Kansas City, Kan. ? A 38-year-old elementary school teacher and coach has admitted posing as a young woman on Facebook and talking boys into sending him nude pictures of themselves.

Michael Cowley of Shawnee pleaded guilty Wednesday in federal court to one count of producing child pornography.

He acknowledged that he posed as a 19-year-old woman on the social networking site so young boys would send photos of themselves engaging in sexual activities.
