from 205 unclaimed bodies in morgues of Kiev region only 23 have gun wounds, many bodies do not have any signs of violent death, most are clearly victims of explosions or dug out from rubbles of buildings
It is claimed that they were detained on 23 of March, but it is not clear if they were detained by Russia or SBU.
Ukrainian officials claimed they were on prisoner exchange list this should be easily verifiable.
Here is a link to the interview of a girlfriend of Alexander Suhenko
She affirms that she was informed that the family was on prisoner exchange list, details unclear, but we know at least one similar case. Mayor of Melitopol was exchanged for 7 Ru POWs.
But we also have very different examples from SBU.
On 24th of March the Mayor of Kupiansk recorded a video plea to Zelensky and SBU to release his kidnapped daughter, after she was taken hostage because of his collaboration with Russia.
