On July 25, 1903 a mob lynched Jennie Steers on the Beard Plantation in Louisiana for supposedly giving a white teenager, 16 year-old Elizabeth Dolan, a glass of poisoned lemonade. Before they killed her, the mob tried to force her to confess but she refused and was hanged. (100 Years at Lynching. Ralph Ginzburg)
Laura Nelson was lynched on May 23, 1911 In Okemah, Okluskee, Oklahoma. Her fifteen year old son was also lynched at the same time but I could not find a photo of her son. The photograph of Nelson was drawn from a postcard. Authorities accused her of killing a deputy sheriff who supposedly stumbled on some stolen goods in her house. Why they lynched her child is a mystery. The mob raped and dragged Nelson six miles to the Canadian River and hanged her from a bridge. (NAACP: One Hundred Years of Lynching in the US 1889-1918)
Ann Barksdale or Ann Bostwick
The lynchers maintained that Ann Barksdale or Ann Bostwlck killed her female employer in Pinehurst, Georgia on June 24, 1912. Nobody knows if or why Barksdale or Bostick killed her employer because there was no trial and no one thought to take a statement from this Black woman who authorities claimed had ”violent fits of insanity” and should have been placed in a hospital. Nobody was arrested and the crowd was In a festive mood. Placed in a car with a rope around her neck, and the other end tied to a tree limb, the lynchers drove at high speed and she was strangled to death. For good measure the mob shot her eyes out and shot enough bullets Into her body that she was “cut in two.”
