PORT CLYDE – A Massachusetts woman injured when a car slammed into her family on a Port Clyde wharf has been released from the hospital.

Allison Gold, 50, of Cohasset, Mass., is no longer a patient at Maine Medical Center in Portland, according to a hospital spokesman.

Gold’s son, 9-year-old Dylan Gold, was killed after a car driven by Cheryl Torgerson hit the family as they waited for a ferry to Monhegan Island on Aug. 11.

A preliminary accident report into the deadly collision near the Monhegan Boat Line dock said there was no immediate indication why Torgerson, 61, of New York City, sped through a series of crashes before her car finally came to rest, pinning the boy’s mother against another car.

The brief accident narrative describes how Torgerson’s car hit a 2012 Honda that had stopped in front of her and pushed it out of the way, then hit the corner of a building before hitting Jonathan Coggeshall, 68, of Port Clyde, who was standing alongside the building.

The car continued to accelerate past the building, first hitting six parked cars, then three people walking on the dock. The car knocked Wyatt Gold, 6, and Dylan Gold into the air. Wyatt was thrown between two parked cars, but Dylan landed on the ground and was run over, the report said.

When Torgerson’s car finally stopped, the boys’ mother was pinned between it and a parked car.

Dylan Gold died on the way to the hospital.

Torgerson was not injured. The report notes that results of a blood test, required in all crashes with serious injuries, is pending. Torgerson told police she doesn’t know what happened.
