David Marchan was 18 when he was last seen in Des Moines, Iowa on January 1, 2001. He’s classified as endangered missing. At the time he disappeared he was described as a Hispanic male with brown hair and brown eyes, about 5 feet 5 inches to 5 feet 8 inches tall and 160 to 180 pounds. Distinctive features include tattoos of hands on his chest, the phrase En memoria de mi jefecito, the word dice, and a pierced left ear; he commonly wore Docker-style pants and button-down collared shirts.

Reports say David may have fled to the Los Angeles area after allegedly witnessing a murder in Des Moines and fearing for his safety. It is not clear whether he told police anything about that alleged crime before he disappeared. The Des Moines Police Department and the California Department of Justice Missing and Unidentified Persons Unit are involved in the inquiry, and his family has used social media and missing-persons sites to keep his case in the public eye.

Does anyone who knew David, saw him after January 1, 2001, or has information about the alleged murder he might have witnessed contact the Des Moines Police Department or the California DOJ?
