I don't believe that this was LE. I am sure LE would have checked where their patrols were that morning. Almost 94 percent of mass murderers are done by males, with only 40 percent over 30 yoa. Motive is retaliatory based on rejection or failure. They do this to get some type of control over their life. They experience life time frustration, humiliation, and failure. Often unemployed, external blame, comes from a broken home, either by divorce or death of a parent, and may had a loss although it may seem small. He likes guns, weapons and violence, which may be real or fictional. History of substance abuse, depression, and other mental heath issues. Murder is centered around revenge fantasies. They plan, justify, and perfect their revenge, running the plan their head, which is long term and calculated. This gives them the sense of power and control. They have a low self image of themselves and lack of coping ability. Short term acute triggers are a loss of job, relationship, humiliation, financial issues, or bullying. This is the last straw mentality. He may be a loner, grandiose and obsessional traits, mental illness, or a sense of entitlements. I am sure that the person (s) that did this saw the children non-threatening or loves kids. I don't see the theory of family members killing other family members for the kids. I have a great suspension whom that might be.
