Welcome to Harry Potter Answers. What would you like to know?

Voldemort created more then one horcrux, so when Voldemort tried to kill Harry, the Killing Curse backfired on Voldemort and his soul had become so unstable that a fragment broke off and attached itself to Harry's soul, turning Harry into an accidental Horcrux. This suggests that as one's soul becomes more unstable, significant trauma (such as a rebounded Killing Curse) may cause part of the soul to break off without having the need to cast the spell for Horcrux creation. About the murder, it is unspecified.But it must have been Harry's parents, because they where murded right before Harry became a Horcrux.
