Question: How was the man investigated by Keith Beauchamp killed?

full_context: Document 1: Lynching of John Evans: On Tuesday, November 12, 1914, John Evans, a black man, was lynched in St. Petersburg, Florida, by a mob of 1,500 white men, women and children. Evans was accused of the murder of Edward Sherman, a white real estate developer, and the attack of Sherman’s wife, Mary. After word of the attack spread, and Mary Sherman claimed her attackers were “two negroes,” a citywide search ensued. Suspicions immediately led to John Evans. Two days after the murder, a posse consisting of some of the city’s most prominent and well-respected members stormed the St. Petersburg jail, threw a noose around Evan’s neck and marched him to his death. He was never given a fair trial. Evans was hung from a light post on the corner of Ninth Street South and Second Avenue. At first, Evans kept himself alive by wrapping his legs around the light pole. But then, an unidentified white woman in a nearby automobile ended his struggle with a single bullet. Though the shot was fatal, the rest of the crowd began shooting at Evan’s dangling body until their ammunition was depleted.
