PHOENIX -- The FBI is asking for the public's help identifying a man who may have information about the sexual exploitation of a child.
The individual of interest, called John Doe 21, first came to the FBI's attention after a series of photographs surfaced on the Internet, according to a news release. Officials said the man appears to be watching a child approximately 10 years old pose for pornographic pictures.
Enhancement of the background of one of the photographs identified what appears to be a child's drinking cup from the QuikTrip chain of gas stations.
This image led investigators to believe that the photographs were likely taken prior to November 2005 in one of the following 13 U.S. cities where QuikTrip stores are located: Phoenix; Tucson, Ariz.; Atlanta; Charlotte, N.C.; Dallas/Fort Worth, Texas; Des Moines, Iowa; Omaha, Neb.; Greenville/Spartanburg, S.C.; Kansas City, Mo.; Springfield, Mo.; St. Louis; Wichita, Kan.; and Tulsa, Okla.
A baseball cap displaying what could be the logo of a local sports team, as well as a partial image of what appears to be a telephone book, may provide information regarding the location of the endangered child.
The man is being sought for questioning. Officials believe that he may possess valuable information regarding the identities of both a victim and a producer of child pornography.
His identity and current whereabouts are unknown. He is described as a white male between the ages of 55 and 65, with brown eyes, gray hair and a full beard and mustache.
