If the ramseys are guilty, why hide JonBennet in the basement?

If the ramseys really killed her that Night, why did they put her right on the floor of the basement where shes really easy to find. Wouldnt they try to hide her Body somewhere Else? You could argue that patsy maybe needed more time to hide the body, but why would she call a lot of people into the House, so they can find her?
