They scented him to the spring rd. I read that the scent went west , then it went east to spring rd where they could not find another scent.
That is the most recent scent . I know they said that he has played in that area before so ,it is possible it is an older scent. Either way ,I think the scent trail is important .
I wondered if they scented his sister scent as well to see if the dog picked her up at the same location. If not they should have scented the other two people in the house.
Any direction little Malik Drummond may have gone off by himself, in all four directions from his house, there are numerous business that would have security cameras. If there is any reason to believe he may have been taken as some are starting to believe, the timing is pretty precise as to when it that may have happened as well. I hope they're taking a look at the security cam footage from those businesses for any leads.
