A candlelight vigil was held on Saturday.
The investigation into the crash that caused the seventeen year old's death continues.
The crash happened just after 2 a.m. Saturday in the 6700 block of Rainwater Road.
Investigators said Garrett Prince, 16, a fellow Millbrook High School student, lost control of his 1999 Jeep SUV and struck a tree.
He was charged with felony death by motor vehicle, careless and reckless driving, having an open container of liquor, speeding, and possession of marijuana.
Prince was treated at WakeMed for non-life-threatening injuries and taken to the Wake County jail.
His bond was set at $26,000.
Also on Sunday, Superintendent Tony Tata released the following statement:
"The Millbrook High community and all of us in the Wake County Public School System were saddened to learn of the death of one of our students, Elizabeth Molloy, and the injury of another in a vehicle crash early Saturday morning. All of our thoughts and prayers go out to their families, friends and loved ones. If Millbrook students want to talk to someone, our school system will have counselors available for them at school Monday. We appreciate your support of our students and of the entire Millbrook High family in this difficult time."
Prince is scheduled to appear in court Monday.
