Cripe’s dad, Sean, urged other parents during the press conference to speak with their kids about the dangers of energy drinks.
"It wasn't a car crash that took his life. Instead, it was an energy drink," he said. "Parents, please talk to your kids about these energy drinks. And teenagers and students, please stop buying them."
