JACKSONVILLE, Fla. - The FBI is seeking the public's help in identifying a man suspected of sexually exploiting a child.
Initial images and video of the man, known only as John Doe 28, engaging in sexually explicit activities with a child were first recorded by the National Center for Missing and Exploited Children in November 2012.
Investigators for the center and the FBI said they have enhanced images depicting the man and believe they contain several clues that may help with identifying him.
The video shows the man and victim inside a home with what appears to be a blue sofa chair and a picture hanging on a wall in the background. The man is wearing wire-framed glasses and a burgundy T-shirt with what appears to be a shark logo on his left side.
There are no specific details linking the man to a particular state or region of the U.S., investigators said.
They said the man appears to be white, possibly in his 30s or 40s, with a receding hairline.
Anyone with information about his identity should submit a tip online or call the FBI's toll free tip line at 800-CALL-FBI (225-5324).
