I don't think blood was planted, I just have not heard confirmation that the blood on his jacket and in the motor home is the girl's.
BTW, the dog's going to his house is easily explained by the cookie sales
No, the dogs went to 127 different locations in the neighbourhood. In my opinion, that indicates the child had gone about the neighbourhood as any kid would, but, absent any direct path detected by the dogs, she must have been taken away in a vehicle very close the house. Of course my info could be wrong or biased.
As for confirmation on the blood being the girl's, at first LEO tested mitochondrial DNA (meaning the DNA matched the mother and her offspring alone). Now that the body has been found and more thorough tests can be conducted, the truth of the physical evidence will all be determined. We have only to be patient on this issue.
Best regards, wonders
One article in the SD Union-Tribune noted that the dogs went to every house in the neighborhood--some sum over 160, I don't recall the exact amount. Like you say, cookie sales.
