Suffolk County's police commissioner is set to move on to a new job.

Suffolk Police Commissioner Geraldine Hart announced Wednesday that she is resigning after three years on the job. She will leave her post May 7 to become the director of public safety at Hofstra University.

Hart is the first-ever woman to lead the Suffolk Police Department. She also spent more than 21 years with the FBI and was head of the Long Island Gang Task Force before joining the department.

When Hart took over the Suffolk P.D., the 2,500-member force had seen some turmoil. The department was being monitored by the U.S. Department of Justice over its response to the racially motivated 2008 murder of an Ecuadorian immigrant. Other incidents she faced at the time included the conviction of former police chief James Burke for beating a suspect - then covering it up - and criticism of her predecessor Tim Sini.

Some of the issues Hart said she wanted to tackle when she took over as commissioner included the opioid crisis and eradicating gangs, such as MS-13.

Suffolk Police Chief Stuart Cameron will serve as acting commissioner until a replacement is named.

The announcement of Hart's resignation comes just weeks after Suffolk police - and departments across the state - were required to submit reform plans. Suffolk's plan, which includes equipping officers with body cameras, was approved by county lawmakers on March 30, and submitted to the state.

Commissioner Hart was also interviewed extensively for News 12's Gilgo Unsolved special.
