When Voldie died at Harry's house - he must have dropped his wand there! And then when he reappears at book 4 he pulled out the wand out of his robe.
Did one of his loyal followers got to the house and got the wand? Wasn't Hagrid the one who got there first? Why didn't he take it?
Or maybe when the wizard is powerful, the wand is carried with him regardless if he dies or not?
