Petitioner Terrance A. James was convicted of first degree murder in OMahoma state court and sentenced to death. The OMahoma Court of Criminal Appeals affirmed the conviction and sentence,
see James v. State,
Mr. James filed his initial habeas corpus petition on July 1, 1992. Pursuant to his motion, the federal district court held the habeas proceedings in abeyance pending a decision in a somewhat related 28 U.S.C. § 2255 motion challenging a federal sentence he had received for theft of government property. The district court reopened the case on October 5, 1994, following this court’s affirmance of the denial of § 2255 relief. After appointment of new counsel, Mr. James filed an amended habeas petition. The district court denied *549 habeas relief, but granted a certificate of probable cause on all issues. We affirm the district court’s denial of federal habe-as corpus relief.
I.
Mr. James, Dennis Brown, and Mark Allen Berry, codefendants in a federal case involving theft of government property, were incarcerated in the Muskogee City/Federal Jail. All three had pled guilty. Mr. James and Mr. Brown believed that Mr. Berry had snitched on them and was responsible for their arrest. As they discussed what to do to Mr. Berry, an inmate named Sammy Van Wouden-berg joined in the discussion and encouraged the two to strangle Mr. Berry with a wire from a broom and then hang him to make it look like a suicide. Mr. James and Mr. Brown planned to strangle Mr. Berry while Mr. Van Woudenberg acted as a lookout.
Early the next morning, Mr. Van Woud-enberg placed a piece of paper over the lens of a surveillance camera and returned to his cell. Mr. Brown asked Mr. Berry to play cards. While the two were playing, Mr. James approached Mr. Berry from behind and wrapped the wire around his neck, strangling him while Mr. Brown held Mr. Berry’s feet and placed his hand over Mr. Berry’s mouth. Mr. Van Woudenberg warned Mr. James and Mr. Brown that someone was coming. Mr. James dragged Mr. Berry into a cell and continued strangling him. After his body went limp, the three hung Mr. Berry’s body in a shower stall.
Mr. James and Mr. Van Woudenberg were charged with and tried together for the murder. 1 Mr. James testified at both stages of trial. At the guilt stage, he admitted that he discussed killing Mr. Berry, strangled him with a wire, dragged his body into a cell and continued to strangle him, and then helped hang the body in the shower. The jury rejected Mr. James’ defense of intoxication and found him guilty of first degree murder. At the second stage of trial, Mr. James presented mitigating evidence of his remorse, his troubled childhood, and his use of drugs. The state presented evidence of three aggravating circumstances: the murder was committed while Mr. James was imprisoned on conviction of a felony; he would be a continuing threat to society; and the murder was especially heinous, atrocious, or cruel. The jury found all three aggra-vators and fixed punishment at death. 2
On appeal from the district court’s denial of habeas, Mr. James asserts the following constitutional issues he believes entitle him to relief: (1) the trial court used an unconstitutional burden of proof at the competency hearing; (2) under
Ake v. Oklahoma,
II.
Because the original habeas petition was filed before the effective date of the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), AEDPA’s standards do not apply to this appeal.
See Lindh v. Murphy,
A. UNCONSTITUTIONAL BURDEN OF PROOF AT COMPETENCY HEARING
Mr. James first contends the trial court denied him procedural due process by applying at his competency hearing the “clear and convincing” evidence burden of proof found unconstitutional in
Cooper v. Oklahoma, 517
U.S. 348,
Mr. James attempted to raise this claim in a pro se second post-conviction application. The Oklahoma Court of Criminal Appeals refused to accept the pro se filing because Mr. James was represented by an attorney and the attorney was required to submit the argument, see Okla. Stat. tit. 22, ch. 18, app., Rule 3.4(E). Although the court dismissed the application without prejudice, Mr. James did not attempt to refile with proper submission by an attorney. Thus, the state contends, the claim was not exhausted.
Exhaustion is not required if an attempt to exhaust would be futile.
See Clayton v. Gibson,
Even if failure to exhaust is excused, however, procedural competency claims may otherwise be procedurally barred.
See Rogers v. Gibson,
The 1995 Oklahoma statutory amendments “greatly circumscribed” the
*551
court’s power to apply intervening changes in the law to post-conviction applicants.
Valdez v. State,
In order to prevail on a procedural competency claim, a petitioner must establish a ‘“bona fide doubt as to his competency’ ” at the time of trial.
Wallace,
The record does not persuade us there was a bona fide doubt regarding Mr. James’ competence to stand trial. The defense’s own witness, Dr. Garcia, testified that he had observed and evaluated Mr. James over a seventeen day period during which Mr. James was a patient at Eastern State Hospital. Dr. Garcia observed no organic brain syndrome at the time and diagnosed Mr. James with a schizoid personality disorder which only slightly affected his decision making ability. In Dr. Garcia’s opinion, Mr. James was competent, able to comprehend the nature of the charges and proceedings against him, and capable of assisting his legal defense. Based on Dr. Garcia’s testimony, the trial court found Mr. James competent. Dr. Ruedi, who did not testify but who examined Mr. James for competency, also concluded he had an adequate factual and rational understanding of the charges and the possible outcome of a guilty verdict, could assist in the preparation of his defense, and was competent.
There was no evidence that Mr. James’ competency changed from the time of the competency hearing to the time of trial, at which he testified during both stages.
See Drope v. Missouri,
B. PSYCHIATRIC ASSISTANCE
Mr. James relies on
Ake v. Oklahoma,
On direct appeal, the Oklahoma Court of Criminal Appeals addressed this issue only as to the first stage, although Mr. James raised it as to both stages. The court determined Mr. James’ case was distinguishable from
Ake
because he failed to demonstrate to the trial judge that his sanity at the time of the offense would be a significant factor at trial, instead relying on the contention he was under the influence of drugs at the time of the offense.
See James,
Mr. James first contends he did make a request for psychiatric assistance, but it was turned down by the trial court. Mr. James’ 'trial counsel testified at the post-conviction evidentiary hearing that he talked to the trial judge ex parte about obtaining expert assistance, but he did not file a formal motion because there was no legal entitlement to an expert prior to Ake. Because it was futile to make such a motion, we assume counsel’s ex parte request was sufficient.
In a case siich as this where
Ake
was not available at trial but was available at the time of direct appeal, the proper standard to determine whether a petitioner is entitled to psychiatric assistance is whether he could have made a showing that his sanity or mental state at the time of the offense would be a significant factor at trial.
See Castro v. Oklahoma,
We analyze this issue by looking at the evidence available both at the
*553
time of trial and thereafter.
See Moore
v.
Reynolds,
Oklahoma follows the M’Naghten test of legal insanity, requiring the defendant to show that at the time of the crime he suffered from “a mental disease or defect rendering him unable to differentiate between right and wrong, or unable to understand the nature and consequences of his actions.”
Jones v. State,
Mr. James’ application for determination of competency did not indicate that sanity would be an issue. His medical records from Eastern State Hospital, where he was admitted for a competency evaluation, do not indicate he was insane at the time of the murder. Dr. Garcia, who examined Mr. James for competency, did not find him incompetent to stand trial, nor did he mention any issue regarding sanity. Dr. Ruedi, a clinical psychologist, noted Mr. James had difficulty concentrating and tremulousness consistent with withdrawal from substances. She also concluded Mr. James was competent to stand trial.
Dr. Rice, a defense expert witness, testified that the ingestion of the particular drugs could have caused Mr. James to remain conscious with impaired thought processes, judgment, and motor coordination. However, three State’s witnesses testified that at the time of the murder Mr. James was not stumbling or staggering, did not have slurred speech, and did not appear to be intoxicated by drugs. Moreover, this testimony regarding intoxication is not relevant to Mr. James’ sanity.
Nor does the new evidence available after trial assist Mr. James with respect to this claim. Although he testified at trial that he did not remember much of the murder because of his intoxication, he later testified at the post-conviction evidentiary hearing that he did not black out during the murder and that he knew what happened but was not in control of his mind. Trial counsel testified at the post-conviction hearing that he did not raise an insanity defense based on Dr. Garcia’s opinion that Mr. James did not have organic brain syndrome. Counsel testified it would have been helpful to have had a psychiatric expert (apparently in addition to Dr. Rice) testify on Mr. James’ behalf, but did not indicate in retrospect that he would have raised an insanity defense.
An affidavit of Dr. Phillip Murphy, Ph. D., prepared more than nine years after the murder, indicated there was “reason to believe” Mr. James suffered from brain damage at the time of the crime, had significant intellectual deterioration and memory disorder, and had temporal lobe epilepsy while under the influence of drugs. Dr. Murphy believed there was “evidence” Mr. James was under the influence of drugs at the time of the murder and because of “possible” brain damage was unable to comprehend his actions totally. Dr. Murphy also believed a full neuropsychological evaluation would provide evidence indicating whether the brain damage could have influenced Mr. James’ *554 culpability for the crime. Dr. Murphy’s carefully worded affidavit does not create a serious doubt regarding Mr. James’ sanity at the time of the murder more than nine years earlier.
A deposition of Joy Carol Lee Keithley, Mr. James’ ex-mother-in-law, indicated that the day after the murder his words were slurred and she could not understand what he was saying. She believed he acted as if he was on drugs. This is not persuasive evidence in light of Dr. Murphy’s testimony that Mr. James would have been under the influence of the drugs for approximately thirteen hours. Ms. Keithley talked with Mr. James more than twenty-four hours after he took the medication, so his alleged state of intoxication at that time is not relevant.
Considering all of the evidence, we do not believe Mr. James could have made a showing that insanity or his mental state would be a significant factor at the first stage of trial. Consequently, he was not entitled to expert assistance at the guilt stage. ■
In order to be entitled to appointment of a psychiatric expert at the sentencing phase, Mr. James must establish his mental condition was likely to be a significant mitigating factor.
See Rogers,
Mr. James’ second stage defense did not rely on mental health evidence. Rather, he presented evidence of his remorse, his troubled childhood, his prior use of drugs, and Mr. Van Woudenberg’s influence on him. Trial counsel testified at the post-conviction evidentiary hearing that his strategy did not include introduction of mental health evidence because there was no evidence Mr. James suffered from organic brain syndrome at the time of the murder. 5 Dr. Murphy’s affidavit did not address whether Mr. James would be a continuing threat. We hold that Mr. James has failed to meet the threshold showing his mental condition could have been a significant factor at sentencing.
.Even if Mr. James was entitled to psychiatric assistance, failure to provide that assistance is subject to harmless error analysis.
See id.; Castro,
Any error with respect to the first stage of Mr. James’ trial is harmless because no evidence suggested he could have asserted an insanity defense. In the second stage, the jury was presented with evidence of the callous nature of the murder as well as Mr. James’ threats, possession of a weapon, and felony conviction. At best, a psychiatric expert may have testified to the possibility that Mr. James may have suffered from some type of neurological dysfunction that may have impaired his judgment. However, none of the doctors who examined Mr. James at the time of trial came to this conclusion, even those secured by the defense. We are not left with significant doubt that this potential evidence would have outweighed *555 the significant evidence in support of the continuing threat aggravator such that even one juror would have voted against imposing the death sentence.
C. LESSER INCLUDED OFFENSE INSTRUCTIONS
Mr. James cites
Beck v. Alabama,
Mr. James also argues that Oklahoma decisional law required the trial court to instruct the jury on all degrees of homicide which the evidence tended to prove, even when such instructions were not requested.
See, e.g., Walton v. State,
D. INEFFECTIVE ASSISTANCE OF COUNSEL
Ineffective assistance of counsel claims are mixed questions of law and fact.
See, e.g., Williamson v. Ward,
*556 1. Dr. Garcia’s letter
Mr. James argues his trial counsel’s failure at the sentencing phase to present a letter from Dr. Garcia, which indicated Mr. James would not be a continuing threat to society, constituted ineffective assistance of counsel. Mr. James first raised this claim in a post-conviction proceeding, and the Oklahoma Court of Criminal Appeals determined it was procedurally barred.
See James,
As a matter of state law, “Oklahoma generally bars review in postconviction proceedings of ineffective assistance of trial counsel claims not raised on direct appeal.”
Hooks v. Ward,
Without elaboration, Mr. James urges us to remand to the district court to allow him to raise ineffective assistance of appellate counsel as cause excusing this default.
6
Even if this request were somehow sufficient to show cause, Mr. James has not shown prejudice by trial counsel’s failure to introduce the letter as evidence. Introduction of the letter would have permitted the State to call Dr. Garcia as a witness. Counsel did not want Dr. Garcia to testify at sentencing because he believed Dr. Garcia would have made a strong statement there was nothing wrong with Mr. James. This testimony would have conflicted with the thrust of Mr. James’ defense at both stages of the proceedings that his emotional problems, turbulent childhood, history of drug abuse, and voluntary intoxication on the night of the murder diminished his culpability. The failure to introduce the letter was thus sound, although unsuccessful, strategy. “To counteract the natural tendency to fault an unsuccessful defense, a court reviewing a claim of ineffective assistance must ‘indulge a strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance.’ ”
Nix v. Whiteside,
2. Failure to investigate and present mitigating evidence
Mr. James argues his counsel was ineffective during the sentencing phase for failing to investigate and present a proper case for mitigation.
7
The federal district court found this claim procedurally barred but also considered it on its merits and determined Mr. James failed to show coun
*557
sel’s strategy at the sentencing hearing was unreasonable. The State does not argue procedural bar, even though the Oklahoma Court of Criminal Appeals held the claim barred,
see James,
Mr. James faults his attorney for failing to call several of his relatives to testify about his turbulent childhood, his problems with drugs, and their love for him. Counsel has a duty to conduct a reasonable investigation for mitigating evidence or to make a reasonable decision that particular investigation is unnecessary.
See, e.g., Stouffer v. Reynolds,
At the post-conviction hearings, counsel testified, contrary to Mr. James’ assertion, that he talked to Mr. James about his family and his background. Although he spoke to Mr. James’ father and grandparents on several occasions, he did not ask them to testify. Counsel testified that the father was antagonistic toward Mr. James and would not have made a sympathetic witness. He also testified that the grandfather was old and in poor health, and that Mr. James requested he not be called as a witness. Counsel could not recall his reasons for not calling the grandmother. He did ask Mr. James if there were other people who could testify in mitigation. Mr. James gave him no names, however, and counsel left it up to Mr. James to decide what family members to call. Based upon our independent review of the state court record,
see Smallwood,
Even if counsel’s performance was deficient in this regard, Mr. James has not shown prejudice. Much of the evidence he now points to was already before the jury. At the guilt stage, he testified regarding his problems with drugs. At the punishment stage, he testified about his disruptive home life, his drug problem since the age of twelve, his hospitalization for the drug problem, his lack of prior felony convictions, his remorse, and his young son. Given the aggravating evidence, there is no reasonable probability the additional and largely cumulative mitigating evidence would have caused the jury to reach a different result.
See Castro,
E. SUFFICIENCY OF THE EVIDENCE TO SUPPORT AGGRAVATING CIRCUMSTANCES
1. “Serving a sentence” aggravator
Mr. James contends there is insufficient evidence to support the aggravating circumstance that “[t]he murder was committed by a person while serving a sentence of imprisonment on conviction of a felony.” Okla. Stat. tit. 21, § 701.12(6). At the time of the murder, Mr. James had pled guilty to a federal felony but had not been sentenced. He thus maintains he was not “serving a sentence” as required by the statute.
*558
The federal district court assumed the issue was not procedurally barred and determined that a rational trier of fact could have found the existence of this aggravator beyond a reasonable doubt. Citing-Black’s Law Dictionary 301 (5th ed.1979) and
Boykin v. Alabama,
The State argues this claim is procedurally barred because it was first raised on post-conviction review and the Oklahoma Court of Criminal Appeals found it could have been raised on direct appeal.
See James,
Although we are uncertain of- its exact review, the Oklahoma Court of Criminal Appeals on both direct appeal and on post-conviction review considered only very generally whether the evidence supported the aggravating factors. The issues presented on mandatory sentence review and on reweighing are in a different legal posture than a claim of insufficient evidence to support an aggravator. Although mandatory sentence review applies in all capital cases,
see
Okla. Stat. tit. 21, § 701.13(C), it does not take into consideration every possible attack on the aggravating circumstances.
Cf. Medlock v. Ward,
“On habeas review, this court does not address issues that have been defaulted in state court on an independent and adequate state procedural ground, unless the petitioner can demonstrate cause and prejudice or a fundamental miscarriage of justice.”
English,
In any event, we are not persuaded the claim has merit. In contending there is insufficient evidence to support this aggravator, Mr. James faults the state court for broadening the aggravator beyond the words of the statute to include a murder committed by a prisoner after pleading guilty and while awaiting sentencing. Our review of a challenge to the state’s interpretation of an aggravating factor is quite limited. “As the Supreme Court has made clear, unless the aggravator is unconstitutionally vague on its face, or otherwise impedes the requirement that sentencing determinations be individualized, states are free to select whatever substantive criteria they wish to determine who is eligible for the death penalty.”
Davis v. Executive Director of Department of Corrections,
This is not a case where the state court’s interpretation of the aggravator is over-broad.
See Cartwright v. Maynard,
The evidence here was uncontroverted that at the time of the murder Mr. James was incarcerated after pleading guilty to a felony. Under the Oklahoma court’s interpretation, therefore, a rational factfinder could have found this aggravator beyond a reasonable doubt.
See Jackson v. Virginia,
2. Continuing threat aggravator
The existence of the “continuing threat” aggravator was supported by evidence that Mr. James had a homemade weapon in prison, showed a lack of remorse over the killing, and threatened other inmates. The jury was also instructed to consider the callousness of the crime and Mr. James’ criminal history. Mr. James contends this evidence is not sufficient to demonstrate a propensity toward future violent conduct. He points out that he was originally incarcerated for a nonviolent offense and has perpetrated no further violent acts while in prison. We review this claim under the “rational factfinder” standard. See id.
A defendant’s criminal history, the callousness of the crime, and his threats against others are among the factors which may be considered in determining if there was sufficient evidence to support the continuing threat aggravator.
See Medlock,
Contrary to Mr. James’ contention, a pattern of criminal activity is not required to prove this aggravator.
See Malone v. State,
*560 III.
We have considered all of Mr. James’ arguments on appeal, including those not specifically addressed, and are not persuaded constitutional error infected his trial. We AFFIRM the district court’s denial of habeas corpus relief.
Notes
. Mr. Brown pleaded guilty to second degree murder and testified for the state.
. The jury also found Mr. Van Woudenberg guilty of first degree murder and fixed his sentence at death.
. Although the trial court held a competency hearing, its competency determination is not entitled to a presumption of correctness because it used an unconstitutional standard of proof; it is as if no competency hearing was held at all.
See Wallace v. Ward,
. Because the Supreme Court decided
Ake
while Mr. James' case was pending on appeal, application of
Alee
presents no retroactivity problem.
See Johnson v. Gibson,
. There was some evidence that Mr. James had suffered from such a syndrome in 1974, but doctors found no evidence that he continued to suffer from it at the time of the murder.
. Mr. James also argues this claim cannot be procedurally barred because the State did not cross-appeal from the district court's ruling that it could consider the claim on its merits. We recently rejected this argument in
Jones v. Gibson,
. Mr. James also argues his attorney was ineffective for making a very brief opening argument at the sentencing phase. In light of the scant mitigating evidence presented, this short opening statement may have been a tactical decision. Indeed, our cases establish that failure to make
any
opening statement at this stage may be a tactical decision.
See Nguyen,
. Mr. James also asserts the continuing threat aggravator is unconstitutional on its face and as applied. We have repeatedly rejected this argument,
see, e.g., Hooks,
