PORTLAND – The medical condition of a Massachusetts woman who has been hospitalized at Maine Medical Center since she and her two sons were struck by a car in Port Clyde on Sunday has been upgraded to satisfactory.

Allison Gold, 50, of Cohasset, Mass., had been in critical condition earlier this week, but by Friday afternoon her condition was just one step short of allowing her to be released, according to a hospital spokeswoman.

One of Gold’s sons, Dylan Gold, 9, died on the way to a local hospital after the crash. Her other son, Wyatt Gold, 6, was treated at Maine Medical Center and released Tuesday.

Police have yet to determine what caused Cheryl Torgerson, 61, of New York City, to lose control of her Infiniti G35 sedan as she drove down a narrow road toward the ferry wharf in the fishing village.

Witnesses have said that Torgerson’s car appeared to accelerate even after she struck a parked vehicle and then hit a pedestrian and building just in front of the wharf. Police said her car continued forward and struck six more cars parked on the wharf before hitting members of the Gold family who were walking toward the end of the pier to wait for a ferry to Monhegan Island.

Gold’s husband, Howard Gold, was in the family’s van when the accident occurred and was not harmed.

Howard Gold is a doctor at Beth Israel Deaconess Medical Center in Boston, where Allison Gold is a nurse.
