NAUGATUCK, Conn. — The chief medical examiner’s office has concluded that former state legislator Kevin DelGobbo died of natural causes linked to chronic alcoholism.

DelGobbo died in July at the age of 53.

The Republican represented Naugatuck for 12 years in the state House of Representatives and later served as chairman of the state’s Public Utilities Regulatory Authority. He also was chief adviser to Waterbury Mayor Neil O’Leary.
