HARVARD CELL CLUES

Some Harvard students may have more than end-of-year exams to worry about — cops are rifling through the cellphone records of a murdered local drug dealer to uncover customers’ names.

“They are calling students and asking, ‘Have you ever bought drugs from this person?’ ” said Chanequa Campbell, a 21-year-old senior from Brooklyn who has been barred from graduating for her alleged ties to slain pot dealer Justin Cosby.

Campbell has denied that she even knew Cosby, much less gave him access to her dorm for him to peddle his illicit goods, as authorities suspect.

As for those students who may have bought drugs from Cosby, “Nothing is being done to them,” a bitter Campbell said.

Officials with the university and district attorney’s office have refused to answer questions about the case.
