Dung:
The only mention I remember is at the beginning of HBP ch6 (p103 UK) 
when Lupin says:
"And they've found Igor Karkaroff's body in a shack up north. The Dark 
Mark had been set over it - well, frankly, I'm surprised he stayed 
alive for even a year after deserting the Death Eaters; Sirius's 
brother Regulus only managed a few days as far as I can remember."
