Several months ago, Riverrat started a thread about a beekeeping family, in Kansas, that had a trailer loaded with hives and the trailer was stolen. I ran into the wife at a state beekeeping meeting. They found strewn hives dotted across the country side. Obviously, the trailer was what the thieves wanted. She expressed frustration with the Barney Phyfe style of police work and they have written it off as a loss.
In the case of the Sioux City beekeepers, I did read that the police will continue to investigate. I also read that the couple did have a trail camera in place. The vandal(s) destroyed or stole it as well.
I feel for these people.
