16.  Earlier, the statistician bristled at a suggestion from the defense that his complicated calculations on genetic matches would be meaningless if laboratories messed up.

17.  Investigators are now checking hundreds of unsolved missing person cases to try to find a genetic match, a police official said on condition of anonymity.
