Kentucky Governor Andy Beshear delivered emotional remarks at a press conference on Monday, April 10, after a mass shooting at a Louisville bank killed four people, including one of his “closest friends,” he said.“Tommy Hill helped me build with my law career, helped me become governor, gave me advice on being a good dad,” Beshear said in an afternoon press conference, adding Hill was one of the people he spoke to “most in the world.”Beshear added that the state’s flags would fly at half-mast at state buildings until Friday evening to honor the four victims.Deputy Police Chief Paul Humphrey said police believed that the suspect was a “lone gunman” with a connection to the bank, and that it "appears he was a previous employee.” Credit: Louisville Metro TV via Storyful
