OPINION
Pеtitioner Darick Demorris Walker was convicted by a Virginia state court jury of capital murder for the killings of Stanley Beale and Clarence Threat, use of firearm in the commission of a felony, and two counts of burglary. He was sentenced to death on the capital murder count and to prison terms on the other counts. The Supreme Court of Virginia affirmed Walker’s conviction and death sentence on direct appeal and denied Walker’s petition for state habeas relief. The district court dismissed Walker’s federal habeas petition and declined to grant a Certificate of Appealability (COA).
I.
Stanley Beale lived with Catherine Taylor and their children, Monique, Bianca, and Sidney, in the University Terrace Apartments.
On the night of Beale’s murder, Tameria Patterson, a fourteen-year-old girl, was visiting a friend who lived in the University Terrace Apartments. Patterson testified that she saw a man she knew as “Todd” enter her friend’s apartment that night and say, “I shot him.” Patterson identified Walker in a photospread as the person who had entered the apartment and made the statement.
Approximately seven months later, on the night of June 18, 1997, Clarence Threat and Andrea Noble were sleeping in their bedroom. They were awakened by a “pop” coming from the screen door, which was followed by a knock at the door. Noble went to thе door and looked outside through a small window in the door, but did not see anyone. Twice more she heard someone knocking but did not see anyone when she looked out the window. Sometime after the third knock, the door was “kicked open.” Noble went to the living room to find a person she knew as “Paul” standing there with a gun. “Paul” pointed the gun at Noble, who backed into the bedroom. When they reached the bedroom, “Paul” hit Noble with the back of the gun and then shot Threat in the leg. “Paul” and Threat “exchanged words” and
Walker was indicted on one count of capital murder for the killings оf Beale and Threat within a three-year period in violation of Va.Code Ann. § 18.2-31.1(8) (Michie 1996), on four counts of the use of a firearm in the commission of a felony in violation of Va.Code Ann. § 18.2-53.1 (Michie 1996), and on two counts of burglary in violation of Va.Code Ann. § 18.2-90 (Michie 1996). On August 31 and September 1, 1998, Walker was tried before a jury in the Circuit Court for the City of Richmond and found guilty of all charges. He was sentenced to death for the capital murder conviction, life imprisonment for each of the burglaries, and a total of 18 years imprisonment for the firearms offenses.
On June 11, 1999, the Supreme Court of Virginia affirmed Walker’s conviction and death sentence. Walker v. Commonwealth,
On February 1, 2002, Walker filed a petition for a writ of habeas corpus in the United States District Court for the Eastern District of Virginia. The district court dismissed Walker’s petition on July 26, 2002. On September 4, 2002, the district court denied Walker’s Motion to Alter or Amend Judgment and declined to grant a Certificate of Appealability (COA). Walker now seeks to appeal.
II.
To appeal the denial of habeas relief in the district court, a prisoner must first obtain a COA. See 28 U.S.C.A. § 2253(c)(1) (West Supp.2002). The first opportunity to obtain a COA is in the district court. When “an applicant files a notice of appeal, the district judge who rendered the judgment must either issue a certificate of appealability or statе why a certificate should not issue.” Fed. R.App. Pro. 22(b)(1). In the present case, the district court denied Walker a COA. Because the requirement for a COA is jurisdictional, we may not consider the merits of Walker’s claims unless Walker has made the threshold showing required to obtain a COA. Miller-El v. Cockrell,
In his application for a COA, Walker raises three issues that were addressed by the district court. First, Walker argues that the state court’s conclusion that his trial counsel did not render ineffective assistance by failing to challenge his single trial for two murders was an objectively unreasonable application of federal law. He argues that the district court used an erroneous legal standard when it denied this claim. A COA is issued on this claim because Judge Gregory finds that reasonable jurists could debate whether the district court should have resolved this claim differently.
Second, Walker asserts that the Commonwealth failed to disclose exculpatory materials in violation of Brady v. Maryland,
III.
Walker was convicted of “[t]he willful, deliberate, and premeditated killing of more than one person within a three-year period.” Va.Code Ann. § 18.2-31.1(8). He was tried in a single trial before a single jury. Walker asserts that his conviction is invalid because his trial counsel rendered ineffective assistance by failing to challenge the constitutionality of § 18.2-31.1(8), move for separate trials on the two murders, or request a jury instruction that evidence of one murder could not be considered in determining Walker’s guilt in the other.
As stated above, to show ineffective assistance of counsel “the defendant must show that counsel’s performance was deficient ... [and] that the deficient performance prejudiced the defense.” Strickland,
To establish prejudice, a defendant “must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Strickland,
In Commonwealth v. Smith,
It was also not objectively unreasonable for the state court to conclude that there was no reasonable probability that moving for separate trials or requesting an additional jury instruction would have produced a different result. Even assuming that the trial court would have granted either motion, Walker has failed to establish prejudice. The risk created by joinder is that a jury may confuse the evidence and return a conviction against a defendant on a charge on which it would have acquitted if thе evidence had been properly segregated. See Zafiro v. United States,
Moreover, the jury instructions made it clear that each murder was a separate element that had to be proved beyond a reasonable doubt.
If you find from the evidence that the Commonwealth has proved beyond a reasonable doubt each of the above elements of the offense as charged, then you shall find the defendant guilty of capital murder.... If you find from the evidence that the Commonwealth has proved beyond a reasonable doubt that the defendant killed Clarence Threat, and that the killing was willful, deliberate and premeditated, but fail to find that the defendant killed Stanley Roger Beale, then you shall find the defendant guilty of first degree murder.... If you find from the evidence that the Commonwealth has proved beyond a reasonable doubt that the defendant killed Stanley Roger Beale, and that the kill*766 ing was willful, deliberate and premeditated, but fail to find that the defendant killed Clarence Threat, then you shall find the defendant guilty of first degree murder.... Ladies and gentleman of the jury, it’s simple. If you believe he killed both in a three year period that would meet the elements of capital murder. But, you might believe he killed one and not the other and that would be first degree murder. That would be a finding of not guilty as to one he is not guilty of.
(J.A. at 157-58.) Because the evidence for each murder was easily distinguishable and the jury was instructed to consider each murder separately, it was reasonable for the state court to conclude that under Strickland, Walker suffered no prejudice from his counsel’s failure to move for separate trials or request an additional jury instruction. Accordingly, the state court’s denial of relief on Walker’s claim of ineffective assistance of counsel at the guilt phase was not an unreasonable applicatiоn of federal law.
IV.
Walker argues that the Commonwealth failed to disclose exculpatory evidence that would have impeached the trial testimony of three of its key witnesses: Bianca Taylor, Tameria Patterson, and Chris Miller. The state court concluded that Walker’s Brady claim regarding Bianca was procedurally barred and found Walker’s Brady claims regarding Patterson and Miller without merit. (J.A. at 348-49.) We will discuss the state court’s application of the procedural bar and determination on the merits in turn.
A.
Bianca testified at trial that she saw the shooter enter the house, yell at her father, and then shoot her father. Walker contends that the Commonwealth suppressed the following evidence that indicates that Bianca did not see the shooter: the Supplementary Offense Reрort of Officer Ernst (J.A. at 537), Supplementary Offense Report of Detective Mullins (J.A. at 489), handwritten notes of Detective Mullins (J.A. at 485), and statements made by Bianca and Catherine Taylor to Detective James Hickman (J.A at 543A). The state court, applying the rule in Slayton v. Parrigan,
A federal court conducting habeas review is “precluded from reviewing the merits of a claim that was procedurally defaulted undеr an ‘independent and adequate’ state procedural rule, ‘unless the [applicant] can demonstrate cause for the default and actual prejudice as a result of the alleged violation of federal law, or demonstrate that failure to consider the claims will result in a fundamental miscarriage of justice.’ ” Fisher v. Lee,
“Cause excuses the failure to raise a claim during a state proceeding if ‘the factual or legal basis for [the] claim was not reasonably available.’” Fisher,
In applying the Slayton procedural bar, the state court found that at the time Walker filed for direct review, Walker’s counsel was aware of the factual basis of Walker’s Brady claim, specifically, the Commonwealth’s suppression of the evidence that allegedly could have impeached Bianca’s testimony. This factual finding is presumed to be correct and petitioner has the burden of rebutting the presumption of correctness by clear and convincing evidence. See 28 U.S.C. § 2254(e)(1). Walker fails to satisfy this burden. Indeed, as Walker admitted in the first habeas petition he presented to the district court, shortly before trial the defense received a Presentence Report referencing two undisclosed police reports containing the same information as the documents listed above. This Presentence Report, by referencing these undisclosed documents, evidenced the Commonwealth’s suppression of the alleged Brady material.
B.
We now turn to the remainder of Walker’s Brady claim regarding the Commonwealth’s alleged withholding of evidence that would have impeached Patterson and Miller. Patterson testified at trial that someone she knew as “Todd” entered the residence of Karen and Charles Randolph and Jennifer Stewart, an apartment at 1309 W. Graham Road, on the night of Beale’s murder and exclaimed, “I shot him.” (J.A. at 50-52.) Miller testified that he observed an unidentified person leave Beale’s apartment after the shooting and enter the Randolph apartment. Walker contends that the Commonwealth suppressed the following records that would have impeached the testimony of Miller and Patterson: (1) a handwritten note by Detective Mullins recоrding Karen Randolph’s statement that “Ty didn’t come into her apt. [1309 W. Graham Road] after the shooting”
The state court concluded that this portion of Walker’s Brady claim was without merit. Speсifically, the state court concluded that “no material, exculpatory evidence was withheld.” (J.A. at 348.) The state court reasoned that
[n]either Stewart nor Randolph testified at trial; a review of the investigating officer’s complete notes indicates that Christopher Miller would not have been impeached since he told the officer that he saw a person walk from the Taylor apartment and enter the Randolph apartment. Randolph would have placed Walker at the murder scene regardless of whether she would have testified that he did or did not enter her apartment, thereby destroying the exculpatory quality of the evidence alleged by petitioner to have been withheld.
(J.A. at 349.)
Under the Brady rule, the prosecution is required “to disclose evidence favorablе to the accused that, if suppressed, would deprive the defendant of a fair trial.” United States v. Bagley,
First, Randolph’s statements to Detective Mullins that “Ty didn’t come into her [1309 W. Graham Road apartment] after the shooting” (J.A. at 486) cannot be characterized as impeachment evidence because Randolph did not testify. Moreover, even if it were potentially exсulpatory evidence, it would not fall under the Brady rule because Walker’s defense counsel was aware before trial of the fact that Randolph did not see Ty enter her apartment after the shooting. Information known by the defense falls outside of the Brady rule. See, e.g., United States v. Agurs,
Second, Stewart’s statement to Detective Mullins that she “didn’t see [Todd] Friday evening” at 1309 W. Graham Road (J.A. at 486) also cannot be characterized as impeachment evidence because Stewart did not testify. Moreover, Stewart’s statement is not favorable to Walker because it does not contradict Patterson’s claim that she saw Walker enter the apartment. Patterson testified that she had been upstairs with Stewart and that she saw Walker as she was coming down the stairs. Patterson did not say whether Stewart was coming down the stairs with her and thus gave no indication that Stewart was also in a position to see Walker.
Finally, Walker claims that the following three documents contradict Miller’s testimony that the person Miller saw leave Beale’s apartment entered the Randolph apartment before driving away: the Commonwealth’s witness synopsis sheet (J.A. at 483), the Supplementary Offense Report of Detective Mullins (J.A. at 488-89), and Supplementary Offense Report of Officer Ernst (J.A. at 537). The witness synopsis sheet was created by the prosecution to summarize statements by the witnesses. The statement recorded on the witness synopsis sheet, that the person Miller observed the night of the shooting “didn’t go in” 1309 W. Graham Road (J.A. at 483), contradicts Miller’s testimony that the person he saw leave Beale’s apartment entered the Randolph apartment before driving away. Even if Brady requires a prosecutor to disclose work product,
V.
Walker also seeks to assert that his execution would violate the Eighth Amendment under Atkins v. Virginia,
VI.
In summary, we grant a COA as to Walker’s claim that his Sixth Amendment right to counsel was violated at the guilt phase of his trial and his claim that his due process rights were violated when the Commonwealth failed to timely disclose Brady materials. Because we conclude that the resolution of these issues by the Supreme Court of Virginia does not constitute an unreasonable application of clearly established federal law, we affirm the district court’s dismissal of these claims. We deny a COA and dismiss Walker’s appeal with regard to his claim that his Sixth Amendment rights were violated at the sentencing phase of his trial because reasonable jurists could not debate the district court’s resolution of that issue.
