Khanh Ngoc Trinh was 25 when he was last seen on January 23, 1995, in Lake Forest, California. He had been in the United States only four days at the time. Witnesses placed him later that day in the Oceanside area but he made no further contact with family or friends.

Khanh is described as Asian, with black hair and brown eyes, 5 feet 4 inches tall and about 125 pounds. His case is classified as endangered missing and DNA is available for identification. The Santa Ana Police Department is listed as investigating, but there are few publicly reported details about his movements or contacts after that January day.

If anyone knew Khanh, saw him in late January 1995, or has information about his arrival in California, please contact investigators with any tips.
