Maybe it is a different family?
It was an older man and his wife. She died due to lung problems while they were in the pool as the flames spread over them. I did not click on you link yet, but I read the story I am relaying on SF Gate yesterday.
Yes, different story. I will see if that story is still available.

Here is that sad story I was relaying
I’m watching the local news & they also reported that the couple did survive. Perhaps that was another couple like you said.
