A Fremont woman hit by a car Tuesday while walking in a crosswalk on Civic Center Drive remains in critical condition.

Manchi Wong, 59, suffered a major head injury after being struck around 5 p.m. in the 38900 block of Civic Center Drive, said Sgt. Mark Dang.

Wongwas unresponsive at the scene, police said, and taken to Eden Hospital. She remained hospitalized and unconscious on Wednesday morning, Dang said.

An early investigation indicated 19-year-old Nathaniel Fedalizo, of San Jose, was driving a sedan north on Civic Center Drive and that Wong was struck while walking west across the road in the crosswalk, police said.

Fedalizo was uninjured, and police said drugs or alcohol do no appear to be a factor.

As of Wednesday no charges had been filed against him, Dang said.
