Here is one:
