They do indeed have a problem with killing off their bad guys way too quickly, David Robert Jones in season 1 now Newton
"In season one the Fringe team has several encounters with a man named David Robert Jones. In the second season they fight a visitor from the alternate universe named Thomas Jerome Newton. "David Robert Jones" is the real name of the singer/actor David Bowie and "Thomas Jerome Newton" is the name of the character he plays in the movie "The Man Who Fell to Earth".
Why him? It would be awesome if he did a cameo in Fringe
