A Minneapolis man and shot and killed four former colleagues and himself on Thursday at what is believed to be his former company. Four other people were wounded, three critically. The victims' bodies were found shortly after officers arrived on Thursday afternoon, and Minneapolic Police Deputy Chief Kris Arneson said officers never fired at the shooter. A former employee said the gunman was an employee of the firm who had been laid off on Thursday morning. The shooter was known to police before the incident and, according to a source, police suspect he may have been targeting specific co-workers at Accent Signage in his shooting rampage.
