PORTLAND, Ore. - The FBI calls him John Doe 27, although he may call himself "Jimmy" in one of the videos.
Investigators don't know who he is - or where he is.
But photos and videos that show him sexually abusing a child are still making the rounds on the Internet, prompting a nationwide call for the public's help locating John Doe 27.
The suspect appears to be a white man, possibly in his 40s or 50s, with dark hair and dark eyes, the FBI said.
Anyone with information on the suspect should submit a tip online or call the FBI's toll-free tip line at 1-800-CALL-FBI.
In April, the National Center for Missing and Exploited Children first located the images and videos of John Doe 27 as he was engaging in sexually explicit activities with a child, the FBI said.
Investigators enhanced a number of photos depicting John Doe 27, and they believe there are several clues which may assist with the identification of the subject, FBI said:
For example, the images depict:
- John Doe 27 and the victim inside a residence with a distinctive plaid chair
- Male pattern baldness on the back of the subject's head
- A ring on the subject's right ring finger.
In the audio on the video, the individual may have referred to himself as "Jimmy."
