A woman who’s suing a Chicago-based alcoholic beverage company is sending a warning to others. Karla Rupp’s 15-year-old son became intoxicated after drinking two cans of Four Loko. He then walked out into a road where he was fatally struck by a car. The boy and his friends bought the drinks from a convenience store in Virginia without showing any identification.

Attorney Jeffrey Simon said the beverage company and the store should be held responsible.

“So what you have here is a product that was defectively and unreasonably manufactured and marketed all the way through its distribution chain,” he said.

Simon said Chicago-based Phusion Projects, the maker of Four Loko, aggressively markets the sugary drink toward minors.

A statement from the company says it does not condone under-age drinking, and that those who sell alcohol to minors should be fully prosecuted.

Rupp filed a wrongful death suit in Cook County in March. Phusion Projects said a filed suit doesn’t mean the allegations have merit.
