I spoke with my cousins who are a lawyer and a Detective. We do not live in MO, so not sure if the rules are different. But, here they would have gotten a warrant right away. They had probable cause to search the house.
What frightened all three of us, and I am sure many of you, is she could have been alive or close to dying in the house as they sat outside waiting for her. What if he had poisoned her or locked her in a box and she was gasping for air? I also am not understanding they then walked in without a wart pant to see if anyone needed help? Why not do that when they arrived? I am not faulting them in their process for bring ping her home because I am greatly impressed in how quick this way. But, I do not understand why it took until 2am to get a warrant. You can get a warrant signed here in minutes, even in the middle of the night. I just wonder if there is more behind the details that they are not telling because otherwise it makes little sense.
