( CNN ) -- A federal court jury in Florida convicted seven people of participating in a global child pornography trafficking enterprise , according to the Department of Justice . Jurors convicted the seven Wednesday of multiple counts of child exploitation , pornography and obstruction of justice . Members of the organization used Internet news groups to swap and share `` illegal images and videos depicting prepubescent children , including toddlers , engaged in various sexual and sadistic acts , '' prosecutors said . An indictment filed in the case detailed interactions between group members as they swapped and commented on images . `` My thanks to you and all the others that together make this the greatest group of pedos to ever gather in one place , '' Freeman wrote in response to one posting , according to the indictment . And a posting from Castleman , cited in the indictment , read , `` Thanks to all for the wonderful material that has been posted . '' An Australian constable who infiltrated the group in August 2006 was among 50 witnesses testifying at trial . He told the jury that the group traded more than 400,000 images and videos of child sexual abuse before being dismantled by law enforcement , according to the Justice Department statement . Each defendant faces a sentence of 20 years to life in prison , fines and the possibility of supervised release for the rest of their lives , authorities said . The seven will be sentenced April 14 . During the six-day trial , evidence showed the seven participated in what prosecutors called a `` well-organized criminal enterprise whose purpose was to proliferate child sex abuse images to its membership during a two-year period . '' `` This was a wide-scale , high-volume , international trafficking enterprise that used sophisticated computer encryption technology and file-sharing techniques , '' Matthew Friedrich , acting assistant attorney general , said in the statement . The seven defendants were James Freeman of Santa Rosa Beach , Florida ; Gary Lakey of Anderson , Indiana ; Marvin Lambert of Indianapolis , Indiana ; Neville McGarity of Medina , Texas ; Warren Mumpower of Spokane , Washington ; Daniel Castleman of Lubbock , Texas ; and Ronald White of Burlington , North Carolina , according to the Department of Justice .
