Moscow ? The second Moscow suicide bomber may have been a 28-year-old school teacher from the southern province of Dagestan, a Russian newspaper reported Sunday, quoting the woman’s father as saying he recognized her in a photograph.

Rasul Magomedov told Novaya Gazeta that an acquaintance sent him a photograph of the subway suicide bomber that has been widely circulated on the Internet.

Magomedov said his daughter, Maryam Sharilova, disappeared the day before the March 29 bombings that killed 40 rush-hour commuters and wounded at least 121 in Moscow.
