If I met with Mr. Lanza, it would have been to beat him to death.
He is one of two people responsible for Adam, and he failed. If he had been a real father, and not a "baby daddy check", maybe this would not have happened. The mother was a mentally ill alcoholic, and he knew it, yet he allowed her to be Adam's guardian.
Mr. Lanza, get ready, HUNDREDS of lawsuits are aiming at your head. Just like the gun your kid used, you worthless excuse for a parent.
