Just like the whole case. The REAL evidence is either IGNORED or DESTROYED.
Police: "Gee, her PJ's are lying here on the floor. There are SPARKLIES on the floor, but the NEW OUTFIT she just bought is missing. Therefore I conclude she was wearing her PJ's when she was kidnapped from this bedroom."
So Danielle presumabley was wearing pajamas that shed these "sparklies" during her abduction?
