Do you think Avon police should keep quiet until they actually know something useful?

just looked up the crime in Bristol. pretty high rate for half mil people. what does the police do in that area? pizza is gone and the sock could be in the hamper. maybe she didn't get to take both off and answered the door. it amazes me that the police hasn't solved it yet. how many people could have she opened the door to at 9 pm??? she wasn't alive when they got her out the door. Jefferies saw it and he knows the killers. that might made him a suspect. who is he afraid of???
