Police say 29-year-old Travis Reinking was nearly naked, only wearing a green jacket, when he opened fire outside the restaurant on April 22 and then stormed inside. On May 23, 2017, Reinking wrote, "These people told me that you guys signed a non disclosure agreement, to hide it from me. On Nov. 12, 2017, Reinking sent the message, "Dad, I got a place out of town now, I'm going to need to get my firearms back from you somehow." But the document also says Reinking did not believe he had the authority to keep his son's guns once Travis Reinking demanded them back. After the attack, Travis Reinking was ordered to receive treatment in a mental facility for schizophrenia.
