The NYPD is saying that the man they believed pushed 58-year-old Ki Suk Han onto the subway tracks yesterday afternoon implicated himself during questioning Tuesday. What exactly the suspect said isn't clear. According to investigators, police took the suspect into custody after seeing his image "at various locations and found people who knew him," but will not identify him at this time. Witnesses say they were unable to help Han because they had all gathered on the other end of the platform to avoid the very panhandler suspected of pushing Han. The New York Post photographer who took the controversial photo of the murder tried to explain himself Tuesday by saying, "I wanted to help him, but I couldn't figure out how to help."
