BUCKHEAD, Ga. -- "They're pretty good for the most part. I've had pretty much all of them."
Dave Dulock is buying three energy drinks. He doesn't choose Monster brand today. Dulock is in one of the most popular corners of the Quick Trip on Sidney Marcus Boulevard -- the energy drink cooler.
Evangelist Cherry likes one called The Rooster Booster.
"I don't know. I guess they make me feel better during the day, just a pick up," she says.
Monster Energy drinks are prominently displayed in the case at the store, but now the FDA is investigating whether this popular brand could be linked to five deaths.
The news of the investigation comes after the family of a 14 year old California girl filed a wrongful death lawsuit against the company. The girl drank two 24 ounce cans in 24 hours.
The teen's cause of death was cardiac arrythmia from caffeine toxicity. The FDA is now investigating four other deaths linked to people who had the drink.
A 16 ounce can of Monster Energy drink has 160 miligrams of caffeine. That's like drinking five regular or diet Cokes, or one full cup of cofee.
Monster has a warning on the label that people should not consume more than three cans in a day and children should not drink them at all.
A spokesperson for Monster says they are "unaware of any fatality anywhere that has been caused by its drinks."
Dulock says, "Oh I know they're not healthy. It's like when people smoke, right? I know it's not healthy so I try to keep it to a couple a week."
