How the hunt for evidence of Russia's war crimes forced a family in Ukraine to bury a beloved son...

The first Russian soldier convicted of war crimes in Ukraine asked his victim's family to forgive him in a Kyiv courtroom on Thursday.

"I know that you will not be able to forgive me, but nevertheless I ask you for forgiveness," Sergeant Vadim Shishimarin, 21, told the wife of the 62-year-old whom he admitted on Wednesday to killing in the early days of the war. Shishimarin faces up to life in prison.
