The 66-year-old singer died on 28 August (16) after suffering a heart attack at his home in Santa Monica, California, sparking an outpouring of tributes from Latin stars including Ricky Martin, Marc Anthony, Jennifer Lopez, and Carlos Vives.

His death certificate, which has been obtained by TMZ.com, ruled his death was caused by arteriosclerotic cardiovascular disease, where arteries slowly become blocked, stopping blood flow reaching the heart.

The document also states a history of pneumonia and diabetes as the other health conditions which reportedly contributed to his death. Hypertension, or high blood pressure, is also listed.

Gabriel had to cancel a series of concerts in 2014 after he was hospitalised with pneumonia. He spent several days in an intensive care unit in Las Vegas.

The singer was cremated shortly after his death, and the urn containing his remains reportedly took centre stage at two memorial concerts, which took place earlier this month (Sep16) in Mexico City.
