An 8-year-old girl was terminally injured Monday evening after an assumed drunken driver struck the car she was wandering in, police said.

The accident happened around 8:19 p.m. on eastbound Woodside Road near Santa Clara Avenue, Redwood City police Officer Brad Johnson said.

The victim, Redwood City resident Sydney Ng, her 10-year-old sister and her mother had just dragged onto Woodside Road from Santa Clara Avenue when their gold Nissan Maxima was broadsided by 45-year-old Redwood City resident Richard Tom's silver Mercedes Benz, Johnson said.
