The man said to have coaxed Ottawa student Nadia Kajouji, 18, into suicide will not face charges, according to media reports.

Nadia's mother, Deborah Chevalier, says she was told this by police and provided a tape of the briefing to the Ottawa Citizen.

Kajouji, who had clinical depression and was being treated by officials at Carleton University, threw herself into the Rideau River in March 2008.

Prior to her death, she befriended a woman in an online chat room who called herself 'cami', who Minnesota police say is William Melchert-Dinkel - a resident of that state.

The woman encouraged Kajouji to hang herself in front of a web camera.

Authorities in Minnesota are considering charges against Melchert-Dinkel, 47, in connection with at least one case involving an assisted suicide.

However, the lead investigator in Kajouji's case - Staff-Sgt. Uday Jaswal - is said to have told Chevalier that he isn't satisfied a criminal offence happened.

Section 241 of Canada's criminal code states: "Every one who counsels a person to commit suicide, or aids or abets a person to commit suicide, whether suicide ensues or not, is guilty of an indictable offence and liable to imprisonment for a term not exceeding fourteen years."
