I'm not sure what's unusual about this. Fires at night are dangerous because people sleep so they're more likely to be caught by surprise when the fire is already completely out of control.
All it takes is an electrical spark, a candle they forgot to put out, a heater too close to some fabric and you got yourself a fire.
Frankly this internet sleuthing is rather pointless and, in my opinion, in rather bad taste.
stop. just stop speculating. you have the news article, that's it. you know nothing. this is not helpful, it's not interesting, you're not doing anything productive. this is wrong and it's sick.
If there was a fire elsewhere in my house while I was in my bedroom and I didn't notice (because I was sleeping or otherwise), its highly likely I'd be trapped too, depending on where the fire started. If fire is between me and an exit, then I'm trapped.
While the article doesn't say he was sleeping, it also doesn't say he wasn't. You can't assume either way, but you seem to be assuming that because it doesn't say, it means he wasn't.
No, it doesn't imply anything. What if you fall asleep in the basement? What if part of the house collapses and can't be accessed? Is that a "blockade"?
