There are changes coming to the Nassau County Correctional Center.

County Executive Bruce Blakeman promoted Michael Sposato to corrections commissioner.

Sposato previously served as sheriff under Ed Mangano and was demoted in 2018 for jail mismanagement.

The decision comes months after a report found the private medical contractor Sposato brought in led to six inmate deaths.

Corrections Officers' Union President Brian Sullivan says it was one of Sposato's moves to cut costs.

"He came to work every day with a red pen - everyday it was, 'Well, what can I cut now?," Sullivan says. "They cut millions of dollars out of a place that's already behind from everybody else in the country."

Blakeman's office cited Sposato's experience in running the facility and implementing cost-cutting measures as the reason for his promotion.

Nassau Sheriff James Dzurenda resigned from office on Wednesday.

Blakeman appointed Undersheriff Anthony LaRocco to fill that position.
