I often wonder about some of these rule outs, especially if DNA or dental aren't available and yet the person is ruled out. Makes me wonder what criteria they use sometimes.
Also, I had a question if anyone knows. Can isotopes tell how old a filling is? Man I wish I had been a forensic dentist. That just seems so fascinating to me.
I don't know about isotopes, but dentists know plenty about fillings just by looking at 'em. Two different dentists have correctly identified my oldest filling. I expect that the material used did change over time, and a dentist can at least bracket the age of a filling by the appearance of the material used?
Dental professionals, please chime in here!!!
(I agree on the detail-free rule-outs, Alleykins.)
