Who did Voldemort Possess?

(A few days ago a wrote a post about Voldemort's power to possess. I have a 
nasty habit of writting a post before I get all my thoughts collected and I 
don't think it was very clear. So I'm rewritting it. At least for my own 
peace of mind ^-^) 

"Only one power remained to me. I could possess the bodies of others." 

This quote has really got me thinking. He says the power *remained* to him. 
Well, who did he possess? And why? Why not just use the Imperius curse to 
control someone? The only reason I can figure is to do something vicariously 
through that person-but Who and What? And will he use this power again? Any 
ideas?
