FBI wants man who may have info on child sexual assault victim

The FBI is asking for help finding a man it says "may have critical information pertaining to the identity of a child victim in an ongoing sexual exploitation investigation."

Special agents are calling him John Doe 37 and say the National Center for Missing and Exploited Children first sent videos of him with a child in June, 2014.

However, "The EXIF data embedded within the video files indicated that the files were produced in April of 2012. Audio from the animated film 'The Land Before Time' can be heard in the background of the videos."

John Doe 37 is wanted as part of the FBI's Operation Rescue Me, which focuses on utilizing clues obtained through in-depth image analysis to identify the child victims depicted in child exploitation material, and also its Endangered Child Alert Program initiative, which seeks national and international media exposure of unknown adults (referred to as John/Jane Does) who show their faces and/or other distinguishing characteristics in association with child pornography images.

John Doe 37 is described as having brown hair and wearing dark-framed glasses.

Anyone with information is urged to call the FBI's toll-free tip line at 1-800-CALL-FBI (225-5324) or click here to submit a tip online.
