NEW YORK -- There are still missing pieces to the Times Square car bombing puzzle.
The Pakistani-American who police say admitted to the act has made no court appearance since his arrest early this week and authorities remain unsure he was acting alone.
New York City Police Commissioner Raymond Kelly says Faisal Shahzad is cooperating but declined yesterday to reveal what Shahzad is telling investigators, including what his motives were.
Law enforcement officials say they are trying to find links between the Bridgeport, Conn., man and possible financing sources who may have funneled cash to him.
Gen. David Petraeus, head of U.S. Central Command, says the suspect was apparently a "lone wolf" who was inspired by militants in Pakistan but didn't necessarily have direct contact with them.
