Its why you should send in a tip to both fed and local LEOs. Perhaps a call to any mental health orgs in the area.
And this relative or friend that tipped the FBI should get in front of a microphone and proclaim what has happened.
They didn’t even bother to pass the tip to the field office.
It sounds like local LEO already knew the shooter all too well.
And had known he was a bad seed since the kid was 12
I would call the police and/or the county sheriff’s office.
I wouldn’t call the FBI now if ISIS were setting up mortars in my front yard.
