Police said Natalie Chidlaw and Meghan Clark, both 18, were crossing Hillsborough Street in Raleigh just before 1 a.m. when Adekanmbi hit them.
Chidlaw died. Clark was taken to WakeMed, where she was listed in good condition Saturday night.
Adekanmbi faces two counts of felony hit and run causing bodily injury or death and driving while his license was revoked. He was being held at the Wake County Detention Center.
Police found Adekanmbi's Volkswagen sedan in the 100 block of Chalfont Drive in Cary a little more than 12 hours after the crash.
Witnesses and family members were shaken by Chidlaw's sudden, tragic death.
Will Talbot heard the impact from about a block away and rushed to the scene.
"It sounded like a cannon almost. You knew something heavy had happened," he said. "You only hoped for the best when you got there, but when you got there it was like, no. She was out."
June Adamio, Chidlaw's aunt said her niece had a big heart.
"She loved working with animals, and she loved working with children. She went to the Dominican Republic last summer for a mission trip," Adamio said.
Adamio said the her niece and Clark were high school classmates and good friends.
"She went out of this life how she did everyday. Spending time with friends and family, those she loved the most," Adamio said.
