A reward offer, a mother's public statement and the sharing of a personal letter has stoked the fire in the search of the three Marokopa children. Ember, Maverik and Jayda Phillips were last seen with their father Tom Phillips in the western Waikato community more than two years ago. Police say they are working through more than forty reports of credible sightings as the deadline for the $80,000 reward ends on Tuesday. Detective Inspector Andrew Saunders spoke to Ingrid Hipkiss.
