Dickson, a convicted murderer, appeals the judgment of the district court denying his writ of habeas corpus. Dickson argues (1) that the trial judge’s finding that the jury’s exposure to extraneous information was limited to a single statement by a deputy sheriff is clearly erroneous, and (2) that the State of Oregon failed to prove that receipt by state jurors of extrinsic evidence was harmless beyond a reasonable doubt. We have jurisdiction pursuant to 28 U.S.C. § 2253. Because our review of the record convinces us that there is a reasonable possibility that the extrajudicial statement influenced the state court verdict, we reverse the judgment. Consequently, it is unnecessary for us to consider whether the trial judge erred in failing to find that other misconduct occurred.
I
On November 7, 1981, Anderson, owner of the Alibi Tavern in Grants Pass, Oregon, was murdered and robbed while working at the saloon. A police examination and autopsy revealed that repeated blows from a pool cue and other objects caused Anderson’s death. There were no eyewitnesses to the murder. The state based its case linking Dickson to the murder principally on testimony that Dickson was at the saloon both before and after the murder, on footprints matching Dickson’s shoes found in the blood on the saloon floor, and on the testimony of a fellow inmate who stated that Dickson had admitted while in jail that he killed Anderson. The state also introduced evidence that Dickson had in his possession money approximating the amount that was taken from the saloon on the night of the murder and that Dickson’s fingerprints were found on various items at the scene.
Dickson responded to this evidence by testifying that he had been in the tavern before the murder and that he returned later in the evening to find Anderson dead. He admitted checking the cash register for money but testified that the cash register was empty. He also admitted that he took the victim’s car keys and stole his car. As for the money he possessed, Dickson testified that a woman with whom he spent an evening had given him approximately $100 and that he had stolen an additional $200 from her. Other evidence introduced at trial established that Dickson had previously been convicted for credit card fraud and was on temporary leave from an Oregon state prison.
*405 After one and a half days of deliberations, the jury returned a unanimous verdict of guilty. Two days after the jury verdict, Dickson’s lawyer reported to the trial court that one of the jurors had received a newspaper clipping during trial regarding an alleged past conviction of Dickson. The trial court found that an evidentiary hearing was warranted to determine whether any of the jurors had considered extraneous information in reaching the verdict. After questioning several jurors under oath over a period of four days, the trial judge found that the allegation concerning the newspaper clipping was unsubstantiated. However, he found that a deputy sheriff responsible for escorting the jurors to and from the courtroom had made a statement to two jurors to the effect that Dickson had “done something like this before.” He further found that the statement was made between two and six days before the jury retired for deliberations and that neither of the jurors had discussed the statement among themselves or with other members of the jury. He also found that the two jurors had followed his jury instructions limiting the use of prior convictions and directing them to make their decision exclusively on the trial evidence. The trial judge concluded that the remark had not influenced the jury’s deliberations, and denied Dickson’s motion for a new trial.
On appeal, the Oregon Court of Appeals found that the deputy sheriff’s comment violated Dickson’s sixth amendment right to confrontation, but held that the error did not warrant reversal of Dickson’s conviction.
State v. Dickson,
II
We review the district court’s denial of Dickson’s habeas corpus petition de novo.
Bayramoglu v. Estelle,
A defendant is entitled to a new trial when the jury obtains or uses evidence that has not been introduced during trial if there is “a reasonable possibility that the extrinsic material
could
have affected the verdict.”
Id.
(emphasis in original),
quoting United States v. Vasquez,
Dickson claims here, as he did in his state appeal, that a reasonable possibility exists that the deputy sheriffs statement to two of the jurors affected the verdict. When a jury is exposed to facts that have not been introduced into evidence, a defendant has effectively lost the rights of confrontation, cross-examination, and the assistance of counsel with regard to the extraneous information.
Marino,
The trial court concluded that the jurors followed instructions directing the jury to base its decision solely on evidence admitted at trial. However, the question whether the introduction of the extrinsic evidence in this case was prejudicial is not a question of historical fact entitled to deference on appeal, but a mixed question of law and fact reviewed de novo.
Marino,
We have previously identified several factors relevant to determining whether the prosecution has successfully rebutted the presumption of prejudice arising from the introduction of extraneous evidence. These are:
(1) whether the material was actually received, and if so, how; (2) the length of time it was available to the jury; (3) the extent to which the juror discussed and considered it; (4) whether the material was introduced before a verdict was reached, and if so at what point in the deliberations; and (5) any other matters which may bear on the issue of the reasonable possibility of whether the extrinsic material affected the verdict.
Marino,
Subsequent cases have similarly stressed the nature of the extraneous information
*407
when determining whether there existed a possibility that the information affected the verdict.
Compare Littlefield, 752
F.2d at 1432 (new trial required where magazine article describing fraudulent tax scheme as a problem of national concern and deploring light sentences imposed on participants brought into jury room during trial for tax fraud),
and Gibson,
In the case before us, the trial court found that the jury had not discussed the deputy’s statement during their deliberations. However, it is clear that the deputy s comment was both directly related to a material issue in the case and highly inflammatory. There is a direct and rational connection between the statement that Dickson had “done something like this before” and the conclusion that Dickson had done “this” again.
See United States v. Lewis,
The state argues that given other evidence introduced at trial relating to defendant’s past, the deputy’s statement that Dickson “had done something like this before” is merely cumulative of other infor *408 mation properly in evidence, and thus not prejudicial. However, there was no evidence introduced at trial that Dickson had previously engaged in any acts of violence, let alone an act as brutal and serious as the one with which he was charged. The only evidence of Dickson’s other “bad acts” on the record were a conviction for credit card fraud, evidence that Dickson had served time in a state prison, and Dickson’s admissions that he stole the deceased’s car and took money from a woman with whom he had spent an evening. Though these “bad acts” may have indicated to the jury that Dickson had an unsavory character and a propensity to steal, they in no way suggest that Dickson was a brutal and dangerous man. The deputy’s comment, in contrast, suggested for the first time that Dickson was not a stranger to violence. Dickson was on trial for bludgeoning a man to death with a pool cue. The deputy’s comment that Dickson had done “something like this before” can only be understood as referring to a previous act of brutality or murder.
We cannot, therefore, accept the state’s argument that the deputy’s comment was merely cumulative of other evidence on the record. To do so would contradict our cases recognizing that evidence of prior criminal acts is highly prejudicial.
See, e.g., Lewis, 787
F.2d at 1323;
Bagley,
Nor can we accept the state’s argument that the trial court’s instructions to the jury eliminated any remaining doubt that the comment did not influence the two jurors who heard it. Although we ordinarily assume that instructing the jury to disregard extraneous evidence sufficiently ensures that inadmissible evidence will not influence the jury,
see Bagnariol,
To tell a jury to ignore the defendant’s prior convictions in determining whether he or she committed the offense being tried is to ask human beings to act with a measure of dispassion and exactitude well beyond mortal capacities.
Lewis, 787
F.2d at 1323,
quoting United States v. Daniels,
Finally, we cannot accept the state’s contention that the fact that the prejudicial information was communicated to only two jurors is relevant to our harmless error analysis in this case. Dickson was entitled to a unanimous verdict. If only one juror was unduly biased or improperly influenced, Dickson was deprived of his sixth amendment right to an impartial panel.
United States v. Hendrix,
Ill
Our analysis of the likelihood of prejudice in this case leads us to conclude that a reasonable possibility exists that the two jurors who were present when the remark was made were influenced in their determination of Dickson’s guilt. This conclusion is consistent with, if not compelled by, our holding in
Vasquez,
where we found that the
possibility
that at least one juror had been exposed to extraneous information regarding a defendant’s past convictions warranted a new trial.
*409 We hold, therefore, that Dickson is entitled to a new trial. Since we find that reversal is required on the facts as found by the state trial court, it is unnecessary for us to reach the other error claimed by Dickson.
We reverse and remand to the district court to grant the petitioner’s writ of habe-as corpus unless the State of Oregon elects to grant a new trial within sixty days.
REVERSED.
