Other senior linked to killing also disciplined Brittany Smith, an aspiring lawyer from Harlem and one of two Harvard seniors linked to last month's killing in a Harvard dormitory, will not receive her diploma tomorrow, according to three officials familiar with her status. Smith is the second Harvard woman barred from graduation following the homicide, which authorities described as a botched drug robbery. A suspected drug dealer from Cambridge was shot inside Kirkland House and later died. Smith's longtime boyfriend, Jabrai Jordan Copney, was arrested and charged in the crime. Her friend, Chanequa Campbell, has publicly criticized Harvard for barring her from graduation. But Smith has been quiet, and neither she nor her lawyer could be reached yesterday. Harvard University spokesman Kevin Galvin declined to comment about the status of Smith or Campbell yesterday. "The university has taken appropriate steps based on information we have learned about two female students identified by the Middlesex County district attorney's office after the fatal shooting at Kirkland House," Galvin said in a statement. "But federal law and Harvard policy prevent us from commenting on the identities of those students or the steps that have been taken." Neither Smith nor Campbell has been charged. District Attorney Gerard T. Leone Jr. has said that drugs were the common denominator that linked the two Harvard women with the suspect and victim, 21-year-old Justin Cosby. Copney and two other New York men had allegedly come to Harvard to rob Cosby of a pound of marijuana and $1,000 in cash, which were found by Cosby's side after he collapsed outside the dorm. The other two men have not been caught. Copney has pleaded not guilty and is being held without bail. Leone said the men were able to enter the locked dorm because one of the women provided her electronic-access card. Campbell, who lived in Kirkland House, has repeatedly denied doing so, telling the Globe in a previous interview that she was taking a final and working the day of the shooting and had her key card with her at all times. Copney and the two men hid the gun in Smith's dorm, Lowell House, police have said. The weapon was found in a friend's room that Smith frequently used to store her belongings, said a law enforcement official familiar with the investigation. Copney had visited frequently from New York and stayed with Smith for weeks at a time, friends have said. Following the shooting, Smith spent several nights at the university health clinic, where Campbell visited her, Campbell told the Globe. But the two have not spoken "in any substantive way" in the days following the shooting, she said. Smith graduated from Frederick Douglass Academy, a public school in Harlem, in 2005. During her years at Harvard, she was active in multiple community service organizations, mentoring, and afterschool programs, said a friend and classmate who did not want to be named because of the ongoing investigation into the killing. Harvard honored Smith with a university public service award last year. She had spent much of her free time in Harlem and had planned to return there after graduation to be a community organizer, the friend said. Smith had also expressed interest in attending law school.
