Ezra Lok Lui was 2 years old when he was last seen on November 13, 1999, in Irvine, California. At the time he was under the sole custody of his father, Samuel Lui, after legal action against his mother, Terumi Kakiuchi, for spousal abuse. Kakiuchi was granted an overnight visit on the day Ezra disappeared and did not return him.

Kakiuchi is also known to use the alias Satori Kawamura. It is believed she took Ezra to Japan; Japanese authorities later allowed Samuel limited contact, but Samuel has not seen Ezra since 2004. Ezra is of Chinese and Japanese descent and was believed to be living in Osaka with his mother. Age-progressed images have been circulated over the years but have not produced a confirmed sighting.

The Los Angeles District Attorney’s Office continues to handle the family abduction case and asks anyone with information to come forward. Did anyone in Irvine or Osaka have contact with Ezra or his mother around 1999–2004?
