Several enslaved people escaped from the farm of Richard Phillips in New Madrid, Missouri, including Jim Gray, who was apprehended in Union County, Illinois by local slave catcher John B. Jones. Gray, however, was later rescued from federal custody in Ottawa, Illinois. A fugitive slave case ensued, in which several anti-slavery activists were indicted (including John Hossack, Dr. Joseph Stout, Claudius B. King, James Stout, Hervey King, and E. W. Chamberlin). Hossack received the longest sentence --10 days in jail for violating the 1850 federal Fugitive Slave Law.
