Friends and family say that the body of a young woman recovered from the Rideau River behind St. Paul University in Ottawa is that of missing Carleton University student Nadia Kajouji.

The body was discovered by a passing boater just after 11 a.m Sunday morning.

Ottawa police have not yet confirmed that the body is Kajouji, from the greater Toronto area, and say that foul play is not suspected in the case.

"(There are) no visible signs of trauma other than those associated with being underwater for a long period of time," said acting inspector John Maxwell.

An autopsy has been ordered to confirm the remains are those of Kajouji, who went missing six weeks ago.

On Sunday, hundreds of people posted notes of condolences to Kajouji's family on a Facebook group web page.

Carleton University President Dr. Samy Mahmoud issued a statement on Sunday, saying "I am profoundly saddened by the news of the reported discovery of Nadia. After widespread collective efforts to find Nadia safe and sound, this is the saddest possible outcome for her family, friends and classmates. "

The 18-year-old Brampton native's family said she was depressed and not acting like herself in the days leading up to her disappearance. Although her family said they knew something was wrong, her father, Mohamad Kajouji said he had no idea how deeply distressed his daughter was.

He had told CTV News that his daughter had tried to harm herself before and was receiving counselling and taking medication.

Kajouji was last seen leaving her dorm room in Ottawa on March 9 after spending her university reading week with family.
