In the early hours of an incident like this, a lot of inaccurate and misleading information can be broadcast--with claims that it comes from a reliable source! The JFK assassination, the Reagan Assassination attempt, and 9/11 are prime examples of such information glitches. There WERE reports that cell service had been suspended downtown in early newscasts, so don't "blame the messenger." Musiconradio.com was going on information he or she had at the time. In the morning, we will hear even more changed information. That's just how it goes.
It's really a time of chaos for the media, and everyone else. It's not a time of one-upsmanship.
