TIJUANA, Mexico (AP) — Mexican police have found the three grandchildren of a California congressman in the border city of Tijuana nearly four years after they were allegedly abducted by their mother.

Tijuana police say they located the 11-year-old boy and 9-year-old twin boys and arrested Jennifer Dejongh. Police identified the mother by her maiden name, Jennifer Lopez. The boys are the grandsons of Republican U.S. Rep. Gary Miller.
