Melissa Fu was 12 when she and her mother, Amber Aiaz, vanished from their Irvine apartment near Michelson Drive and University Drive on November 22, 2019. Amber’s husband, Cheng Zhang, reported that two people described as of Chinese descent knocked at the door; when Zhang answered he was rendered unconscious by an unknown substance. On waking he found Amber and Melissa gone and bloodstains in the apartment, while both women’s passports and personal belongings remained behind.

Investigators have treated the disappearances as suspicious and have explored a possible financial motive tied to Amber’s claims of wealth, which later proved false. Witnesses reported seeing a male and female at the scene who may have been driving a black Cadillac.

If anyone has information about Melissa, Amber, the two people seen at the door, or a black Cadillac in the area on November 22, 2019, please share what is known.
