The same day, Russia declared Andrew Hill had confessed and broadcast a video of him dressed in military garb.
It comes after Shaun Pinner and Aiden Aslin, two further British males, were given death sentences last month.
They were charged with the same offenses as Mr. Healy and Mr. Hill at the hearing in an unrecognized Russian proxy court in eastern Ukraine.
Since then, the European Court of Human Rights has stepped in to urge that the sentence be commuted.
An unidentified representative from the so-called Donetsk People’s Republic allegedly stated in a report by Russia’s Tass news agency that Mr. Healy and Mr. Hill would face trial for their “mercenary actions.”
According to the report, neither man was willing to help the authorities.
The Presidium Network, a local assistance organization, announced Mr. Healy’s abduction early this year and claimed that he and another Briton, Paul Urey, had been operating separately on humanitarian projects close to Zaporizhzhia.
The Healy family, who were “extremely concerned” and wanted their son home as soon as feasible, were in daily touch with the Presidium Network, according to Dominik Byrne, co-founder of the organization.
According to him, the family had spoken to the British government and the Red Cross, which was attempting to gain access to Mr. Healy in order to inquire about his welfare.
Mr. Byrne said it was a terrible scenario for the two individuals, who were probably subjected to continuous interrogation and kept in appalling circumstances.
