A gunman who went on a rampage at a US bank, where six people including himself died, is believed to have been a popular student at school.
Connor Sturgeon, 23, was told that he was going to have his job at the Old National Bank in Louisville, Kentucky, ended before he carried out the attack, a source reportedly told CNN.
The gunman wrote a note to his parents and a friend saying that he was going to carry out the attack but it is unclear whether it was actually seen prior to the massacre.
