Felix Salmon has put together several examples like this one:
In their investigation into the art theft, [officials] found that Mr. Istavrioglou had searched the Internet for reports about the robbery after it took place but before the story became news.
Reminded me of this ancient post; the underlying story, unfortunately, is lost to link-rot.
[Update: Apparently, there's a category of crimes called Google Murder Cases. Grim stuff.
The link-rotted 2005 story has also been reported on elsewhere.]
