Early one Houston morning on her way to a school for troubled youngsters fate introduced teenager Laurie Lee Tremblay to a man she was ill equipped to deal with - he had driven past her before, spotted that she was often alone at a bus stop. Anthony Shore recalls that day as particularly memorable.
