Missing Persons: Sage and Isaac Cook

---

Video Transcript

Mollie Halpern: The FBI is asking for tips to help find these two young brothers, Sage and Isaac Cook, who have been missing since the summer.

The boys flew from Seattle to the Los Angeles International Airport to visit their mother and toddler half-brother on August 28—that’s the last time they were seen.

Case Agent Caryn Highley says the father has full custody of Sage and Isaac.

Caryn Highley: The children’s father, he is doing everything he can to find his two kids. You can tell he is devastated.

Halpern: Investigators say there were no signs of suitcases at the California home of Sage and Isaac’s mother, Faye Ku.

In 2013, Ku tried to take the boys to Taiwan without their father’s permission, but law enforcement stopped her before they boarded the plane.

Highley: The FBI is concerned because of her previous attempt to take the kids to Taiwan, so right now we’re just devoting all of our resources to finding her and the children.

Halpern: Take a look at 15-year-old Sage and his 9-year-old brother to see if you recognize them.

Highley: Sage—he is the older brother—he is quiet, kind of introverted. He loves to write, loves to journal, is very protective of his younger brother Isaac. And then Isaac—he is just fun-loving little kid, very bubbly personality.

Halpern: In addition to Taiwan, Ku has ties to several western states, Canada, and Mexico.

Highley: We don’t know if they’re okay and really we need to make sure that they are safe.

Halpern: If you have information on the boys' whereabouts, contact your local FBI office or nearest American Embassy or Consulate. With Wanted by the FBI, I’m Mollie Halpern of the Bureau.
