There was no suggestion of foul play in the death of the reformer from St Petersburg, a city that has become known as the "mafia capital" of Russia. It was a second heart attack, to silence those who accused Sobchak of feigning heart disease to escape corruption charges.

From The Independent: a newspaper you can believe. Will that be all or will you be introducing more such topics?

Yes, they are mostly correct, however the obituary was posted the day after his death and later, on April 12th it was obviously suggestions of foul play. Read the link in my previous post.
