Molloy died Jan. 7 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.
The driver of the Jeep - 16-year-old Garrett Prince - faces a list of charges including felony death by motor vehicle, DWI, and possession of marijuana in the death of his 17-year-old classmate.
According to a crash report, 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.
On Friday, ALE officials announced they had also charged 21-year-old Anthony Du Juan Geter.
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 Jan. 7. Two of those minors were Prince and Molloy.
Geter was charged with four counts of aid and abet after purchasing spirituous liquor.
Wednesday, 17-year-old Samantha M. McKinney was charged with one count of underage purchase of spirituous liquor for allegedly helping to buy the alcohol.
Hannah R. Smith, 18, of Hawksmoor Drive, Raleigh, was charged with two counts of aid and abet after she allegedly hosted an underage party Prince and Malloy attended. Her parents are not facing any charges.
ALE Agent Bryan House said it's an all too common case.
"This case is consistent with other cases where we see underage people being provided alcoholic beverages, consuming alcoholic beverages, and then making a bad decision," said House.
Lori Brown, with Mothers Against Drunk Driving in Raleigh, said the conviction rate in cases like this one is too low.
"There are consequences to all your actions," said Brown. "If you chose to make a bad decision, we all make mistakes, but sometimes those mistakes and those decisions can end in a fatality."
Police say that a 15-year-old girl also helped buy the alcohol and could face disciplinary action in juvenile court.
