WICHITA, Kan. (AP) — A Wichita man will soon learn his punishment for harboring a Chinese teenage girl who was working illegally at his restaurant.

A notation Tuesday in U.S. District Court has moved up the sentencing for 33-year-old Yong “Tony” Lin to April 28. He has pleaded guilty to harboring an immigrant who was unlawfully in the United States.

His 29-year-old wife, Zhuo Mei “Mandy” Weng, has pleaded guilty to hiding the crime. She will be sentenced on the same date before U.S. District Judge J. Thomas Marten.

Both had originally been set for sentencing May 7.

The case stems from a tip that a minor teenager being housed with other employees at an apartment was working at Lin’s World Buffet Grill.
