Update from Tuesday, 22 October 21:45, with other information from previous days lower down in the article:
Der Mörder des getöteten Fabian (8) aus Güstrow ist noch immer nicht gefasst. Vor kurzem durchsuchte die Polizei ein Anwesen in der Nähe des Fundorts.

First they explain why search dogs alerted to something in the lake (Inselsee) as opposed to the pond. There were 17 search dogs involved and several of them alerted to a scent in the lake. They're trained to look for the scent of decomposition in water, and since somebody had drowned in that lake a month or so before, that's probably what they were alerting on. Apparently if there's a dead animal in the water, they might alert on that too.
Next, there will be another church service for the grieving town and Fabian's family on Thursday, because it's deemed important, it's also a thank-you service for all who have helped in the search or supported the family so far. Especially the family wishes this, to show their gratitude to the local community. Emails and postcards which were sent to the town (or the family presumably) in support will be read out loud during the service.
Fabian's body has been returned to his family. They will have a private funeral service at a later date.
So far police are only saying that Fabian died a violent death, but they're not saying how so as not to impinge on the investigation. However they are also saying that there is no danger to the general public.
There are people in the village of Reimershagen (where the farm is) who claim that Fabian used often to play in the village since his father was in a relationship with a woman in the village. Police don't mention this at all.
@ChatteringBirds Is this the kind of information you picked up in relation to the farm? I know I read it or heard it on other media in the last few days.
A detective called Axel Petermann mentions that it is not known whether Fabian took anything with him from home or whether any of his clothing was missing - so it could be anything of that nature that the police were looking for on the farm.
