Ottawa police say they haven't given up on the investigation into the death of Nadia Kajouji, a Carleton University student who threw herself into the Rideau River in March 2008.

An online video diary Kajouji produced in the months leading up to her suicide suggests the first-year university student was struggling with clinical depression and insomnia.

Police in Minnesota are considering charging the man for encouraging Kajouji to take her own life, but Kajouji’s mother has expressed concern that Ottawa police won't pursue similar charges.

Sgt. Uday Jaswal, the lead investigator on the Kajouji case, said Monday that Ottawa police are still committed to the case.

“Not only myself, but the entire investigative team have really made a personal commitment to this case,” Jaswal said.

Section 241 of the Criminal Code states that it's an indictable offence to counsel or assist someone in committing suicide.

Jaswal said he is hoping police in Minnesota can provide more evidence that Ottawa authorities can take to a Crown attorney. Police want to assess how successful a case against the male nurse could be before they decide to pursue charges, he said.

"This is not a closed case. We are still actively investigating this in terms of looking at the possibility of charges," Jaswal said.
