A freak accident occurring because of a complete failure to think about safety first. Listen to what they're saying. She climbed a dresser to lean over the top of a six foot bookshelf to adjust some TV wires. What part of this sounds like a good idea to someone? She fell six feet onto her head in an enclosed space.

Also, Desert Rat has a point. It seems that these days, nobody pays attention to screams or call's for help. We seem trained to mind our own business entirely too well. Maybe it's because TVs, Radios, and video games are so constantly bombarding us with the sounds of chaos that we've become oblivious.
