Events of Criminal Case
Nina became a suspect after the player and Carmen identified her on a picture of her with the victim. She was saddened at the victim's death, even to the point where she doubted she could answer the police's questions. When asked about the victim and any possible enemies of his, she said he was kindness itself and was so good to her. Carmen decided to wait and talk to her again when she started to calm down.
Nina was interrogated again regarding a pregnancy test found outside the train. After analysis from Lars, he confirmed the urine belonged to her and it turned out positive. When she told the victim, he became furious saying he was not in it for the diapers, which enraged Nina. She packed up her suitcase, prepared to walk back to Moscow so she may never see the victim again, saying all he cared about was that cave and his diamonds. Having investigated that same cave a while ago, Carmen asked what the victim told her about it, but Nina said she did not listen to a word he said.
Nina was revealed to be innocent after the team incarcerated Nikita Rukhin for Ilya's murder.
