(Cincinnati) -- They don't know if he's from the TriState, but the FBI is releasing images of a man they say is wanted for sexually exploiting a child.  The screen grabs are being shown nationwide, in hopes someone can identify him.

In November of 2012, the National Center for Missing and Exploited Children first obtained the images of the man, now referred to as John Doe 28, while he was "engaging in sexually explicit activities with a child". 

The FBI says he's sitting in front of a blue sofa chair, and there's a picture hanging on the wall .  The man is wearing wire rim glasses and has a t-shirt with a shark logo on the left.  They estimate he's in his 30s or 40s.

Investigators don't know where in the country John Doe 28 is from, so, FBI offices across the country are spreading the image, in hopes someone will recognize him, and contact them at 1-800-CALL-FBI, or online
