UPDATE: FBI agents have been using metal detectors outside the home of a 10-month-old Missouri girl who disappeared earlier this week.

Kansas City police Capt. Steve Young says federal agents have been running metal detector wands around the family’s yard Friday. He said the search wasn’t prompted by a tip, but was being done as part of a thorough sweep of the house where the baby, Lisa Irwin, was last reported seen late Monday.

Earlier Friday, the FBI also had crews searching a landfill in Shawnee, Kan., about 25 miles west of the family’s home in Kansas City.

The baby’s parents say she was abducted from her crib late Monday or early Tuesday. Police say so far no evidence has been found in the disappearance, and no suspects have been named.
