I like the concept very much, however the whole report is very weak and needs alot of work.
-the containment should be more descriptive, the people who enter the cell should be terminated and autopsied (only autopsied if they were changed)
-I dont think the threat of suspension would do much, they should probably be threatened with termination, your sentences about the language abilities need to be fleshed out.
-Also i dont think a missionary group would be able to contact the organization… they are kinda secretive about what they do, maybe if the group went missing and was found by the native gov't which then led to an agent or the org finding out
these are just some suggestions, you dont have to take any of them. interesting idea though.
