Eddie Guerrero, a late WWE legend, faced a mysterious death that stirred his fans and supporters' curiosity.

Seventeen years after Guerrero tragically died, "Autopsy: The Last Hours Of..." starts exploring his life as a legendary man from a family of wrestlers.

The latest installment gathers statements from experts, sources, and people who were close to Guerrero to share shocking new details about his death. Those opinions are also expected to help divulge the secrets that are yet to be known.

Dr. Michael Hunter reveals that Eddie Guerrero's cause of death seemingly took his life little by little.

"So far, I've discovered that Eddie Guererro's exposure to an often reckless lifestyle may have contributed to his premature death. A history of steroid abuse contributed to his weakened cardiovascular system," he says, as quoted by OK! Magazine.

The series also discovers the wrestler's drinking habit at a very young age. He reportedly had his first beer when he was 10 years old, and the addiction grew from there until he became an adult.

Head of security for WWE, Jimmy Noonan, says that Guerrero turned himself to the substance to make himself feel better when he was alone on the road.

REELZ will present the full documentary "Autopsy: The Last Hours of... Eddie Guererro" on May 8.

How Did Eddie Guerrero Die?

The WWE superstar left the world in deep shock when he was found unconscious inside his hotel room at the Marriot Hotel City Center. His nephew and fellow WWE superstar Chavo Guerrero was the first one to discover his body.

In an interview with Vice (via Complex), Chavo said that Guerrero did not respond to a hotel security's wake-up call.

When he checked his uncle, the late wrestler was purportedly lying on the bathroom floor while holding a toothbrush. He died in Chavo's arms while waiting for 911 responders.

Bleacher Report announced that the then-38-year-old suffered an acute heart failure due to his underlying atherosclerotic cardiovascular disease.

According to Heart Research Institute, the disease is caused by plaques that are made up of fat, cholesterol, calcium, and other substances. They then cause build-up in the walls of arteries that eventually limit or block the flow of oxygen-rich blood to a person's organs and body parts.

In 2009, Rey Mysterio seemingly disclosed that the late wrestler also went through drug addiction as he announced that he would be entering rehab to fix his pain killer addiction. He started to do so as he did not want to face the same fate as Guerrero.

Guerrero infamously got involved in a 1999 car crash that made him become dependent on pills. Two years later, he admitted himself to a treatment center. Experts also believe that he used performance-enhancing drugs for a long time until they hurt his heart.
