On the morning of 7 November 2012, Dmitry Vinogradov entered a Rigla pharmaceutical warehouse on Chermanskaya Street in northeast Moscow with two shotguns and opened fire on colleagues. Five people died at the scene, a sixth died later in hospital, and one other person was injured.
A colleague subdued Vinogradov, and security staff detained him until police arrived. Investigators said he had planned the attack for months and had trained at a shooting range. He also posted hostile writing online shortly before the attack; the case record does not treat that material as justification for the killings.
Court-ordered evaluators found Vinogradov legally sane, while also documenting depression and an unstable mental state. On 9 September 2013, a Moscow court sentenced him to life imprisonment, ordered compensation for victims’ families, and required compulsory treatment. He was later transferred to a maximum-security prison.
