Police say a 54-year-old White Plains woman drove onto the sidewalk, struck O'Rourke and then smashed into a house.

Yonkers Police and the Westchester district attorney tell CBS New York an extensive investigation, including toxicology, did not turn up sufficient evidence to support criminal charges.

O'Rourke's family says it is difficult to accept the driver won't be prosecuted.
