A 16-year-old girl who was practicing how to parallel park struck and killed her mother, authorities said.
No charges will be filed, Robert A. Honecker Jr., a Monmouth County prosecutor, said Friday. "This is going down as a tragic accident," he said.
Ryta Z. Deriso was watching her daughter, who had a valid learner's permit, when the accident happened Thursday.
The two had set up cones on a quiet street near their home, Honecker said. Neighbors told investigators the girl was backing up when she pressed the accelerator, causing the car to jump onto the curb and hit her mother, he said.
Deriso, 44, of Marlboro, was pronounced dead later Thursday, Honecker said.
