(CBS) EVANSTON, Ill. - Harsha Maddula, the Northwestern University student whose body was found in a harbor near the school's suburban Chicago campus, died as a result of an accidental drowning, the Cook County medical examiner's office said on Friday afternoon.
According to the Chicago Sun-Times, the medical examiner's office had no additional information about the circumstances surrounding Maddula's death.
Maddula's family made a statement on Friday morning that they do not believe their son killed himself or that his disappearance was related to a rare form of diabetes that he had.
"There is no reason to believe that Harsha was suicidal or that this had anything to do with his diabetic condition," family spokeswoman and friend Padma Sonti said in a statement to reporters.
Maddula, a biomedical student from New York, was discovered floating in the harbor between two boats by a man fishing off a pier near Sheridan Road bridge. His cellphone was in his pocket along with his wallet and a college ID that confirmed the 18-year-old sophomore's identity.
Northwestern University President Morton Schapiro also issued a statement, extending the school's "deepest sympathies" to Maddula's family.
"The loss of one member of the Northwestern community deeply affects us all," Schapiro said.
