Does anyone know where did Voldemort's wand come from when Wormtail 
had it in the cemetary in GF? If Voldemort was so weak after being 
destroyed from trying to kill Harry, he could certainly not have 
hidden or moved it himself. If a Death Eater got there first before 
Hagrid, he could have taken the wand and tried to kill Harry, but it 
does not appear to have happened.....
