From Mosnews.com, entitled "Russia's Biggest Spammer Brutally Murdered"):

Vardan Kushnir, notorious for sending spam to each and every citizen of Russia who appeared to have an e-mail, was found dead in his Moscow apartment on Sunday, Interfax reported Monday. He died after suffering repeated blows to the head.

The shape of the indentations in the victim's head seem to match that of the bloody Motorola VoiceSurfer found near the body. (Writer's embellishment)
