Washington boys found in Mexico after mother allegedly abducts them

The FBI says two brothers missing from Bellevue since August have been found in safe condition in Mexico.

FBI officials said in a news release that 15-year-old Sage Cook and 9-year-old Isaac Cook were located by authorities in Mexico's Sinaloa state.

They reportedly returned to Washington Friday with their father, David Cook, and stepmother, Helen Cook, after they were reunited in Mexico earlier in the day.

The boys were last seen in California at Los Angeles International Airport to have a supervised visit with their biological mother, Faye Ku, on Aug. 28.

The FBI says Ku has been taken into federal custody.

Legal documents show Ku, who hasn't had custody of the boys since her divorce from their father in 2009, attempted to leave the country with Sage and Isaac in 2013.
