New Hampshire Attorney General Gordon J. MacDonald, New Hampshire State Police Colonel Christopher J. Wagner, and Seabrook Police Department Acting Chief Brett J. Walker announce that an arrest has been made in connection with the on-going death investigation in Seabrook, New Hampshire.

At approximately 6:20 p.m., on Wednesday, August 29, 2018, the Seabrook Police Department responded to a report of a motor vehicle collision involving pedestrians on Pine Street in Seabrook.

An autopsy will be conducted today to determine the exact cause and manner of Mr. VanDalinda's death.

Ms. Costello, has been arrested on several felony and misdemeanor charges. Those charges consist of:
