A Coral Gables, Fla., woman remained in critical condition in a Boston hospital Monday after she was struck by a car while crossing Upper Main street in Edgartown on foot on Saturday night.

Patricia Guarch, 22, who is working at the Vineyard Arts Project on Upper Main street for the summer, was crossing the street on her way to get ice cream, just after 10 p.m. Saturday, when she was struck by a 2010 Subaru Outback. The driver of the car was Robert Franklin, 85, of Vineyard Haven.

Ms. Guarch was transported to the Martha’s Vineyard Hospital with multiple injuries and later airlifted to Beth Israel Deaconess Medical Center, Edgartown police said.

Police said yesterday that Mr. Franklin was cited at the scene for speed greater than reasonable, crosswalk violation and negligent operation. Further charges are pending the results of an investigation, police said.

The Massachusetts state police accident reconstruction team arrived on the scene on Sunday; the accident remains under investigation by Edgartown and state police.

Police, fire, ambulance and rescue personnel all responded to the scene.
