I found him. I actually found him. He's near the school and they're planning an attack very soon. The Death Eaters will just cause random mayhem but he's going after McGonagall. Don't have time to tell you how I know this. Am going after him.
He is the last horcrux of course, but Nagini is the second last. Nagini is in the old Riddle manor with some other Death Eaters, but I think most will be with him. What I need you to do is destroy the horcrux while I go after him. I've left a porkey outside the school gates - don't want to give too many details away but you'll recognise it - BUT you're not to go alone. Take anyone with you who will be useful and can be trusted but DON'T GO ALONE.
This is it. I have to go now. I'm going to kill Voldemort. I'm going to do it. And if I don't, at least I won't be here to remember. If I don't come back, well, you know. But thank you for being a friend, while I was here.
