MOSCOW (AFP) - A 30-year-old Russian man apparently suffering from unrequited love killed five colleagues on a shooting spree in his Moscow office after declaring his hatred for life. The man is believed to have posted an online manifesto in which he proclaimed his “hatred for humankind as a species” hours before the killing spree, prompting comparisons with Norweigian killer Anders Breivik. Dmitry Vinogradov, 30, opened fire at the offices of the drugs company in northeast Moscow, killing five of his colleagues and wounding another two, the Investigative Committee said. “On the morning of November 7, 2012, the suspect came into the office of the pharmaceutical company he works for and fired numerous shots from Saiga and Benelli shotguns that he owns,” the statement said.
