A year later, a Yaroslavl hydrologist was cleared of a series of murders he did not commit.

scientist Alexandra Tsvetkova Tsvetkova, from the Yaroslavl village of Borok, was detained in February 2023 when he and his colleagues were returning from a business trip. They were arrested right on the plane. presented charges of murders committed in the Moscow region in August 2002.

Artificial intelligence "identified" the scientist as a killer – a portrait of Tsvetkov 55% matched with a composite sketch based on the description of two “witnesses,” one of whom, Andrey Aleshin, he himself was an accomplice to those crimes.

Investigators didn't believe the documentary evidence, photographs, and testimony from Tsvetkov's colleagues that the hydrologist had actually been on an expedition in August 2002. Tsvetkov's relatives, colleagues, and neighbors in the village wrote petitions, appeals, and letters, but they were ignored for a long time.

Finally, the Prosecutor General's Office conducted an investigation and confirmed that the investigation was stalling, and the alibi had not been properly verified. At the Civil Society Development Council, the human rights activist Eva Mercacheva appealed directly to President Putin, and he ordered an investigation.

Tsvetkov was held in Matrosskaya Tishina until mid-December last year. He was released from the pretrial detention center with his health severely deteriorating. He also spent another two and a half months under investigation, with certain restrictions on his activities (including a ban on mobile phone and internet use). According to the publication, 76.ru, the charges against him were dropped only on February 27.
