She is a psychopath in a different way. She cares less for another, than herself.....she may have been involved.
Noticed a report that said the officer looked around to see if he could see a spot on the floor where he hit his head and he couldnt. Head wounds bleed a lot. Usually where ever a person falls and they get up they will leave a mark where they hit. Most people planning murder have not done it enough to know all the things a detective sees that stick out like a soar thumb. Watching CSI wont help. Also police officers have been on scenes where family members have been hurt and they can gauge when someone is just phoning it in. We will see how this plays out...
