Opinion

PER CURIAM: *

Petitioner-Appellee Walter J. Koon petitioned the district court for writ of habeas corpus, asserting that his trial counsel, Kevin Monahan, violated his constitutional right to effective assistance of counsel during both the guilt/innocence and penalty phases of his murder trial in state court. The district court granted Koon’s petition, reversing and vacating his conviction on three counts of first degree murder (and thus his death sentence) and remanding to state court for a new trial. Respondent-Appellant Warden Burl Cain, on behalf of the State of Louisiana, appeals the district court’s grant of habeas relief, insisting that the court erred in (1) failing to afford proper deference to the state court’s decisions and rulings; (2) concluding that Koon was denied effective assistance of counsel during the guilt/innocence phase of his trial; (3) concluding that Koon was denied effective assistance of counsel during the penalty phase of his trial; and (4) denying the State’s motion for a new trial. 1 We find no merit to the State’s contention that the district court failed to afford proper deference to the state court’s decisions and rulings. And, convinced that the district court applied the proper legal standards to the relevant facts and reached the correct conclusions, we affirm its grant of Koon’s petition on the basis that he was denied effective assistance of counsel dur *383 ing the guilt/innocence phase of his trial. 2 Finally, we conclude that the district court acted within its discretion when it denied the State’s motion for a new trial.

I. FACTS AND PROCEEDINGS

Around noon on March 5, 1993, Koon, along with his passenger, Sarah Robinson, drove to the Baton Rouge home of his in-laws, where his estranged wife, Michelle Guidry, was staying. After parking his truck in the driveway of the Guidry residence, Koon walked to the backyard, where he shot and killed his wife before entering the home and shooting and killing her parents. After observing Koon shoot his wife, Robinson ran screaming from Koon’s truck into the Guidry residence, where she hid until Koon had left the scene. Immediately following the shootings, Koon drove to his home in Livingston Parish, where he called the local authorities and turned himself in for the killings.

Koon was charged with three counts of first degree murder. He was initially represented by the Office of the Public Defender; however, after voicing his dissatisfaction with this representation, the Louisiana state court appointed Monahan, a private criminal defense attorney, to represent Koon jointly with the public defender. Soon thereafter, a private attorney, Denise Vinet, was substituted for the public defender as co-counsel. At the beginning of Koon’s trial in March 1995, though, Monahan informed the court that Vinet wished to withdraw, stating that Vi-net’s assistance was not needed. Vinet also indicated that her withdrawal should not be a problem because Monahan had not asked her to do a thing on the case. The court granted Vinet’s motion to withdraw, but only after Koon waived any objection. No assistant counsel was appointed to replace Vinet.

At trial, Monahan entered Koon’s dual plea of not guilty and not guilty by reason of insanity. Monahan’s defensive strategy centered on Koon’s mental state at the time of the killings. Specifically, Monahan elected to emphasize that Koon “just had one bad week” in an effort to negate his specific intent and lessen his culpability for his actions. Monahan would introduce evidence that, by the end of the week, Koon’s wife had left him; he had become ill; he had a tax lien levied against him; and he had just learned that his wife was having an affair (which, according to Koon, had been disclosed to him by Robinson while they were riding in Koon’s truck en route to the Guidry residence). In addition, Monahan had been told by Koon that he was not using drugs, Xanax, or alcohol when he shot and killed the Guidrys but that he had been doing so in the early morning hours that day as well as in the preceding weeks, leading Monahan to theorize that Koon was suffering from “withdrawal” effects at the time of the killings. According to Monahan, these detoxification effects combined with Koon’s “bad week” to render him unable to tell right from wrong when he shot his estranged wife and her parents.

Monahan enlisted the help of a few medical experts to assist in his presentation of this insanity/manslaughter defense. His chief expert, Dr. Marc Zimmerman, who *384 testified that Koon’s detoxification contributed to his inability to tell right from wrong at the time of the killings, was hired by Monahan the day before Koon’s trial began and had only an hour to interview Koon before testifying. Zimmerman’s testimony was torn apart by the State’s opposing expert, Dr. Donald Hoppe, who criticized Zimmerman’s cursory interview of Koon as well as Zimmerman’s failure to interview Koon’s family members and close friends. Furthermore, Hoppe, a clinical psychologist who had not interviewed Koon but had reviewed the results of the MMPI test conducted by Zimmerman, ventured that Koon’s test results showed that he was not remorseful; was a liar; was manipulative; and was violent. Mona-han was unprepared — and, in fact, made no attempt — to counter the State’s devastating rebuttal, even though it turned out that there was little in the literature to support Hoppe’s broad interpretation of Koon’s test results.

Koon’s insanity/manslaughter defense was dealt another blow when Robinson, the lone eyewitness to the killings, whom Monahan had failed to interview prior to trial, contradicted Koon’s own testimony by denying that she had told him shortly before the killings that his wife was having an affair with one Joey Leblanc, a person Koon particularly disliked because he had been betrayed by Leblanc in the past. Robinson also contradicted Koon’s testimony that he had consumed alcohol and drugs (including Xanax) the morning of the killings.

The jury convicted Koon of first degree murder on all counts and sentenced him to death. Koon appealed his conviction and sentence to the Louisiana Supreme Court on 11 different grounds, but that court affirmed. 3 Koon then moved for post-conviction relief in state court based on ineffective assistance of counsel. In anticipation of his post-conviction relief hearing, Koon requested that the court issue subpoenas directing the attendance of 33 witnesses at the hearing; however, the court limited him to two: Monahan and Vinet. Following Monahan’s and Vinet’s testimony, the state court denied Koon relief, concluding that Monahan “did a good job with what he had to work with.”

After Koon exhausted his available state court remedies, he filed this petition for writ of habeas corpus in the United States District Court for the Middle District of Louisiana. The district court first granted Koon an opportunity to present the evidence that the state court had disallowed in its post-conviction relief proceeding. After holding a hearing and considering evidence concerning Monahan’s performance during both the guilt/innocence and penalty phases of Koon’s trial, the district court granted Koon’s petition, vacating his conviction and sentence and remanding to state court for a new trial.
