Moscow ( CNN ) Russia 's president shares `` political responsibility '' for the assassination of opposition leader Boris Nemtsov , the late politician 's daughter said Friday in her first TV interview since his death in central Moscow last week . Zhanna Nemtsova , who said she has no faith in the Russian investigation into the killing , said she believes his death will only deter other opposition voices , rather than embolden them . `` I can not blame him ( Putin ) directly , ( but ) I would say that our authorities , including the president of Russia , have political responsibility as the head of state , '' Nemtsova told CNN 's Matthew Chance . Nemtsova says she has no evidence about who ordered the murder , but that `` it 's evident that it 's politically motivated . '' Nemtsov , 55 , was shot dead last Friday night as he walked near the Kremlin with his girlfriend . A former deputy prime minister , he was one of Putin 's harshest critics and had been arrested several times for speaking against the government . No one has been arrested , though Russia 's Federal Security Service chief has said there are suspects . The Kremlin has suggested Nemtsov may have been killed by enemies of Russia intent on creating political discord , but many Nemtsov supporters suspect Putin 's administration of involvement . How Boris Nemtsov 's murder serves notice to Vladimir Putin 's enemies . Putin this week called the killing a `` disgrace '' and a tragedy , and he promised to bring those responsible to justice . But Nemtsova , 30 , said she does not believe that will happen . She said investigators have not contacted her and she knows nothing of the case except what is in the media . `` I do n't know where his cellphone and his personal belongings are , so I know only those things which are released or published in the press and nothing else , nothing else , '' she told CNN from Germany , where she is staying for a few days . `` As I have already said , I do n't have any faith in this investigation . '' Nemtsova said she loved her father `` more than anyone else in my life '' and that the two were very close . `` I think that he died a hero , '' she said . `` He was a very brave man , and he was clever , he was a great thinker and he was a brilliant physicist , '' having published dozens of articles on the subject , she said . He was also an economist and pacifist , she said , who most recently had been critical of the Kremlin 's handling of the Ukraine crisis . `` I know that some Russian officials kept saying that he was not dangerous , but ... in an authoritarian regime , any person who does not agree with politics -- who criticizes the official standpoint -- is dangerous , '' Nemtsova said . `` That 's why , I think , if you look at other regimes , like in Russia , you will see that all opponents to the official line are in danger , under threat . '' Nemtsov was a top official with the Republican Party of Russia-Party of People 's Freedom , a liberal opposition group . He served as deputy prime minister in the late 1990s under President Boris Yeltsin . Early in his career , he was governor of Nizhniy Novgorod , a major economic hub . `` I think that now , Russia has crossed the line after this murder , and people will be frightened to express their ideas which contradict ... the official standpoint , '' Nemtsova said .
