PERM, Russia (Reuters) - Russian investigators blamed management negligence for a blaze at a provincial nightclub on Sunday, December 6, 2009 that killed 110 people as relatives gathered at a central morgue on Sunday to identify the charred remains of loved ones. Eyewitnesses said sparks from fireworks set fire to wicker coverings on the walls and ceiling of the packed club on Friday, and that a stampede broke out as more than 200 guests rushed toward a single narrow exit. An initial investigation found the club was not equipped with automatic fire extinguishers and that fireworks should not have been used there, Marina Zabbarova, head of the Russian Prosecutor General's Investigative Committee for Perm region, said.
