The shooter's mother, Katheryn Nash, was initially talking with investigators after the shooting before retaining an attorney and cutting communication.
Yeah, he was a grown man and I'm sure that his mother had no idea that he was going to do something this horrible. The only thing that she might be responsible for is if he was, for whatever reason, not legally able to purchase guns and she knowingly purchased them for him and/or had knowledge that he had access to them. Just because he lived with his mom does not mean that she was responsible for or even had any control over her son. If he was 42 then she is a senior citizen who might have been relying on her son to help her for all we know.
