Who is Lagutin? ProPublica provides few details about him, describing him as a person who held senior positions at a Russian defense company and a state energy company.
- ️The description matches the 54-year-old son of prominent Soviet boxer Boris Lagutin.

When Proekt investigated the company’s activities in 2020, one of its journalists was placed under surveillance in Yaroslavl.
