See the little white flower in her hair in the 7 News picture and the same flower in her hair when she attended the memorial for "Martin".

Her presence at the Marathon was required because she is too young to be a fraud. She was absent from the promotion of the fraud until the memorial; ? pre-planned surgery after the Marathon.
