The coroner says three things contributed: pneumonia, damage to the air sacs in his lungs and hardening of his heart muscle with plaque build up within the blood vessels.

On March 10, the 38-year-old actor collapsed at his mother's L.A. apartment after suffering from flu-like symptoms. A drug overdose was originally believed to be the cause of death, but the coroners have now confirmed that drugs were not involved.

Haim was buried on March 16 in Toronto.
