Diana Judith Portillo was twelve when she disappeared from her Denver home in the summer of 2010. Authorities believe she was taken on July 23, 2010, by her non-custodial father, Walter Adonay Pineda, who was 39 at the time; a felony kidnapping warrant for Walter was issued July 29, 2010.

Diana is described as Hispanic with brown hair and brown eyes and a distinctive birthmark on her right arm near the elbow. Investigators believe she and her father left the country, possibly traveling to El Salvador, Walter Pineda’s home country. It is thought Diana may be using the name Portillo Pineda and her father an alias Pineda Ochoa.

The Denver Police Department still holds the outstanding warrant, and the National Center for Missing and Exploited Children has released age-progressed images. Does anyone have information about Diana’s whereabouts, her life under the name Portillo Pineda, or sightings after July 2010?
