The Los Angeles County Coroner said Tuesday that deep leg vein thrombosis also contributed to Heavy D’s death on November 8. The 350- pound rapper had collapsed outside his Beverly Hills condo after he suffered difficulty breathing, police said at the time. He later died at Los Angeles Cedars-Sinai Medical Center.

The blood clot was "most likely formed during an extended airplane ride," Craig Harvey, chief of the Los Angeles County department of coroner told the Los Angeles Times.

Raised in Mount Vernon, N.Y., Heavy D, 44, rose to stardom in the late 1980s as the leader of Heavy D & the Boys. The group was responsible for a string of hits including “We Got our Own Thang” and “Now that We Found Love” through the late 1990s.

Born Dwight Arrington Myers, Heavy D had just released his ninth album in September and had turned to acting. Just recently he played a security guard in the recently released film "Tower Heist," starring Eddie Murphy and Ben Stiller.

His death prompted an outpouring of sadness from fans, stars and politicians.

“This man changed the world and he did it without getting ugly or violent or degrading," Al Sharpton said at the rapper’s funeral, according to several media reports.
