Two people allegedly approached the group, produced guns, and opened fire.
Roman was struck in the face by a bullet. She was rushed to Brookdale Hospital, where she was pronounced dead.
Roman's father said he was inside when bullets began to fly, and shortly afterward, picked up his daughter's body.
"I heard chaos, I came out, and I came and grabbed my daughter," said Mario Roman.
Police say they believe Roman was not the intended target of the shooting. She was weeks from her 18th birthday. She leaves behind her parents and two siblings.
