The three suspects are reported as being burglars who were in the area and whose phones were very active. If so, that is not much. Burglars aren't in the business of abducting or murdering small children. And it is no surprise if their phones are active when they are working. They would use phones to tell each other who was in, who was out, where the buildings concerned were, what security was like, who was about, whether there was a dog , and other useful information to their gang, all of this activity being intense at the time before and after a hit.
