Federal authorities are using clues from photos and video footage to hunt down a man they say has sexually exploited numerous children.
An FBI statement released on Wednesday said that an unknown man who has been dubbed John Doe, 28, was seen captured on tape participating in sexual activities with a young child, the Chicago Tribune reported. The National Center for Missing and Exploited Children recorded the images and video in November 2012.
Now, law enforcement officials are using the photos - expanded and enhanced for more detailed investigation - and footage to track down John Doe.
Investigators from the FBI and the National Center for Missing and Exploited Children told the Tribune they'd managed to get a clear photo of John Doe's face, and will use certain clues to help identify the man.
Federal authorities have zeroed in on a number of details specifically, including a unique emblem on an article of clothing, and pictures posted inside the area where Doe carried out the lewd acts.
One video shows the victim and suspect inside a room with a blue sofa chair and a picture hanging on the wall, the Tribune reported.
Authorities have described the man as white, potentially in his 30s or 40s, with a receding hairline and wire-framed glasses, according to the Tribune. In the video, the suspect is wearing a burgundy t-shirt with what looks like the image of a shark on the left hand side.
It's unclear at this point where the man is located, as no details found in the video or images connect John Doe to any state or specific area.
Police are urging anyone with information on this man's identity or whereabouts to send tips to https://tips.fbi.gov, or to call 1-800-CALL-FBI (1-800-225-5324).
