Apparently radioactive medical waste has been stolen in Mexico, something similar to what happened in Brazil in 1989. 4 people died in the Goiana incident after medical waste was stolen and played around with in the scrapyards where the contents were opened. Here, it looks like the thiefs only wanted the truck, not knowing the contents of the truck. Hopefully they decide not to play with the contents.
