He quoted:"He was a scientist, he loved his country, he was working in his country despite many invitations from leading universities and labs to go work abroad. He wanted to work in Russia, he wanted to teach students. These charges are absolutely ridiculous and extremely cruel and unsual to be levied on such a sick man."Dmitry Kolker's daughter Alina Mironova grieved his imprisonment in a post on her VKontakte profile. She wrote:"Stage four pancreatic cancer is a verdict. But to face such a verdict not at home, within the walls of a detention center without proper medical care is the worst thing that can happen to a person."In recent years, a number of Russian scientists have been detained and charged with treason for allegedly transmitting secret information to foreigners.Authorities also detained Anatoly Maslov, the director of the Novosibirsk-based Institute of Theoretical and Practical Mechanics, a few days after Kolker was taken into custody.Russia detained a second scientist in Novosibirsk on charges of state treason, according to Russian news agency TASS on Saturday. It remains unclear whether the two cases are related.
