Stealing Money

I can't even imagine a criminal case happening around me. A colleague, who was a really nice person, got into a car accident and broke his ribs, ending up hospitalized. The company keys weren't recovered in time. We heard he'd be discharged and back by the end of the month, and everyone was happy and waiting for him. Unexpectedly, the next news we heard was that company money was stolen. When we checked the surveillance, it turned out to be that colleague. Apparently, he borrowed from loan sharks. We don't know when he was discharged, but he used the keys to open the door and steal the money. I just want to say, I don't understand why he didn't sue the boss first for not having labor and health insurance, only group insurance. If he couldn't win the lawsuit, then he could borrow, although our boss is so despicable, I doubt he wouldn't win. But I heard he also has diabetes or something, which I guess isn't covered by insurance? If he was really desperate for money, I guess I could understand, though I'm curious where he found loan sharks, a place that wouldn't be near me at all.
