IRVINE, Calif. (KABC) -- The FBI and police are asking for the public's help in finding an Irvine mother and her daughter who went missing last year.
Irvine police are investigating the case as a possible kidnapping and the FBI says it is offering a $10,000 reward for information leading to the whereabouts of 35-year-old Amber Aiaz and her 13-year-old daughter Melissa Fu.
The mother and daughter were last seen on Nov. 22, 2019 at their Irvine home in the area of Michelson and University, according to police.
