OOP: Petunia a band witch.

 I was reading OOP for a second time and it hit me. Petunia knows so 
much about the wizarding world and demintors, that she has to be a 
witch. Before you start disputing this theroy, hear me out. She was 
so frightened when she was talking about the dementors it just seems 
so obvious to me. She IS/WAS a witch who commited a crime, went to 
azkaban and was forced not to come back to the wizarding world.

I know this is kinda a one liner but tell me what y'all think
