I was thinking about that last night. It doesn't seem to be a property related to the Thorburns - here's the article to refresh my memory! Also on this link, at the bottom, is a timeline of the Tia case.
EDIT: Now I'm not sure if this is what you were referring to; I'm not sure about an African family, this says it was vacant. I'm a bit confused as to which property this is now...
