It is unknown what condition Sentsov is currently in as no one was able to reach him out. Sentsov informed his sister on his health problems in a letter in early March.
"For this entire period, for almost 4 years [that Sentsov spent] in prison [being] unlawfully convicted, our consul has been granted no access to the political prisoners. Therefore we get all the information through human rights defenders or his lawyer," Betsa explained.
"We know now that his health has deteriorated. And we urgently sent a note to the Russian Federation to gain access, and if necessary, for the Ukrainian doctors to gain access [to Sentsov]," she said.
As reported, Sentsov’s sister Natalia Kaplan said March 16 that her brother reported on his failing health in a letter. He in particular said that he is losing his hair and has his teeth crumbling into small pieces.
Sentsov is serving a sentence in the maximum security labor camp in the Yamalo-Nenets Autonomous District. This prison's inmates are serving sentences for commission of grave and especially grave crimes.
Earlier, Sentsov was detained by the Russian FSB Security Service in Russian-occupied Crimea in 2014 together with activist Oleksandr Kolchenko. They were brought to Russia and tried in a trumped-up case on charges of organizing acts of terror and arson on the peninsula. On Aug. 25, 2015, Sentsov and Kolchenko were sentenced to 20 years' and 10 years' in prison, respectively. On Oct. 21, 2016, Russia refused to extradite the two Ukrainians to Ukraine, claiming they had automatically acquired Russian citizenship after the annexation of Crimea.
