Five people may have died over the past three years after drinking Monster Energy, a popular energy drink that is high in caffeine, according to incident reports recently released by the Food and Drug Administration.

The reports, like similar filings made with the FDA in cases connected with drugs or medical devices, do not prove a link between Monster Energy and the deaths or health problems. The records were recently obtained under the Freedom of Information Act by the mother of a 14-year-old Maryland girl who died in December from a heart arrhythmia after drinking large cans of Monster Energy on two consecutive days.
