Five men hatched the scheme to rob the guests at the Harris Mansion. One (C.W. Katzschman, not pictured) was killed by Officer Brown, Harold Wilson was arested by the Police at the house, and three were arrested after a nationwide investigation.
In all of the chaos at the Harris Mansion, two of the bandits, Vernie Katz and Clyde Henderson, managed to evade capture and fled to Los Angeles. They were arrested by the LAPD after a nationwide search and returned to Champaign County on December 7, 1929. The investigation involved the Chicago Police Department, the Los Angeles Police Department, and the Federal Bureau of Investigations.
