Trelawneys first true prediction.

My theory is simple.  There are two questions that seem to anwser 
themselves.  First is about Trelawney's first true prediction, and 
second is how did Voldemort know to go after Harry in particular.  It 
is obvious in many instances that Voldemort wanted Harry, not 
necessarily his parents.  My theory is that Trelawney predicted the 
fall of Voldemort in connection to Harry Potter, and she did it in 
front of a death eater.
