Agents say the adults who purchased alcohol for the teens and who sold alcohol to the teens will be held responsible.
Bryanna Hamilton, 17, was driving a SUV that crashed and killed two of her passengers on August 6. Authorities say the teens were at a party and were drinking before they left.
Hamilton is charged with two counts of felony death by motor vehicle and two counts of felony assault by motor vehicle. Denzel Graves, 16, died at the scene, and Cheyenna Cummings, 18, died a day later at the hospital.
On Monday, agents arrested Natasha Clark, 20, for allegedly selling alcohol to the teens. When asked if she sold the teens alcohol, she said, "No one sold anything to kids."
"It's a very bad idea and not only that, it's against the law and a class one misdemeanor,"ALE Agent David Williams said.
The woman who hosted the party, 21-year-old Tierra Washington, says she is not repsonsible for what happened and says she did not give any of the teens alcohol.
Agents say more arrests are pending.
