The family of a missing 22-year-old college student from Syosset is searching for any information about their son.

Richard Ng was seen leaving a Columbia University dorm around 10 p.m. Sunday, wearing dungarees, a dark jacket and a backpack. Investigators believe he had just finished a lab with a friend, and say he may have been seen later that night in the area of West 72nd and Broadway.

Ng?s parents, Sui and Kin, says they last spoke with Richard two weeks ago when his mother dropped food off at his dorm. Anyone with information is urged to call the New York City Detective Squad at 212-678-1351.
