Excerpts from shawlocal.com on August 18th:

John-Paul Schilling is out as Carpentersville’s fire chief, officials announced Wednesday. According to a brief statement, Schilling resigned. He was hired as fire chief in June 2016.

Battalion Chief Rick Nieves has assumed the role of interim chief and he declined to comment on Schilling’s resignation.

Schilling is the village’s second top public safety official to resign this year. In March, Police Chief Patrick Hoey was replaced by Deputy Chief Todd Shaver.

At the time, the village manager said the village was moving in a different direction and thanked Hoey for his service and wished him well, and that Schilling’s resignation did not involve any severance package. He added that the village hopes to have a new chief named as soon as possible.
And from the patch.com:

Former Elmhurst Fire Chief Bill Anaszewicz, who left suddenly in early April, will become the fire chief in Carpentersville starting on Monday.

Anaszewicz was only chief for six months when he submitted his resignation letter April 4, saying he was retiring effective immediately and that he was dealing with family medical issues.

In a news release five days later, the city did not say Anaszewicz was retiring, but rather that he was resigning after finding a new employment opportunity.

Carpentersville, in suburban Kane County has about 10,000 fewer people than Elmhurst.

Anaszewicz and city officials never explained the chief’s quick departure.

In a statement to the Carpentersville Fire Department, interim Fire Chief Rick Nieves called Anaszewicz a “bright and experienced firefighter and leader.”

Anaszewicz has 29 years of experience as a firefighter, 26 of them in Elmhurst.

Last October, Anaszewicz was appointed as the chief after serving as interim chief for a year and a half.
