Evidence found on Allen's electronic devices and in his writings point towards the theory he intended to target administration members in attendance at the dinner. His family members told law enforcement that Allen had sent them some of his disturbing writings before the attack, which prompted one of them to alert police. The writings did not specifically mention the dinner on Saturday. Another family member told investigators that Allen has made radical statements and that he frequently mentioned plans to do 'something' to fix problems with today's world.
