of a heart attack, according to TMZ.com:
Michael suffered a cardiac arrest earlier this afternoon at his Holmby Hills home and paramedics were unable to revive him. We’re told when paramedics arrived Jackson had no pulse and they never got a pulse back.
A source tells us Jackson was dead when paramedics arrived.
Fox News is waiting for confirmation.
The BBC and others report that the LA Times has confirmed it. The LA Times website
is probably overwhelmed with traffic and shows a blank page link here.
