Who assassinated President James A. Garfield?

Charles Guiteau assassinated President James A. Garfield. Guiteau was a disgruntled lawyer who believed he deserved a political appointment for his support of Garfield during the 1880 presidential campaign. When his attempts to secure a position were repeatedly ignored, he grew bitter and delusional, ultimately leading him to shoot Garfield on July 2, 1881, at a train station in Washington, D.C. The president's injuries were initially not deemed fatal, but due to medical mishandling and infection, Garfield's health deteriorated, leading to his eventual death on September 19, 1881. Guiteau was tried and convicted for the assassination, and he was executed by hanging on June 30, 1882.
