We lack the details at this time to accurately assign a portion of teh blame to the Mother as yet. You do not know if she was "careless", nor do you know what she did/did not try to do to address her son's mental issues.
It's certainly possible she bears a meaningful portion of responsabillity, but thata hard to prove at this still-early (details wise) juncture.
She absolutely was careless. I don't care if she had them locked up, obviously it wasn't enough to stop him. She knew he was dangerous. His former babysitter accounted for her stating to him to "never take your eyes off Adam, not even in the bathroom". They were her guns, he was her son, mentally unstable and under her care and supervision. She is ultimately responsible for both.
