The Islip Town deputy supervisor -- picked by Supervisor Angie Carpenter three weeks after her swearing-in on March 1 -- has resigned, Carpenter confirmed Wednesday.

John J. Carney, a Republican who has worked for the town for about 22 years, "asked to be relieved of his duties," Carpenter said of his resignation on July 1 from the deputy supervisor's position. That role is unpaid. Carney, who was paid $101,717 in 2013 as the town's public safety commissioner, will remain in that post, Carpenter said.

Bill Mannix, executive director of the town's Industrial Development Agency, was sworn in as the new deputy supervisor on July 2.

Neither Carney nor Mannix returned calls seeking comment.

Carney's resignation came after public questions were raised at a town board meeting on June 23 about Carney's residency status when he was sworn in as deputy supervisor.

Allegations were made at that meeting by East Islip resident Patricia Montanino that Carney was a resident of the Town of Babylon at the time he was appointed. The position requires its holder to be a resident within the Town of Islip at the time of appointment and throughout the term, according to Islip Town Code.

Carpenter said the town attorney's office investigated those claims and said Carney "met the legal definition" of being a Town of Islip resident and was transitioning to an apartment in Bay Shore, where he had signed a lease within a week of his appointment.

"It may have been a matter of weeks when he was in a transitionary period," Carpenter said of Carney's residence, an issue she called "personal." She said she did not seek Carney's resignation.

"I didn't question his motives, why he was asking" to be relieved, Carpenter said in a phone interview Wednesday morning. "I said, 'Fine. If that's what you want.' "

Carney began his career with the town in 1993 as a hazmat team leader and spent 16 years as a mechanic at Long Island MacArthur Airport, according to his resume. He was appointed by the town board in January 2013 to public safety commissioner days after former Republican Supervisor Tom Croci, now a state senator, took office.
