In addition, our cases have long held that it is the prerogative of the finder of fact to accept or reject expert testimony and to select which parts of the witnesses' testimony to believe or disbelieve. See, e.g., Gutierrez v. Albertsons, Inc., 113 N.M. 256, 261-62, 824 P.2d 1058, 1063-64 (Ct.App. 1991) (indicating that the fact finder may select which portions of the witnesses' testimony to believe, provided that the fact finder may not fragment the testimony to the point of distortion); Sanchez v. Molycorp, Inc., 103 N.M. 148, 153, 703 P.2d 925, 930 (Ct.App. 1985) ("[T]he opinions of an expert even where uncontradicted, are not conclusive on facts in issue and the fact finder may reject such opinion in whole or in part.").
