The following excerpt is from Johnson v., No. 2:14-cv-643-KJM-EFB P (E.D. Cal. 2017):
It is within the broad range of professionally competent assistance to choose not to investigate evidence which would contradict the primary defense theory. Corell v. Stewart, 137 F.3d 1404, 1411 (9th Cir. 1998). Put another way, once counsel reasonably chose one defense theory, her duty to investigate another conflicting defense was at an end. See Strickland, 466 U.S. at 691.
