On Saturday the Sun-Times ran a small item about a man who had set himself on fire during rush hour Friday morning near the Ohio Street exit on the Kennedy. His identity has still not been officially determined, but members of the local jazz and improvised music community say they are certain it was Malachi Ritscher, a longtime supporter of the scene. Bruno Johnson, who owns the free-jazz label Okka Disk, received a package yesterday from Ritscher that included a will, keys to his home, and instructions about what should be done with his belongings. Johnson, a former Chicagoan who now lives in Milwaukee, began making calls. Police are still awaiting the results of dental tests, but Johnson says an officer told one of Ritscher’s sisters that all evidence pointed to the body being his; his car was found nearby and he hadn’t shown up for work since Thursday.
