(WIS) A South Carolina teenager's death is being blamed on a caffeine overdose.

Richland County Coroner Gary Watts held a news conference Monday to discuss the results of the investigation into the death of Davis Allen Cripe, who died on April 26 at Palmetto Health Parkridge Hospital after collapsing in a classroom.

"We lost Davis from a totally legal substance," Watts says. He determined Cripe died from a caffeine-induced cardiac event after drinking an energy beverage along with other caffeinated drinks.
