She has continually shown her commitment to the communities in Atlantic County by participating in community events. Thank you for your service, Chief Assistant Prosecutor Halayko and I look forward to watching you practice your leadership skills in this new role,” said Acting Atlantic County Prosecutor Cary Shill.

“All of the office’s assistant prosecutors and interns that I have had the privilege of working with while serving our county are so special to me—each and every one of them. They are my sources of inspiration to work harder and I want to honor them,” Chief Assistant Prosecutor Halayko said.

Chief Assistant Prosecutor Halayko said she did not reach this level in her law enforcement career alone. She was inspired by all of the chief assistant prosecutors serving in this role when she started her career at the office in 2010.

Melchionne, J.S.C. in the Bergen County Family Division. Chief Assistant Prosecutor Halayko is barred in both New Jersey and New York.

“On my journey, there have been so many who have come before me–and those who are currently serving– and I would be remiss if I did not show my gratitude for their contributions and guidance,” Chief Assistant Prosecutor Halayko said.
