The 25-year-old bank employee who went into work armed with an AR-15 rifle and killed five colleagues "knew he was going to be fired" and wrote a note to loved ones before the shooting, it has emerged.
Connor Sturgeon had worked on and off at the Old National Bank in Louisville, Kentucky, US, for years, starting out as an intern before joining full time last year, according to his LinkedIn profile.
He was killed in a shootout with police.
