FARMINGTON, N.H. — Three children under the age of 6 who walked to their local police station in Farmington, N.H., looking for a ride to school are in foster care and their mother was arrested on child endangerment charges.

Police said 26-year-old Katarina Short was charged after leaving her children unattended for about two hours.

The children showed up at the station at about 7:30 a.m. Tuesday. Lt. Jay Drury said the oldest, a 5-year-old boy, dressed his 4-year-old brother and 1-year-old sister in boots and jackets appropriate for the cold weather before heading out.

Short arrived at the station an hour later after receiving several voicemails from police. She said she left the children with a baby sitter so she could run an errand. Police determined no baby sitter had been called.
