One of the Lugansk militia officers responsible for Savchenko's capture and handing over to Russia has come forward (though only through his callsign and not his real name) that the trial of Savchenko is farcical and that, while he holds her personally responsible for the death of the two journalists, he challenges the assertion that she illegally crossed the Ukrainian-Russian border of her own will. He's also upset that the investigators describe the battlefield so poorly and did not approach him for a statement.
The commander called "Ilim" is believed by "Peacekeeper" to be Andrey Tikhonov, a Ukrainian citizen from Kharkov, and spoke to a reporter from Meduza, which is a Russian-language news site based in Riga, Latvia. This kind of interview would not be published in Russia.
