A senior weapons designer at a Russian weapons factory south of Moscow has been shot dead.
Russia's Investigative Committee said Vyacheslav Trukhachev, the deputy chief designer at a defense facility in Tula, was found dead with a bullet wound in his head late on November 21.
A senior regional investigator, Tatyana Sergeyeva, said the killing was captured on a surveillance camera that showed that the gunman was wearing no mask and fled the scene immediately.
Russia's defense industry, the world's second-largest arms exporter, has been under increasing scrutiny since a nearly $100 million corruption scandal implicated former Defense Minister Anatoly Serdyukov.
He was dismissed earlier this month.
