Naeem Davis, 30, was taken into custody for questioning Tuesday after security video showed a man fitting the suspect's description working with street vendors near Rockefeller Center. Police said Davis made statements implicating himself in Ki-Suck Han's death.  Witnesses told investigators they saw a man talking to himself Monday afternoon before he approached the 58-year-old Han of Queens at the Times Square station, got into an altercation with him and pushed him into the train's path.(AP Photo/Bebeto Matthews)
