Cecil and Harvey used to be good friends, but one day Harvey was found shot to death in Cecil’s garden. Cecil was holding a gun when he was found—a gun registered in his own name. When tested for fingerprints, Cecil’s matched a set found on the gun. Two sets of footprints were found in the garden soil. An autopsy confirmed Harvey died from a single gunshot wound and that he had several thin strands of fabric under his fingernail and traces of wine in his stomach. Which of the following would be considered an individual characteristic in analyzing evidence?

A.
Finding that the bullet that killed Harvey was fired from his own gun

B.
Finding that two blood stains found at the scene of a crime are both type AB+

C.
Finding that the shot that killed Harvey was taken from a one foot distance

D.
All of the above.
