President McKinley was shot by Leon Czolgosz on September 6, 1901 but did not pass away until September 14, 1901. He was shot twice, one causing minor damage while the other pierced through his abdomen, pancreas, kidney and stomach. Only one of the bullets were taken out because the other couldn’t be found. Shortly after McKinley was shot, it look liked his health was improving and would live, but he ultimately didn’t make it. McKinley’s assassinations led to Roosevelt to succeed him
