Andrew John Engeldinger (c. 1976 – September 27, 2012), a 36-year-old resident of Minneapolis for twelve years, was raised in Richfield, Minnesota and graduated from the Academy of Holy Angels. He was formerly employed by Accent Signage Systems, but recently fired from the business. According to neighbors, Engeldinger was a loner who never engaged in conversation with anyone, while a former coworker described him as not eating lunch or taking breaks with other employees. Engeldinger's parents and other family stated that he had some sort of mental illness and resisted treatment, eventually becoming estranged. Early reports state that he began shooting upon returning after being fired were incorrect, authorities said Friday, according to the NBC article. He was in the front office after being fired, and then went to the loading bay, and authorities said there were clear indications he may have targeted certain people. A search of his home uncovered packaging for 10,000 rounds, indicating that he was heavily armed and had practiced shooting quite a bit.
