Going around OLD patch notes for fun and see this..

Death Defied: (Passive) When Karthus dies, he can continue to cast spells for 10 seconds after death. If he kills a champion in this time he respawns instantly at base.

So you were unkillable when this was still possible (be4 they updated the sec you killed him that showed the kill and for kogmaw too.. It was anoying be4 the update when you had to wait to be shown who killed him)
