His mother, Nadezhda, married a section chief of the Chita police, Aleksandr Petrovich Melnikov, in 1919.

At the end of 1933, as a student of the Harbin Teacher's Institute, Okhotin joined the Party and remained a member until 1943.

Defendants in one case were combined as follows: Grigory Semyonov, Konstantin Rodzaevsky, General Lev Vlasyevsky, General Alexey Baksheev, Ivan Adrianovich Mikhailov (Minister of Finance in the Government of Admiral Aleksandr Kolchak), Lev Okhotin, Prince Nikolay Ukhtomsky, and Boris Shepunov.

On 30 August 1946, the Military Collegium found the defendants guilty, and Okhotin, along with Prince Ukhtomsky, "given their relatively smaller role in the anti-Soviet activities", were sentenced to 15 and 20 year terms in a work camp respectively.

According to article 58-10 Part 2 (anti-Soviet agitation and propaganda) of the Criminal Code of the RSFSR, the cases against all defendants were dismissed for lack of evidence.
