Police say a couple faces charges after leaving their 8-month-old son in his playpen at an acquaintance's apartment while they walked to a convenience store.

Anne Arundel County police say a person who let the family stay with him called police around 11:30 p.m. Sunday after coming home to find the infant alone in an unlocked apartment in Brooklyn Park.

Police say the parents returned and told officers they thought the sleeping baby would be fine while they walked to a Royal Farms store a mile away.

Police charged 23-year-old Cody Wolford and 22-year-old Christina Justice, both of no fixed address, with neglect of a minor and confined unattended child.

Police say the baby is in his grandparents' custody. Neither the parents nor an attorney could be reached for comment.
