Chen Mason, an Asian male child born May 25, 2016, was four years old when he was last seen on August 1, 2020, in Santa Clara, California. His physical characteristics at that time included black hair, brown eyes, an estimated height of approximately 3 feet 3 inches, and weight around 30 pounds. A distinctive physical feature noted was a “missing tip on left ear”.
Circumstances surrounding his disappearance indicate that he was allegedly abducted by his non‑custodial mother, Jin Zhao. A felony warrant was issued for Jin Zhao on October 7, 2020. Authorities believe they may have traveled to China.
The case is recorded in several missing‑persons databases. The National Center for Missing & Exploited Children lists Mason Chen under case number 1402908, noting that although his official missing‑since date is August 3, 2020, he was last seen on August 1, 2020. The NamUs database confirms his date of last contact as August 1, 2020, and includes details such as his height, weight, ethnicity, and the missing‑ear feature.
Online case summaries similarly corroborate these key facts. For example, a profile on missingpeopleinamerica.org reports that Mason Chen was last seen August 1, 2020 in Santa Clara, and that his mother, Jin Zhao, is believed to have abducted him and may have traveled to China, following a felony warrant issued on October 7, 2020. Another summary on forthelost.org includes a photo and vital statistics, reiterating that he was four at the time, was abducted by Jin Zhao, and that the warrant issuance and potential international travel remain part of the case file.
To this day, Mason Chen’s whereabouts remain unknown. The Union City Police Department is the investigating agency; they can be reached at 510‑471‑1365.
No additional information about his clothing, exact location within Santa Clara, or other identifying details were located in the sources reviewed.
