Mr Popovs interrogation does not fit within a frame of investigation..
Popov's document belongs to the case and for Ivanov it represented one of many conclusive pieces of evidence, therefore it is included in the case file.
Sorry Suri, I meant in the context of this statement.
"They also had no idea which direction the hikers might depart. The search team returned to the base and informed their commanders about the tent. The commanders in turn informed Moscow, special Prosecutor's office investigation team was set up, and interrogations started to understand what had happened. Mr. Popov was one of the first to be interrogated."
If a rocket part fell on 1079 on the 1st , it leaves little time, first to find the missing rocket part , then get a reaction force together , then lift it if possible, then inform Moscow, then set up an investigation team , then contact a local police officer to ask a Mr Popov what he saw mid January. It makes no sense.
I see that interview as a routine questionnaire that happens perhaps quarterly or monthly. A standard procedure.
