From Deliberate Murder's Facebook page:

Sergey 'evil' Orekhov leaves deliberate murder. Reason is simple: after USA and Prague 102 ain't sure we've got enough money for Dreamhack Winter 2013. "102".evil played Dreamhack Summer 2012, Dreamhack Winter 2012, Renaissance, Adroits LAN, QuakeCon 2013 and hell of a lot smaller tourneys. We don't know if he's going to be a "loner", or he's got new sponsors. Anyway, good luck to him!
