Elizabeth Pena died from alcohol abuse
The Los Angeles County Coroner cited cirrhosis of the liver due to alcohol, as well as cardiopulmonary arrest, cardiogenic shock and acute gastrointestinal bleeding on the actress's death certificate, reported People magazine.
She died in a Los Angeles hospital on October 14 at the age of 55.
Last week, Pena's manager, Gina Rugolo, said the New Jersey-born actress died of natural causes after a brief illness.
Pena's four-decade-long career included roles in 'La Bamba', 'Lone Star' and 'Rush Hour'. Most recently, she played Sofia Vergara's mother, Pilar, on ABC's 'Modern Family'.
