The minute the father of a missing Carleton University girl saw her dorm room in Ottawa, he knew something was wrong.

Mohamad Kajouji told CTV's Canada AM on Thursday that he got in the car and drove from his home near Toronto to Ottawa on March 9 as soon as he learned his daughter Nadia hadn't been seen in two days.

When he arrived, he found that her identification, money and computer were all still in her room.

"It was all there in the room, just like someone called her and said 'Nadia, meet me downstairs I have something to tell you or I have to drive you somewhere, if you're feeling bad I'll bring you right back.' That's how it looked to me."

Ottawa police had called Kajouji to tell him Nadia was missing. The distraught father said he was shocked to also learn that his daughter -- whom he described as a very competitive girl -- had been upset about her falling grades and had been seeing a counsellor.

He said he learned Nadia had been prescribed medication for depression that needed to be taken under supervision. That was a shock, he said, since the girl had no history of depression and avoided taking medication.

"This was so upsetting to me because my daughter hated taking Aspirin let alone medication like that," Kajouji said, appearing on Canada AM with a stack of the girl's academic accomplishments and awards.

He issued an emotional plea to anyone who might have information about Nadia's whereabouts.

"I would just tell them please, please help me bring my daughter home," he said. "I'm begging you. And if she needs any help I'll do anything in my power to help her."

He told CTV News on Wednesday that he's open to the possibility his daughter might have harmed herself or run away. And investigators have told him Nadia was likely in distress at the time of her disappearance.

"I honestly believe either she run away somewhere to the other side of Ottawa or she's buried here somewhere under the snow and until this snow melts that's the only way we can find answer," Kajouji told CTV News.

Kajouji says he has faith in police and continues to hold onto a fading hope his daughter is still alive.

Nadia went missing from her dorm room in Ottawa after spending her university reading week with family in Brampton, Ont.

Police have searched the water and brush surrounding Carleton University in the weeks following her disappearance and a group of about 100 students is planning a search for Kajouji along the city's O-train tracks between Carleton University and Dow's Lake at midnight Thursday.

Kajouji is described as having dark skin and shoulder-length brown hair with blonde streaks. She is 5'8 and 130 pounds.

Her eyebrow and tongue are pierced.

Anyone who has any information on Kajouji's whereabouts is asked to contact Ottawa police at 613-236-1222, ext. 3726.
