The woman killed in the subway yesterday has been identified. Rose M. Mankos, 48, was a lawyer who lived in Stuyvesant Town. She was on the 77th Street platform on the 6 line Thursday afternoon when she dropped her bag on the tracks and climbed down to retrieve it. She couldn’t get back up quick enough to evade the train — others in the station reportedly cried for her to lay in the trough between the tracks so that the train might pass over her, but Markos froze, and the train crushed her into the platform, severely injuring her skull. The bag contained her ID, a cellphone, gym clothes, and deodorant.
