A 30-year-old man has shot dead six co-workers in what was reportedly a drunken rampage in Moscow.
The man, identified as Dmitry Vinogradov, was dressed in camouflage clothing and armed with two semiautomatic weapons.
He went to a pharmaceutical chain where he was a lawyer, shot dead four men and two women. One of the men died later in the hospital.
Moscow police apprehended Vinogradov and said "a girl broke up with him [and then] he went drinking."
The girl reportedly worked at the pharmaceutical chain. She was not among the victims.
The suspect posted a message on the Internet shortly before the killing spree.
Part of the message read, "I hate humanity and life itself. I see only one way to justify it: Kill as many pieces of human compost as possible…"
