LOUISVILLE, Ky. (WDRB) -- A coffee, soda and energy drink became a deadly combination for a South Carolina teenager.

Authorities say 16-year-old Davis Cripe died from a caffeine overdose. His classmates say he drank a McDonald's latte, a Diet Mountain Dew and an energy drink, all within two hours.

He later collapsed in a classroom and died. His death is listed as the result of a "caffeine-induced cardiac event."

"But what we want to do today is make people understand that these drinks, and this amount of caffeine, and how it's ingested, can have dire consequences -- and that's what happened in this case," said Richard County Coroner Gary Watts.

Doctors say many energy drinks contain not only caffeine, but significant amounts of other stimulants.
