A mother is facing serious charges after her 3-year-old son was discovered wandering the streets of Grandview nearly naked and crying on Tuesday afternoon. When no one answered, they returned shortly thereafter and were met by a woman described as the boy’s mother. The woman reportedly admitted that she had fallen asleep in the early morning hours and had left her two young children — including the 1-year-old sibling — alone in the house for more than nine hours. MOM ARRESTED AND PLACED IN JAILAuthorities say the 36-year-old mother was arrested on charges of Second Degree Abandonment of a Dependent Person and booked into Yakima County jail. The mother's children were taken into custody by Child Protective Services as authorities continue their investigation.
