On Aug 9, 1927, Herman, with others, robbed an ice plant in Newton, KS, after which Patrolman Joseph Marshall of Wichita was killed. His death on Aug 9 is confirmed by Wichita PD. Herman was wounded in a gun battle sometime after and committed suicide on Aug 29, 1927. Some sources say the gun battle was a result of the ice plant robbery, others the result of a bank robbery (but not which bank and when).
