I NEED 2 KNOW THE NAME OF THIS MOVIE WATCHED 17YRS AGO!! PLS HELP!!!!?

2 beauty pageant sisters living with their parents. The younger one gets abducted. She was pulling into her house and she got out and collected the mail and was abducted from there. She was i think diabetic or asthmatic. Mive search begins, they dont find her for quite a while. When they eventually do, she is dead and they believe shes been dead the day she was abducted. A loner who lived down the road was charged with her murder ( i think, based on my memory). I think it was a true story. Any ideas??? I watched it about 17yrs ago.
