The driver accused of killing Hawaii Pacific University student Mariah Danforth-Moore in a hit-and-run collision in front of the school's Hawaii Loa campus pleaded guilty in state court Monday to leaving the scene of a fatal traffic accident. 31-year-old Dominic Franklyn faces a maximum 10-year prison term when he's sentenced in April.  His attorney says Franklyn will ask the judge to give him the opportunity to avoid conviction by deferring his guilty plea.  Nineteen-year-old Danforth-Moore was in a crosswalk on Kamehameha Highway November 20, 2011, when a car struck her and the driver continued without stopping.  She was taken to a nearby hospital and died there a short time later.  Franklyn turned himself in two days later.
