Pippin:
The swishing sound is clearly separated from the  effects of the 
AK -- the flash of light and the sound of Cedric falling. Could it be
the approach of the real killer? I've said before, it's quite a feat that
clumsy Peter, who doesn't trust his conjured ropes but has to
check them, manages to put his bundle aside and draw his wand before Cedric, who 
already has his wand out, can do an expelliarmus. And so convenient that Harry had his 
eyes closed. 

Here's a little canon to back it up -- the arrival of the other Death Eaters at the graveyard.
"The air was suddenly full of the swishing of cloaks." -- GoF ch 33

stubbornly convinced that JKR's confirmation that it was Wormtail using Voldemort's wand 
means that there are two characters using the alias Wormtail.
