The Los Angeles Coroners office announced that Heavy D passed away from a blood clot found in his lungs among other issues. The terminology is a pulmonary embolism which if untreated immediately, can prove to be fatal. D had just come back from London after performing at the Michael Jackson tribute show. It’s being said due to the long flight and inactivity, this is the main reason behind the clot being formed in his leg, or as the medical field calls it, deep leg thrombosis.  This is a tragic loss for the entire music industry. Dwight died November 8th, 2011.
