The 38-year-old Gloucester man taken by Med-Flight to Boston's Tufts Medical Center with life-threatening injuries Friday night remained hospitalized there in critical condition Sunday, city Police Chief Leonard Campanello and Tufts officials confirmed Sunday.

And the driver of the car that struck him is due to face charges Monday in Gloucester District Court.

Police this morning identified the victim as Robert Frazier, who is from Gloucester but is listed as having no known permanent address. Frazier sustained multiple serious injuries, including brain injury, Campanello said Sunday. 

According to police, Vincenzo Mannone, 27, has been charged with operating under the influence of drugs and failure to keep right in connection with the 6:45 p.m. crash, which occurred on Maplewood Avenue in the area of the former Maplewood School.

Gloucester Police, Fire, and EMS all answered the call for a report of a motor vehicle accident involving a pedestrian, and responders who arrived at the scene found Frazier on the ground, with head trauma and other injuries.

Campanello's initial statement Friday night indicated that Mannone remained at the scene after the crash. But a Gloucester Police investigation found that he was under the influence of drugs, and he was arrested at the crash site.

He was transported to the Gloucester Police Department for booking and was held pending bail.

The case remains under investigation by the Gloucester Police and Fire departments, while the Massachusetts State Police Collision Analysis & Reconstruction team  was also called in to join in the investigation.

Campanello also noted that, while the crash occurred on Halloween night, it was not in any way related to the city's Trick-or-Treat Night activities.
