Cue further outrage over caffeinated alcohol. Two teens, ages 15 and 16, have been found dead in Huntington Beach, Calif., with an empty can of Four Loko nearby. The drink’s maker announced in November that it would change its formula for the alco-pop by removing caffeine after federal officials warned the drinks were unsafe. But it’s not clear whether the sugary beverage was to blame: Police said there were also signs of drug and other alcohol use, and toxicology tests have not been completed. It’s also unknown whether the Four Loko found in the apartment with the boys’ bodies contained energy supplements.
