If you go to 31:17 of the Crimewatch report then you have an image of what I assume is her bedroom. You can see no curtains and smoke damage up the one window. Without lining everything up, I assume the passer by has seen the flames from here. It's interesting how isolating the fire was from this image also. Nearby furniture undamaged, even clothes just with smoke damage. It looks like a fire was started in the middle of the furniture by the window, whether that is a bed or sofa I am unable to tell.@ 27:05
