What is the standard of conduct of a defense lawyer in a sexual assault case?

Petitioner alleges that any defense investigation Hoover did conduct was untimely and insufficient to develop relevant facts. (See Doc. No. 321 at 16-23, 80-104, citing the ABA Standards 4-4.1 [2d ed. 1982 Supp.]); see also Rompilla v. Beard, 545 U.S. 374, 387 (2005) (citing 1 ABA Standards 4-4.1) ("[I]t is the duty of the lawyer to conduct a prompt investigation of the circumstances of the case and to explore all avenues leading to facts relevant to the merits of the case and the penalty in the event of conviction.").
