By the age of sixteen, Tom Riddle had accomplished the incredibly 
complex and advanced magic of the diary, containing his memories and 
self. I've no doubt he had mastered by that time all the 
Unforgivables, including AK.
I'd always thought that Tom had done this murder as a kind of rite of 
passage on graduating from Hogwarts. Is there any cannon evidence 
against this?
