BANGOR, Maine (NEWS CENTER) — Bangor Police are asking for the public's help in finding a mother and her two children who were last seen Sunday.

Police say 26-year-old Liza Parker, her 5-year-old son Mason Worcester and her 1 year-old daughter, Tiaona Robinson were supposed to be at a scheduled appointment and never showed. Police say that is uncharacteristic for Parker not to show.
