The Brampton parents of a missing Carleton University student are offering a $50,000 reward for her safe return.

Nadia Kajouji, 18, has not been seen since March 9 when she returned to Ottawa after spending reading week with her family.

Her father, Mohamad Kajouji, and his wife Deborah Chevalier have been desperately searching the streets of Ottawa for the first year public affairs and policy management student. She was last seen near the residence building.

However, after two weeks without any word, Mohamad Kajouji says he is starting to lose hope.

"I expect the worst, to be honest. I really do," he told CTV News on Friday. "I have hope...But my hope is just limited, it can only go for so much. If she does come back it will be a miracle."

Nadia Kajouji sent an email to a friend at about 11:30 p.m. on the night she disappeared saying she was going skating. Her wallet was found in her dorm room and her stereo was left on.

Her brother, Toronto resident Marc Kajouji, is unhappy with the way the police have treated the case. He's frustrated it took detectives more than a week to review outdoor surveillance footage from her residence and two days to interview her friends.

However, Ottawa Police have said they do not suspect foul play and have been restricting their search to wooded areas and waterways in the vicinity of her school.

"The worst of this right now (is) not knowing," Marc Kajouji told CTV Toronto on Friday. "Nobody vanishes... That's the scary part: there's been no activity, no bank cards... Where is she, then? My worst fear is that she was abducted."

According to Chevalier, who spoke with CTV Ottawa last week, Nadia had seemed depressed before her disappearance and had been in an argument with her boyfriend on the day she went missing.

She is described as being of a Mediterranean complexion with dark skin, five-foot-eight-inches tall and 130 pounds. She has hazel eyes, shoulder length brown hair with blonde streaks and has eyebrow and tongue rings.

A Facebook group has been created to help assist with the search.
