THE BRONX - The mother of a Bronx woman who was killed two years ago in an unsolved hit-and-run says she won't rest until her daughter's killer is brought to justice.

Police say Yvette Diaz, 28, was killed by someone driving a black SUV after dropping off the car she used as a designated driver for her friends.

Her mother, Ruth Santos, says more needs to be done to prevent fatal hit-and-runs like the one that claimed her daughter's life.
