Ibragim Dadaev, who was in a Perm correctional colony, died due to an incorrect diagnosis. Instead of meningitis, which developed against the background of tuberculosis, they tried to treat him for a stroke. Since the beginning of the year, Dadaev’s condition has been deteriorating: according to the Perm Regional Human Rights Center, his blood pressure dropped, he stopped walking, by January 17 he did not recognize his relatives, and since January 24 he was constantly in a coma.
