The bodies of two teenagers were discovered Friday morning in an empty Huntington Beach apartment, and today local authorities say their deaths were drug- or alcohol-related, reports the Daily Breeze. Found on the scene: An empty bottle of Four Loko, the booze-infused sugary energy drink that has been banned in some states. The deceased are a 15-year-old boy from Westminster and a 16-year-old girl from Huntington Beach. Authorities say they found "other evidence of drug and alcohol use in the apartment," and the investigation is ongoing.
