Piecing things together
CBI investigator Tom Griffin took the 13 bullet fragments to determine whether they could be linked to any of the .22-caliber guns that were at the scene when Jill died. After a series of tests, it was determined that the fragments were not from a bullet fired from any of the guns used by Jill and Tanner. Mike’s lever-action rifle “could have fired” the shot that killed Jill.
