Authorities are searching for four foster children who were discovered missing from their beds during head count at a private foster care home near Tampa.

In a news release, Hillsborough County Sheriff's spokeswoman Debbie Carter said officials at A Kids Place believe the girls — ages 13, 11, 10 and 4 — climbed out a window between 10 p.m. Thursday and 2 a.m. Friday. Then, they either scaled a fence or were able to squeeze through an opening at the gate.

Carter says 4-year-old Allison Nelson, 10-year-old Anabella Gonzalez and 11-year-old Heavenlynn Gonzalez are sisters. They are with 13-year-old Ashlyn Smith.

Officials at the home didn't know what the girls were wearing when they went missing. They have no medical issues or disabilities and don't take any medication.
