OTTAWA — A missing Carleton University student had the nation’s attention for six weeks in the spring of 2008, and a year later, questions remain about whether someone should be held criminally responsible for Nadia Kajouji’s suicide.


Kajouji, an 18-year-old first-year public affairs major from Brampton, Ont., disappeared from her dorm, leaving her identification behind.


After breaking up with her boyfriend and seeing her grades slip, she became depressed in the weeks leading up to her disappearance.


The weekend of March 15, 2008, nearly a week after the young woman was last seen, Mohamed Kajouji scoured the city looking for his daughter.


He made tearful phone calls to local contacts.

For the next month, he would become a familiar face in newspapers and television reports as he roamed Ottawa.

Ottawa police dedicated numerous resources to the search, including a qualified master searcher.

A police airplane searched from above as officers fanned out around the campus.

Kajouji’s body was found April 20, 2008, on the river’s edge behind St. Paul University.

On Sunday, Deborah Chevalier will walk a path along the Rideau River, retracing the steps her daughter took before disappearing in the river.

It will be the day before the one-year anniversary of the teen’s discovery.

The vigil begins at 2 p.m. at the university.

Several people on an Internet message board have indicated they will be there to support Chevalier and her family.

For Chevalier, it will be the first time she has visited Ottawa since her daughter died.

It’s rare that a suicide gets so much public attention, but Kajouji’s death may have a criminal element.

Police in St. Paul, Minn., aren’t finished their investigation into whether a middle-aged male nurse encouraged Kajouji to take her own life in an online chat.

Investigators have told Kajouji’s mother that the probe is ongoing and they continue to analyze computer data connected to the chats.

No charges have been laid.
