A study at UNC Charlotte has students trying to prevent underage alcohol sales. They're testing out local businesses to see if they ID.

Grad student Diana Bailey is older than 21, but you wouldn't know that for sure by looking at her.

She's one of a group of UNC Charlotte students trying to curb underage drinking.

“Really our goal is to reduce the amount of alcohol that is sold to kids that are underage,” Bailey said.

UNCC has paired up with the Charlotte Mecklenburg Drug-Free Coalition since 2007, conducting alcohol purchase studies. Students 21 and older go into stores to see who's asking for IDs.

“These places need to know that they should be carding anybody who looks under 30,” Bailey said.

Eyewitness News rode along with Bailey. Her first stop was at a Harris Teeter on Park Road. Her plan if she were asked for an ID was to say she doesn't have it.

Minutes later, she walked out with no alcohol.

“Yeah, he did ask for the ID,” Bailey said.

The next stop was a Circle K on South Boulevard. Again, Bailey walked out with nothing.

But at a Rite Aid on Park Road she walked out with a bag in hand.

“I went in and got Smirnoff Ice,” she said.

Another store that did not card her was a BP gas station on South Boulevard.

After nine total stops, two stores sold alcohol to Bailey with no ID.

“These findings will be turned over to the Drug-Free Coalition, and they'll send members out to visit these establishments,” Bailey said.

The coalition will then offer free training to the stores on how to properly ID.

While Bailey was happy with her run, she said she would have been happier to leave with nothing.

“Somebody that's desperate and wants alcohol that's underage can get a six-pack and a can of Four Loko,” Bailey said.

UNCC will publish the full study in the next couple weeks. Then it will hand everything over to the alcohol law enforcement agency.

While BP had no comment, Rite Aid said:  "All associates receive training on our procedures and policies regarding the sale of alcohol.... Our local management team is taking this as an opportunity, and will immediately visit with the entire store team.”
