The cause of death of a 19-year-old sophomore at Yale University who was found dead Sunday remains undetermined.

A spokeswoman for the Chief Medical Examiner says an autopsy was done Monday and the results are pending further studies.

Yale spokesman Tom Conroy says that Andre Narcisse of Roosevelt, N.Y., was discovered unresponsive at about 11 a.m. Sunday morning in his suite at Branford College, one of the school's residential colleges.

Emergency personnel were not able to resuscitate him, and he was pronounced dead at the scene.

Conroy said police have not found any evidence of foul play.
