He s dead. He didn t make it,  Flint said.  For his family and everything, I feel bad, and we ll be there for them. MENTALLY ILL BUT IGNORED? The roommates lived near the gunman, and Flint said that their neighbor had been shooting a lot of rounds recently. The crazy thing is that the neighbor has been shooting a lot of bullets lately, hundreds of rounds, large magazines,  Flint said.  We made it aware that this guy has been crazy, and he s been threatening us and everything. I just feel like there maybe should have been more effort put into stopping things like this.
