A brilliant scholar from Brooklyn is being eyed as the possible link between a slain pot dealer and three men who killed him in her Harvard dorm last week, sources said.
Chanequa Campbell, 21, has been banned from the campus and told she won’t be graduating with her class next month as authorities continue to investigate the murder of Justin Cosby, her lawyer said.
“I’m hurt and I’m confused,” Campbell told The Post last night. “For me not to be graduating is frustrating.
“Harvard is doing this to me because I’m black, I’m poor and I’m from Brooklyn.”
Investigators suspect Campbell used her swipe card to help Cosby — who lived in Cambridge but did not attend the university — gain access to the locked dorm to sell drugs on campus, the sources said.
But Campbell insisted she doesn’t know Cosby.
“I’ve never seen him before,” she said.
A second Harvard senior who has been questioned in the case, Brittany Smith, 22, will be allowed to graduate June 4 as planned.
Smith is the longtime girlfriend of accused killer Jabrai Jordan Copney, 20, a Harlem musician and son of a retired NYPD cop, who turned himself in on Thursday.
“This is incredibly hurtful to know it’s only me that has been kicked off campus,” Campbell said. “I’m feeling I’m being scapegoated and I can’t defend myself.”
She admitted to knowing Copney, but only through Smith.
Campbell, who suffers from the autoimmune disease lupus, is a sociology major and National Merit Scholar. She has won scholarships from Goldman Sachs, Coca-Cola and The New York Times.
She was a star student at Brooklyn’s Packer Collegiate Institute and is a member of the National Honor Society.
“I’ve been practicing law for almost 17 years and have rarely come across someone as highly educated and articulate as Chanequa,” said her lawyer, Jeffrey Karp.
He said his client worked four jobs to pay for her education.
“Harvard is being cold and callous,” the lawyer said. “What they have done to Chanequa is equivalent to having your house foreclosed and losing your job on the same day.”
Karp said the school did not give a reason for barring Campbell from graduating, but he’s still hopeful that something can be worked out to let her participate in the ceremony.
