GREENFIELD — The driver of the car involved in a collision with a Greenfield police cruiser on Sunday evening, Oct. 1, has died.

James Arcellana, 29, believed to be of New Hampshire, was pronounced dead on Wednesday at Baystate Medical Center in Springfield. His official cause of death will be determined by the office of the chief medical examiner, according to Mary Carey, a spokeswoman for the Northwestern District Attorney’s Office.

Arcellana was driving a Subaru west on Sanderson Street when he attempted to cross High Street, resulting in a collision between his vehicle and a southbound Greenfield cruiser. Arcellana and a passenger of the Subaru were treated at nearby Baystate Franklin Medical Center and later at Baystate Medical Center in Springfield for their injuries. The Greenfield police officer was treated for non-life-threatening injuries at Baystate Franklin Medical Center, and later released.

Carey said the District Attorney’s Office will not be releasing any other information at this time, including the name of the police officer involved.

Because the crash involved the local police, the cause of the collision remains under investigation by state police detectives assigned to the Northwestern District Attorney’s Office, the State Police Collision Analysis and Reconstruction Section (“CARS”), and the State Police Crime Scene Services Section.
