Detention: On February 5, 2025, following a search, officers of the Russian FSB detained Oksana Sotsenko along with her mother, Anna Sotsenko, and took them to an unknown location. For nearly nine months, their whereabouts were concealed. It was only in November 2025 that it became known they were held in Pre-trial Detention Centre No. 1 in Simferopol.

Sentence: As of 22.07.2026, there is no information on a sentence. The Russian Federation accuses Oksana Sotsenko under Article 275 of the Russian Criminal Code (“state treason”). Human rights organizations consider the criminal prosecution politically motivated and emphasize gross human rights violations, including enforced disappearance and prolonged detention without contact with the outside world.

Oksana Sotsenko was born on May 21, 1975, and is a resident of the town of Pervomaiske (Kurman) in temporarily occupied Crimea. There is no reliable information in open sources about her education and professional activities. It is known that she is raising a ten-year-old son with a disability who requires constant care and special treatment.

In the months following the search, the family had no official information about their whereabouts. Human rights advocates classified the situation as enforced disappearance, as Russian security forces did not confirm the women's detention or disclose their procedural status.

Particular concern was raised about the fate of Oksana's young son. After her detention, the child, who has a disability, was left without his mother. Human rights advocates emphasized that such actions by the occupying authorities grossly violate children's rights and contradict international family protection standards.

It was only at the beginning of November 2025 that it was revealed Oksana and Anna Sotsenko were held in Pre-trial Detention Centre No. 1 in Simferopol. Simultaneously, it became known that criminal cases for “state treason” had been initiated against them. Until this point, they had been in complete isolation for nearly nine months without access to relatives or independent legal defense.

According to human rights organizations, Oksana Sotsenko's case is part of a broader campaign of persecution against Ukrainian civilians in occupied Crimea. Following the start of the full-scale invasion, Russia significantly increased the use of the “state treason” article against peninsula residents, and these criminal cases are often accompanied by enforced disappearances, closed trials, and restrictions on the right to defense.

Human rights advocates also note that the case of the Sotsenko mother and daughter demonstrates the practice of collective persecution of family members. Such cases are increasingly recorded in occupied Crimea and are seen as a method of psychological pressure on the civilian population.

As of July 22, 2026, Oksana Sotsenko remains in custody. There is no information in open sources about the case being transferred to court, a sentence being issued, or her release. Human rights organizations continue to demand an investigation into her enforced disappearance and the release of all illegally detained Ukrainian civilians.
