For a search warrant you need probable cause which is either signed by a judge or a magistrate judge. Now why they are not naming them "persons of interest" that I don't know. I know that I do want evidence to lay before them during the interview to obtain a confession. They know exactly where they are at and if anything is found to add on to the evidence that they have, which seems little, if any, then they will be brought back from up north. Lot's of evidence can come from this search such as tire impressions from the 4 wheelers, blood stains, which I doubt they would get or weapons, another doubtful aquirement, or even a lost phone. I am sure all of the social media that anyone that is in their mind a suspect has already been searched as they never go away. A lot or nothing could come from this. One other thing that could come from this if any shoes were left in the trailers. I am sure that shoe prints had to be left at one of the scenes from all of the blood, maybe at CR1 or blood splatter. Another thought crossed my mind what about an enraged grand parent. I wished that they had conducted more of a ground search of the area for areas that they would shoot on the property looking for any kind of shells or rounds. That would really sink them. I hope I am within the frame of not breaking TOS.
