Investigators in Toronto have turned to a popular American crime show for help with the case of missing teen Mariam Makhniashvili.

America's Most Wanted is now featuring the girl's disappearance on its website.

The site reveals a few new details about the case.

Toronto police have said that Mariam walked to Forest Hill Collegiate on Sept. 14 with her brother George but opted to go into the high school from the front entrance rather than the side door.

The website says Mariam and her brother -- who were both new at the school this year -- took the same route to school everyday and always went in through the side entrance. On the day Mariam disappeared, she broke the routine by going in through the front entrance.

Mariam never made it to class and hasn't been seen since.

The website also says that George first noticed Mariam was missing at noon when the girl failed to meet him for their lunch date.

As both students were new to the country and had limited knowledge of English, neither had made any close friends at the school. George figured she had gone home sick and walked home from school alone that day.

When he arrived home, Mariam wasn't there. Her concerned parents called police.

Toronto police have interviewed the girl's classmates and her friends back home in the Republic of Georgia, but each time, were told that the girl was a very introverted teen whom many did not know very well at all.

The only strong clue to Mariam's disappearance came on October 8 when someone discovered the girl's missing backpack at the back of a building on Eglinton Avenue, a few blocks east of Forest Hill Collegiate.

The spot is known to be a popular thoroughfare for students walking to nearby high school North Toronto Collegiate.

Police have since seized the family's computer plus 27 computers from local libraries but according to AMW, the search turned up little evidence.

The case has posed a significant challenge to Toronto police who say they have not been able to determine whether to classify the case as a criminal investigation, as there is no evidence of foul play.

Anyone who has seen the teen is being asked to call investigators at 416-808-5300 or Crime Stoppers at 416-222-TIPS.
