The Los Angeles Coroner has ruled conservative website publisher and author Andrew Breitbart died of heart failure stemming from coronary disease.
Coroner spokesman Craig Harvey told the Associated Press Friday that a negligible amount of alcohol was found in Breitbart's system but that no prescription or illicit drugs were present.
No significant trauma was present and foul play is not suspected, a release from the Department of the Coroner stated.
Harvey told the AP the case has been closed.
Breitbart died March 1 at the age of 43.
