(CHICAGO) The FBI is asking for the public’s help identifying a man wanted in an ongoing child sex exploitation investigation.

John Doe 37 came to the attention of the National Center for Missing and Exploited Children in videos in June 2014, according to the FBI.

The data in the video files indicates they were produced in April 2012, and audio from the animated film “The Land Before Time” can be heard in the background, according to the FBI.

He is described as a white man with brown hair and wearing dark-framed glasses.

Anyone with information about his identity should call their local FBI office.
