Seventeen-year-old Yincan Dong, also known as Thomas, was last seen after traveling from Park City, Kansas, to Queens, New York; he flew to New York on October 23, 2023. He is six feet one inch tall, about 150 pounds, with black hair and brown eyes. Prior to his disappearance he served as Director of the K&Y Project, an organization that advocates for the rights of undocumented first-generation immigrants in New York, and had left Kansas hoping for a brighter future after experiencing bullying.

The Park City Police Department is leading the investigation and has coordinated with New York law enforcement. Investigators have interviewed people who knew him, reviewed surveillance footage, and examined his digital and financial records. Vigils and rallies have been held in both Kansas and New York, and advocacy groups have helped distribute information about his disappearance.

What information might help establish Yincan’s movements in Queens on and after October 23, 2023?
