In 2015, Irina Danilovich was actively involved in the operations of the library branch of the Ukrainian Cultural Centre. In this role, Danilovich frequently gave interviews to the publication "Krym.Realii" and expressed her love for Ukraine. She collaborated with the independent publication "INzhir Media" and the human rights project "Crimean Process." In 2020, Danilovich assumed the position of the head of the Crimean branch of the trade union Alliance of Doctors. Even before facing criminal prosecution, law enforcement authorities subjected the nurse to pressure. In 2016, she was detained at the entrance to Crimea from mainland Ukraine, along with two other activists of the Ukrainian Cultural Centre. During this incident, the Russian Federal Security Service (FSB) interrogated them, inquiring about her travel to the mainland and her contacts. In 2017, Danilovich recounted to "Crimea.Realia" that FSB officers attempted to compel her to act as an informant. She mentioned that she was summoned without formal summons, subjected to pressure, and threatened regarding the validity of her Ukrainian passport. Irina Danilovich went missing on April 29, 2022. She later informed the court that she had been abducted by Crimean FSB officers on that day. According to her account, she was forced into an unmarked car at a bus stop, where she was threatened, subjected to physical violence, and had her phone and tablet confiscated. After arriving at the FSB office in Simferopol, she was blindfolded with a black bag and taken inside the building. She recalled, "Despite the black bag, I could see my feet as I entered the building. I was led through the metal detector frame, which did not react in any way." While searching Danilovich and her belongings, a security service employee checked a case containing glasses, which later law enforcement officers would allegedly claim contained explosives. She remembered this moment clearly, as the employee took out the case, opened it, identified it as containing glasses, and checked it with a metal detector. However, according to her, there were no explosives or prohibited items in the case. Subsequently, law enforcement officers searched her residence. Following the search, Danilovich was taken to the basement of the FSB building. She described it as cold, with constant bright lighting. She was provided with minimal food and had no access to restroom facilities. She endured these conditions for about eight days. During this time, law enforcement officers regularly visited her in the basement, threatening her life, attempting to obtain information about the "Alliance of Doctors," participants in "Crimean Solidarity," and independent journalists in the region. Danilovich also claimed to have been subjected to polygraph testing. One day, a bag containing a glasses case was taken from her, raising suspicions that prohibited items could have been planted. Danilovich also mentioned that she was coerced into providing her consent for "operational-search measures." Authorities forcibly obtained her fingernail clippings, hand wash samples, and buccal epithelium. She was also forced to record a video statement asserting that she had not experienced mental or physical abuse. Under duress, she signed protocols and two blank sheets of paper without reviewing their content. Following these events, Danilovich asserted that she faced physical abuse by law enforcement officers. This allegedly occurred after she was informed that explosives had been found in the glasses case. Subsequently, she was taken to an investigator, placed in temporary detention, and then transferred to pre-trial detention. From the moment of her disappearance, Danilovich's family, friends, and a lawyer, according to their agreement, began searching for her. Her father managed to obtain surveillance footage near a petrol station, which depicted the abduction of his daughter. In June 2022, the Department of Justice (DOJ) designated Danilovich as a "foreign agent" in the media registry. Danilovich faced repeated extensions of her pre-trial detention, despite unsuccessful defense appeals. In August 2022, she was formally charged, and her case was transferred to Feodosia City Court. It was later revealed that Danilovich had initially been detained on suspicion of state treason (Art. 275 of the Criminal Code) due to her alleged ties to Ukrainian intelligence. The investigation claimed that since 2018, Danilovich had been collecting data on the movement of Russian military equipment in Crimea. During her week in the FSB basement, she was persistently questioned about this, including through the use of polygraph testing. Ultimately, the charges against her did not include Art. 275 and any association with foreign intelligence services. While in pre-trial detention, Danilovich's health deteriorated significantly. She developed otitis media but was not provided with medical treatment. As a result, she nearly lost her hearing and experienced severe headaches due to ear inflammation, according to human rights activists. In November 2022, Danilovich reported instances of pressure from law enforcement officers who conducted an unscheduled search of her cell and confiscated her records. During the trial, the defense repeatedly raised concerns about the judge's bias, especially when questioning witnesses, particularly the comprehensive ones. Danilovich claimed she had never seen them before, including during the search when explosives were allegedly discovered in the glasses case. The defense also highlighted numerous inconsistencies in witness testimonies, inadmissible evidence, lack of substantial proof, and perjury by one of the "witnesses," who was revealed to be a Crimean police officer. The investigation failed to clarify why the activist was carrying explosives and the source of these alleged items. In December, during the trial's closing arguments, the prosecutor requested a seven-year prison sentence and a fine of 60,000 rubles for Danilovich. The Feodosia City Court nearly accepted this request and sentenced the activist to seven years of imprisonment and a fine of 50,000 rubles. Danilovich's health continued to deteriorate, leading her to initiate a hunger strike in March 2023 due to the absence of medical care. In April, she was deceived into ending her hunger strike with promises of hospitalization, but she only received medical attention once thereafter. Activists reported that there were plans to transfer Danilovich from pre-trial detention to a hospital; however, the judge scheduled a date for her to review the case materials on the same day, deliberately obstructing her access to medical care and preparations for appealing her sentence. Danilovich's father later revealed that she had almost completely lost her hearing while in pre-trial detention. By the end of June 2023, the Supreme Court of Crimea reduced Danilovich's original sentence by one month. In July, it was announced that she would be transferred from Crimea to a correctional colony in Krasnodar to serve her sentence. In October, reports were indicating that Danilovich may have experienced a stroke while in pre-trial detention.
