The way the police spoke of it, it sounded like the people had claimed it with no evidence, but given that 3 different, unconnected people had said it, the police had looked into it.
The latest report was saying the sniffer dog had located other areas inside and outside the house to look at, and the police don't know if it's more bodies, or other bits of the first one.
