Its odd that the family had a statement prepared practically as soon as the name was released.
Exactly. It suggests a possible coordination between the police, the family, and the media to control the information being released. If the family released the statement 2 days later it would be too late in a PR sense, because that would be 2 days of the public seeing a Muslim name attached to a mass shooting and of course most assuming this was terror related.
What's also a bit odd is that they still haven't revealed if the attacker died by suicide or by police fire. That would be pretty easy to figure out quickly. Or maybe they're waiting for the autopsy, who knows.
