It is being reported that Dearon was found unresponsive at this home in Los Angeles on Thursday morning. His family believes that he may have suffered a heart attack — he underwent major heart surgery in 2009 to replace an aorta and fix a leaky valve — although the exact cause of death has yet to be revealed.
