Excerpts from the ChicagoTribune.com:

David Griffin has resigned from his position as Oak Forest’s fire chief after being put on leave earlier this month.

In a March 8 letter to the mayor, Griffin said that he was resigning from his position as chief due to personal reasons, but asked that he immediately return to the department with his rank of lieutenant.

Griffin, who was named to the chief’s position in June 2014, was placed on paid administrative leave March 3 after some purchase invoices for the department were red-flagged as requiring further investigation, City Administrator Troy Ishler said. The invoices were not paid by the city. Ishler said Griffin remains on leave from the department, and it has not yet been determined when he will return as a lieutenant.

The city council may be asked at its meeting Tuesday to approve a new or interim chief. John Janozik is the department’s deputy chief.

Griffin, 43, of Tinley Park, has been with the fire department more than 15 years and has held the rank of lieutenant since 2012. He was appointed chief to replace retiring Chief Terry Lipinski.
