GEORGETOWN — Three Delaware men were arrested after investigation into a 2017 shooting death in Massachusetts, Delaware State Police said Thursday.

The Essex District Attorney’s Office, Essex State Police Detective Unit and the Haverhill Police Department conducted an investigation that ultimately yielded information about potential suspects in Delaware, police said.

Investigators reached out to the Delaware State Police Homicide Unit to coordinate the identification and apprehension of the suspects, spokeswoman Master Cpl. Melissa Jaffe said.

Nicholas A. Mandato, 20, of Dagsboro, was arrested on a warrant out of Haverhill District Court by State Police Homicide Unit. He waived rendition and returned to Massachusetts Wednesday.

Two additional suspects were arrested yesterday by the State Police Homicide Unit. Thomas J. Warner, 21, of Selbyville, turned himself in to Troop 4 in Georgetown and Kenneth J. Pitts, 18, of Frankford, was arrested without incident in Bethany Beach. They are in custody at the Sussex Correctional Institution in Georgetown.

In Delaware, all three suspects were charged with fugitive from another state for the alleged homicide in Massachusetts.
