Complications relating to alcohol abuse were listed as the causes of death for actress Elizabeth Peña, who died Oct. 14 at the age of 55.

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. She died in a Los Angeles hospital.

Last week, Peña's manager, Gina Rugolo, said the New Jersey-born actress died of natural causes after a brief illness.

"She was our star. She was my star. We celebrated her triumphs. We sweated through her struggles," her nephew Mario-Francisco Robles wrote in an Oct. 15 tribute to his aunt on Latino Review .

"Tonight, my family is heartbroken," he continued. "There's now a void that will never be filled. All we can do now is remember your sharp sense of humor, your endless hunger for life, and your never ending pursuit of happiness."

Peña'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 .

Peña is survived by her husband, Hans Rolla, and two children.
