I grew up in Western Iowa, and I spent lots of time in the summers with my grandfather who drove a truck hauling grain and livestock. My father worked on a hog confinement for few years and during the summers I frequently tagged along with him. There are a few topics that I have seen here that stand out to me.
But first, here is a little bit of background about hog confinements. This may not all be correct for each operation, but this is how the ones I've experienced work:
- Farrowing Barns -- This is where the piglets are still with their mother. They are not weaned yet and they piglets are still very small.
- Starter Barns -- The first barn they are moved to after they are weaned from their mothers. They are roughly 15lbs and moving them is still fairly easy.
- Finishing Barns -- Depending on the size of the operation there may be another barn between the starter and finishing barns, but this is where the hogs go to get up to weight before they are sent to the processing plant. Moving them at this stage is most difficult because they weigh 250+ pounds, they are physically strong, and most of them are cranky from living in a pen with a bunch of slobs. There are always some sweethearts in the building that are friendly and get moved to a pen to get spoiled, but that's not relevant here XD.
Topics of concern:
1. He may not have needed coveralls. His coveralls and boots missing from the truck may or may not be a big deal. I haven't seen if the barn he was picking up from was a Farrowing barn or a Starter barn. The farrowing barns don't really require coveralls since the piglets are still so small. At this point, the boots are to keep poop off and to keep from getting bit. Farrowing and Starter barns are not nearly as dangerous as Finishing barns, but I wouldn't say that moving hogs from Starter > Finishing barns is not overly dangerous. Most confinements have a hose just outside the door so boots can be sprayed off. He may have chosen to not wear coveralls, and he may have just sprayed off his boots and hopped into the cab of the truck because he was in a hurry. Not uncommon. With that being said, if he did wear coveralls and boots then that is concerning because from what I know they have not been recovered. I wouldn't be surprised either way.
2. Someone should have been waiting. When moving livestock there is typically a lot of communication between the driver and whoever is receiving the load. I remember many late nights in the summer waiting for a driver to show up to pick up or drop off a load. Someone should have been waiting for him to arrive at their facility with the piglets. I don't know of any operations that would just allow the driver to unload the hogs without any assistance from staff. There is a bit of work involved with this process, unless the facility had some type of overnight holding pen, which I have never seen. However, that does not mean they don't exist.
3. Driving a semi-truck is not easy. A semi for hauling livestock is not something just anybody can hop in and operate. I can slowly move one down the road if needed, but progressing through the gears takes a bit of practice. If someone did move his truck they most likely have experience driving a rig.
4. Lagoons. Most large confinement operations have holding ponds, or lagoons, that hold the waste produced by the hogs in the buildings. In the spring, the lagoons are pumped out and tilled into the surrounding fields for fertilizer. In my experience, there is almost always a collection of dead animals that wandered to close to the edge and slid down into the lagoon. The lagoons are lined with tarps that are slippery and make it nearly impossible to climb out. I would imagine that searching those lagoons at this time of year would be nearly impossible due to the amount of waste and the thickness of the half frozen poop slurry. The farmer won't want to pump the lagoons dry at this time of year, lest they waste a lot of money and fertilizer for the upcoming spring.
5. Drugs. I know that DS does not have a reputation for drug use, and I hate making assumptions, but Meth is very prevalent here in the trucking industry. I would say the vast majority of truck drivers DO NOT use, but it would not surprise anyone around here to find out that a truck driver was using. It can be out of the body and undetected by testing within a couple days which makes it the safest option if subject to random DOT testing. If he was working all hours of the night after a full day of working, that seems a little methy to me. My old man used for most of my childhood. Doing drugs doesn't mean that anything bad should happen to the user, but that crowd of people can be extremely unpredictable and desperate.
I am just as flabbergasted as everyone else here; but if I were an investigator with no leads I would focus on his coveralls/boots, find the people at the barns that can drive a big rig, search the lagoons, and try to verify no history of meth use.
This is all JMO.
