Abc's chief investigative correspondent brian ross tells us why the experts are studying every frame of this tape. Reporter: The attack was seen today by security expert as an ongoing salvo by terrorists against next february's olympics. All caught on tape in the city once known as stalingrad by a motorist with a dashboard camera who happened to be trailing the bus. Six people plus the suicide bomber were killed on the bus, which was en route to moscow from dagestan, a stronghold of chechen rebels. Officials in russia today identified the bomber as the 30-year-old wife of known chechen terror leader. Chechen leaders have already publicly announced their intention to disrupt the 2014 winter olympics. This is russia is on the center stage of the world. This is a moment of pride and also a moments of potential vulnerability. Reporter: The bus attack took place 600 miles from where the olympics will be held in the resort city of sochi which sits at the caucus mountains where the insurgency has been raging. President putin says these will be the safest olympics ever. Security is the highest possible level. Reporter: And there is great concern about u.S. And other internet olympic teams, the chechen rebels after years of battling russia forces could seek maximum impact by going after civilians according to a stutdy by the university of chicago. For them the grater the attention, the best it would be for their cause. Reporter: The track record of the chechen group suggests more female bombers could be involved as they have been in previous brutal attacks against the moscow subways, a theatre 11 years ago tomorrow and two commercial airlines including one on its way to sochi, the olympic city. Female suicide bomber is a kind of signature, brian. Thank you so much.
