Taking the witness stand Thursday, Francesca Palza took a courtroom on a painful journey back in time to the day Ashley Valdes lost her life. She described how her 11-year-old friend lay on the grass after she was fatally struck in a hit-and-run on SW 80th Street three years ago. Closing arguments were underway Thursday in the trial of Harvey Carlos Abraham, who is charged with vehicular manslaughter in Valdes' death. Miami-Dade Police Det. Oscar Perez spoke about the case.
