Vadim Zimin was a former colonel in the Russian Federal Security Service (FSS). During his tenure, he was in charge of the presidential nuclear briefcase. He served in this position during the reign of former Russian President Boris Yeltsin.
He was shot in the kitchen of an apartment in Krasnogorsk by his brother, who according to some reports was already in the apartment during the incident, states British Mirror. Zimin, with a head injury, was lying in a pool of blood, and there was a pistol nearby, according to the server.
The shooting took place at a time when Zimin was facing criminal prosecution for allegedly accepting a bribe when he joined the customs service. He was therefore under house arrest for criminal prosecution. He rejected the mistake.
According to the Russian portal mk.ru, Zimin tried to commit suicide due to a bad social situation caused by losing his job. His wife, who works as a nurse, was reportedly not at home at the time of the incident. She treated wounded Russian soldiers at the hospital.
