NANTUCKET, Mass. — A former Nantucket 911 dispatch supervisor told the Select Board on Wednesday that he had filed a complaint against Town Manager Libby Gibson with the Massachusetts State Ethics Commission.

Patrick Considine, who identified himself as the former assistant supervisor in the town's emergency communications department, said during public comment that he filed the complaint on Monday. He said Gibson had "once again inserted herself" into a matter involving her husband, Deputy Police Chief Charles Gibson, by commenting on issues that Considine said are in litigation.

"In my opinion, Town Manager Gibson should have recused herself on multiple occasions throughout these proceedings," Considine said.

He said Gibson had emailed him at his personal address about pending litigation and that the email contained what he called an inaccurate timeline of events involving her husband. He said her involvement raises conflict-of-interest concerns.

Considine also said his efforts to raise concerns with the Select Board had been met with resistance from Gibson and Deputy Town Manager Rick Sears. He said several senior officials should have been placed on administrative leave pending an independent investigation.

"Pending litigation should not become an excuse to avoid accountability," he said.

Board members did not respond to his remarks, and the board moved on to its agenda after public comment closed. The Signal has not independently confirmed that a complaint was filed.

The town fired Considine in April, a day after he publicly accused Police Chief Jody Kasper of retaliation at a Select Board meeting, the Nantucket Current reported. The Select Board later denied his grievance and upheld the firing, according to the Current. Kasper said at the time that she had a responsibility to address "concerning behavior," and town officials declined to discuss what they called a personnel matter, the Current reported.

The Nantucket Current has previously reported that Charles Gibson is married to the town manager.
