Peishuan Fan, 48, of Old Brookville, New York, was last seen the night of March 30, 2025, at about 10:30 p.m. at his Maria Drive home alongside his wife, 44-year-old JuanJuan Zwang. Their disappearance was reported to the Nassau County Police Department on March 31 after both failed to contact their two sons, aged 12 and 20.

Fan is described as an Asian male, about 5 feet 2 inches tall, 135 pounds, with brown eyes and black hair. The couple’s Bentley SUV and their home, registered in Zwang’s name, were reportedly left untouched, which authorities called unusual for a voluntary departure. Neighbors described the family as friendly and expressed shock; investigators are exploring multiple theories, including foul play or a voluntary disappearance, but have not released detailed findings.

No significant leads have been announced. Anyone with information is asked to contact the Nassau County Missing Persons Squad at 516-573-7347 or dial 911. Did anyone in Old Brookville see the couple on the night of March 30?
