Anthony Du Juan Geter, 21, was arrested late Friday night by state Alcohol Law Enforcement agents.
According to arrest warrants obtained by ABC11, Geter helped four minors buy two 1.75-liter containers of Bacardi Dragon Berry from the Sandy Forks ABC store January 7. Two of those minors were 16-year-old Garrett Prince and 17-year-old Elizabeth Molloy.
Later that evening, Molloy was killed when the Jeep Grand Cherokee she was riding in smashed into a tree. It happened around 2 a.m. in the 6700 block of Rainwater Road.
According to a crash report, Prince - a classmate of Molloy's at Millbrook - was behind the wheel. Officers said Prince was going at least 75 miles per hour in a 30 mph residential zone when the accident happened. Prince was hurt, but survived the wreck.
Prince remains in the Wake County jail. He faces a list of charges including felony death by motor vehicle, DWI, and possession of marijuana.
Geter was released on $4,000 bond. He faces a possible fine and community service if convicted.
The ALE said it is continuing its investigation and expects to file more charges.
