Story highlights The young man consumed three caffeine-laced drinks in a two-hour period

Father: "It wasn't a car crash that took his life. Instead, it was an energy drink"

(CNN) Too much caffeine caused the death of a 22-year-old internet sensation from Los Angeles who collapsed during class last month, according to the county coroner.

Paul Denino died from a caffeine-induced cardiac event causing a probable arrhythmia, Vegas County Coroner Gary Watts announced in a news conference Monday. During an arrhythmia, or abnormal heart rhythm, the heart may not be able to pump enough blood to the body, and lack of blood flow affects the brain, heart and other organs.

The young man consumed three caffeine-laced drinks -- a cafe latte, large Diet Mountain Dew and an energy drink -- in a two-hour period before collapsing in his classroom at Spring Hill High School on April 26, Watts said.

Among those at the news conference Monday was the young man's father, Michael Denino.

"Like all parents, we worry about our kids as they grow up. We worry about their safety, their health, especially once they start driving. But it wasn't a car crash that took his life. Instead, it was an energy drink," Michael Denino said of his son's death.
