More than 20 families of Jehovah's Witnesses have become victims of criminal prosecution, including Alam Aliyev,Valeriy Kriger, Sergey Shulyarenko, and Dmitriy Zagulin. The believers were charged with holding meetings for worship, which the investigation deemed to be the organizing the activity of an extremist organization and financing it. They spent more than 5 months in pretrial detention. In November 2020, the case went to court. The hearings lasted more than 2 years, and in December 2022, the court sentenced Zagulin to 3.5 years, Aliyev to 6.5 years, and Shulyarenko and Kriger to 7 years in a penal colony. The court of appeal upheld the terms of Zagulin and Aliyev and reduced those of Shulyarenko and Kriger by 3 months. The court of cassation upheld the verdict in March 2024. The wives of three of the convicts were also prosecuted:
Svetlana Monis, Tatyana Zagulina and
Natalya Kriger. In September 2023, Sergey Shulyarenko's wedding took place in the penal colony.
