In response to the death of a teenager who died after drinking caffeinated energy drinks over a period of days the Chicago City Council is considering legislation banning high caffeine energy drinks in the city.

Among those testifying in today's hearings is Wendy Crossland whose 14-year old daughter Anais Fournier died in 2011, allegedly after drinking Monster energy drinks in the days leading up to her death.

Although the teen had a cardiac condition known as Ehlers-Danlos Syndrome, the Maryland Medical Examiner ruled that Fournier's death was caused by "caffeine toxicity."  The family sued the manufacturer claiming that it failed to provide warnings about the caffeine content of the product.

The Food and Drug Administration is investigating as well to determine whether at least five other deaths may have been caused by energy drinks.
