Daniel Yuen was 16 when he went missing from Running Springs, California, on February 8, 2004. He had been sent to the Cedu School about ten days earlier for help with depression and emotional problems, but family members say he was unhappy there and had told them he planned to run away because he feared other students.

On the morning he disappeared Daniel left the school saying he was going to buy cigarettes. He took no belongings or identification and never returned. There were several reported sightings afterward, including claims he was seen panhandling and acting oddly near a waterfall in San Diego and reports placing him in Blythe. In 2018 a voicemail was received claiming Daniel was still in the area and did not want to be found, but it yielded no concrete leads.

Daniel’s case is classified as endangered and remains unsolved. If anyone has information about his whereabouts from February 2004 onward, please contact the appropriate investigators.
