MEMORANDUM
Gerald Lester, a California state prisoner, appeals pro se the district court’s denial of his habeas petition filed pursuant to 28 U.S.C. § 2254. He contends his trial and appellate attorneys rendered constitutionally ineffective assistance of counsel. We reject that contention and we affirm.
DISCUSSION
We review de novo the district court’s decision to deny Lester’s habeas petition. See Polk v. Sandoval,
Lester contends his trial counsel was ineffective for not adequately impeaching the pathologist regarding the time of death of the murder victims. We agree with the district court that even if counsel had pursued an additional theory of impeachment, Lester failed to demonstrate prejudice. The record indicates his counsel was able to impeach the pathologist to the point the doctor admitted he changed his opinion regarding the time of death, that there remained “a lot of uncertainty,” and that “it would just be completely wrong and foolish for me to say that death clearly occurred on the 5th.” Given this degree of successful impeachment, it is clear that the additional impeachment urged by Lester would not have changed the result of the proceedings. See Strickland,
Lester argues his appellate counsel was ineffective for failing to raise a speedy trial claim. Much of the delay here, however, was caused by the state court’s decision to join defendants, a decision the federal district court concluded was “based on sound reasons of judicial economy” such as “the overlap in witnesses, discovery, and other trial-related matters.” Further, there is no question this was a complicated, multiple-murder case with a great deal of evidence that required substantial time to prepare. Finally, Lester does not make a credible argument that the outcome of
Lester also contends his appellate counsel should have investigated a report that the prosecution had impermissibly contacted a juror’s co-worker about the case. Lester did not submit any evidence, however, that any juror received extrinsic evidence or was not impartial. The district court properly denied his request for an evidentiary hearing because he did not demonstrate his claim relied on facts “that could not have been previously discovered through the exercise of due diligence.” 28 U.S.C. § 2254(e)(2). The “failure to investigate or develop a claim given knowledge of the information ... is not the exercise of diligence.” Cooper-Smith v. Palmateer,
Finally, we do not reach the merits of the several uncertified claims Lester raises in his opening brief. He did not make the requisite “substantial showing of the denial of a constitutional right” that would permit us to expand the Certificate of Appealability. See Doe v. Woodford,
AFFIRMED.
