The suspect is believed to be Robert Card, a 20-year US Army veteran from Bowdoin Center, Maine.
(according to Telegrams so take with grain of salt)
EDIT: Name confirmed by news.
According to law enforcement, CARD recently reported mental health issues to include hearing voices and threats to shoot up the National Guard Base in Saco, ME.
Apparently he wasn’t a firearms instructor. At least thats what I heard on the news an hour ago.
Probably the guy who runs shooting ranges
What
Sometimes news stories will confuse instructors and range officers. Instructors are supposed to teach you something, ros are supposed to be the people who pay attention to what’s going on and make sure everything’s safe/legal.
