Need help remembering a book title

[Bobosmite]

I read a book many years ago, but the only thing I can remember is one small detail. They identified either criminals or missing people by the celebrity they looked like. Doctors/scientists discovered there was something about celebrities and brain chemestry and the police used it as a method for recognizing people...kind of like America's Most Wanted.

This CNN article http://www.cnn.com/2005/TECH/science/06/22/celebs.on.the.brain.ap/index.html triggered the memory and I wanted to read the book again.

If anyone knows the title, please let me know. I seem to have a feeling it was Philip Dick, Neil Stevenson, William Gibson...somewhere along that line or sci-fi.

That's certainly Gibson. I think it was Virtual Light, with the main character looking like Tommy Lee Jones, and a trailerpark cult of people who believed god was in television, so they watched several reruns of 70's TV at the same time 24/7.

Fantastic! Stuff like that drives me crazy and I usually end up sifting through stacks of books, late into the night. Thanks.
