Excerpt: Investigation Discovery contacted top criminal profiler Pat Brown today and asked her to share her thoughts on how yesterday's discovery of child skeletal remains will affect Casey Anthony's cooperation in the case, if those remains are identified as that of Anthony's missing two-year-old daughter, Caylee.

"Casey Anthony, since she exhibits psychopathological behaviors and has a history of pathological lying, can be expected to change her story as is necessary to be of fullest benefit to her own survival," Brown said.
