Thinking out of the box here and could be completely, utterly wrong, but my inclination is that the “cleaning lady” is a Muslim....
Either that or a drunk Swede. There are a few of those.
I think I read that she was only 21. She could have just had an “I’ve always wanted to drive one of these” moment. Think about the teenage boy, works in the stockroom... he gets a chance to get into the warehouse, and there is a forklift sitting there, no one around... wants to try it out. Could just be a bad decision due to immaturity and curiousity.
