Moscow , Russia -LRB- CNN -RRB- -- Russian investigators have identified the second suicide bomber in last week 's fatal Moscow subway attacks as Maryam Sharipova , a 28-year-old schoolteacher from Dagestan , authorities said Tuesday . Sharipova was born in the village of Balakhani , in Dagestan , a predominantly Muslim republic that lies beside Chechnya , in southern Russia , the Investigative Committee of the Russian Prosecutor 's Office told CNN . Like Chechnya , Dagestan has been troubled for years by radical Islamic violence . The committee said it identified Sharipova through forensic medical examinations . Sharipova and another female bomber , Dzhennet Abdullayeva , detonated their explosives about 40 minutes apart on the morning of March 29 . The blasts ripped through the Lubyanka and Park Kultury stations in central Moscow , killing 40 people and wounding more than 80 . An estimated 500,000 people were riding trains in the capital at the time of the attacks . Sharipova triggered a homemade explosive device at Lubyanka subway station , the investigative committee said . Russian law enforcement bodies are continuing their `` investigative and operational search actions to determine and arrest the organizers and masterminds behind the terrorist act , '' the committee said . The woman 's father , Rasul Magomedov , was flown to Moscow to identify the remains of what was believed to be his daughter , an investigative committee official told CNN on condition of anonymity . Magomedov 's account and forensic analyses left no doubt that the body was that of Sharipova , the official said . Independent Russian newspaper Novaya Gazeta reported Sunday in an exclusive article that Magomedov had identified his daughter in a photograph that was published on the Internet last week . The photograph was described as that of a dead unidentified suicide bomber of the Lubyanka metro station . Magomedov was sent the photograph on his mobile phone , the newspaper said . `` My wife and I have immediately recognized our daughter , Maryam , '' Magomedov told the newspaper in the article , which was reprinted across Russian media . `` When my wife had seen our daughter last , she had been wearing that same red scarf that is depicted on the photograph , '' he said . `` We did n't know her whereabouts ... '' Magomedov said he 'd seen his daughter for the last time on March 26 , while his wife had seen her in the afternoon of March 28 , which was less than 24 hours before the deadly bombing . Several other people who knew Sharipova also recognized her in the photograph , Novaya Gazeta said . Sharipova -- who , like the other children in her family , was given the last name of her grandfather , Sharipov -- was born into a teachers family . Her father teaches Russian language and literature at a local school in Balakhani . His wife teaches biology there . Sharipova attended the same school her parents work in , the newspaper reported . She later graduated from a university in 2005 with a degree in mathematics and another in psychology , the newspaper reported . Recently , she had been teaching computer science at a local school . `` We still ca n't believe what happened , '' her father said , according to Novaya Gazeta . `` We ca n't even imagine how she appeared in Moscow . '' According to the newspaper , Magomedov described his daughter as `` quite pious , '' but he said she never expressed any radical views . `` I totally rule out that someone might have manipulated her psychologically , '' he said , noting that she was a certified psychologist , the newspaper reported . `` She lived with us , worked as a schoolteacher and led an open life , '' he said . A person who knows the Magomedov family very well told the newspaper that Sharipova was a `` calm and confident person . '' The person , who was not identified , said that no one `` ever heard her expressing any extremist opinions or displaying imbalanced behavior . '' On Tuesday , Russian state television , citing law enforcement sources , said Sharipova had been the wife of 35-year-old Magomedali Vagabov , a local rebel leader who has been fighting government forces since the 1990s , and who reports directly to Dokku Umarov , the top Chechen rebel , who took responsibility for the bombings . The investigative committee would not comment on the report . Russian state television also showed video of Sharipova 's village , and spoke to her father . `` When they -LSB- officials -RSB- called me on the phone to tell that she blew herself up in the Moscow subway , I said it must be complete rubbish , '' he recalled in an interview . Last week , the Russian investigative committee identified the first bomber as Abdullayeva , also from Dagestan . Her precise age was n't revealed , but the committee said she was born in 1992 . Russian newspapers reported Friday that Abdullayeva -- whose last name has also been cited as Abdurakhmanova -- was the widow of a prominent Dagestani rebel militant leader who was killed by federal forces in late December . An apparent photograph of Abdullayeva and her late husband , identified as 30-year-old Umalat Magomedov , was published in Russian media . It shows a bearded man with his arm draped over a young-looking teenage girl dressed in traditional Muslim attire . Both are holding guns and looking unsmilingly into the camera . The circumstances of the photograph , including when it was taken , were not explained . CNN could not confirm the authenticity of the picture . CNN 's Maxim Tkachenko contributed to this report .
