In a few short minutes a disgruntled employee armed with an AR-15 rifle fatally shot five colleagues at the Old National Bank in Louisville, Kentucky, before himself being gunned down by police.
The shooter was later identified as 25-year-old Connor Sturgeon, who had worked at the bank for years, first as an intern but reportedly knew he was about to be sacked.
Six people were killed, including the shooter, with nine being taken to hospital for treatment.
