Quy Tran was hit while crossing Senter Road at Independence Drive at about 8 a.m., Sgt. Mike Sullivan said.
The driver got out after the crash and allegedly dragged her off the roadway, but then drove away, according to Sullivan.
Tran was taken to Santa Clara Valley Medical Center, where she died.
The suspect is described as an Asian man between 25 and 35 years old with a thin muscular build and short black hair. He was in a green sedan, possibly a Honda, Sullivan said.
