Your link is a bit confusing. The one image of the small TT was your friends', correct? Not the image with the headline that the couple died?
Either way, it's a scary thing. I try to remember this every time I light my stove, oven, fridge, water heater. But it's easy to miss a sign if you're operating on habit (like those times you got to work and didn't remember going past a familiar sign or building).
I hope your friends are OK.
