Whoever did this obviously had some farmers knowledge, and also a farmers´ mind: They did not harm any of the animals, not even the dog (until the very last day) though it must have been a hazard.
The use of the pickaxe as the murder weapon also points towards this: The victims had been hit with precision and a lot of hatred, their heads had been split but their bodies had apparently not been hit. Whoever did this must have been familiar enough with using a pickaxe to do so without thinking.
Whoever did this also must have been known on the farm, as the Grubers´ dog â€" a Pomeranian, said to be a keen watchdog â€" was first heard inside the house, but and later seen tied up and healthy, barking like crazy outside the barn by a mechanic who came to the farm on Monday. The dog was found inside the barn, hurt and frightened, by the men who discovered the dead on Tuesday. So the killer was familiar enough to the dog to be able to handle it during the three days he stayed on the farm after the murders.
