The Sandy Hook killer reportedly had robbed the murder weapons from his mother. That’s not the same as her buying them for him.
But yeah, I imagine they furnished Rodgers enough to let him live high on the hog. A gun or two was pin money to him.
OK - but the parents of the Sandy Hook killer allowed him to sit in his darkened room, watch violent video games and generally behave in an insane way. She also took her crazy kid to the gun range. Personally, I think these particular parents were as nutty as hell.
