Kao was born and raised in Hacienda Heights, California, where he later graduated from Glen A. Wilson High School.
However, during one of the in-class previews of the show, Kao was falsely arrested for attempted murder and assault with a deadly weapon.
Kao was later released in the absence and lack of probable cause, giving him enough time to make it before the closing night of the show.
After being forced to contemplate his life inside jail, Kao realized he wanted to pursue acting as a profession.
[2] In 2012, Kao made his television acting debut in the AMC post-apocalyptic horror series The Walking Dead.
