Latrese Curtis died of apparent wounds caused by a sharp object, according to the Wake County Sheriff's Office.
But there are more questions than answers surrounding Curtis' murder.
The 21-year-old's body was found along I-540 during Wednesday morning's rush hour.
The Wake County Sheriff's Office has ruled out an accident. They tell Eyewitness News they have not made any arrests but are conducting interviews. They are not saying who they are interviewing.
Curtis' body was spotted by a passing driver. About an hour later, her husband reported her missing to Durham Police.
The case is being investigated as a homicide.
"I hate that it's happening to an HBCU more than anything, with it being a historically black college," NCCU student Willis Ingram said. "But I think it's a tragic thing to happen."
Wednesday, NCCU's chancellor released a statement saying the university was saddened to hear of Curtis' death.
"The entire university community is saddened by the death of this student and we offer sincere condolences to her family at this difficult time," Chancellor Charlie Nelms said. "The safety and security of our students is of utmost importance and we have a number of strategies in place to ensure the safety of our students on campus."
Three Central students have been murdered in the past year. In addition to Curtis' death, Denita Smith and Ebony Robinson were shot to death last year.
