JOPLIN (AP) - The shake-up at the Joplin's Public Works Department continues, with the assistant director's resignation.
Jack Schaller resigned Monday, saying he will leave Aug. 30 to work for a private engineering firm in Joplin.
City Manager Mark Rohr has reassigned former public works director David Hertzberg and ordered disciplinary action against building inspection supervisor Steve Cope, which prompted Cope's resignation.
The city is investigating the public works department after it discovered $150,000 in code enforcement and building permit fees missing. Rohr also said thefts have occurred at the city garage.
The Joplin Globe reports Schaller did not mention the investigation in his resignation letter. City officials would not say if Schaller was disciplined as part of the public works probe.
