The only way I can make that scenario work is if she was fronted drugs and later claimed they were "stolen", so she couldn't pay her supplier.
The only reason I would even entertain that scenario is because I watched an episode of the FBI Files the other night in which a guy claimed $20K of pot was stolen, and the dealer kidnapped and murdered his wife and young son.
also the movie "gone baby gone" had this scenario. although that was nto what really happened to the baby at the end
