Why did Voldemort go to Lily and James House?
Pettigrew betrayed the Potters and gave up their location to Lord Voldemort. Having been told half of the prophecy by Severus Snape, Voldemort came to believe his mortal enemy to be Harry Potter. He travelled to the Potters’ home in Godric’s Hollow and murdered James and Lily Potter, whom died protecting infant Harry.
