Keith Leon Wallace appeals from the judgment entered on a jury verdict finding him guilty of possessing a sawed-off shotgun in violation of 26 U.S.C. §§ 5861(d) and 5871 (1970) and 18 U.S.C. § 2 (1970). He asserts that his conviction was improper because (a) the indictment should have been dismissed since it was based on hearsay evidence when competent evidence was readily available, (b) the district court declined to turn over transcripts of the grand jury proceedings for use at trial, and (c) the district court's charge incorrectly instructed the jury on the doctrine of constructive possession. Wallace also argues that the district court improperly denied his motion for new trial supported by the affidavit of an essential government witness, stating that he had testified falsely at the trial.

We see no merit in defendant's direct attacks on the validity of his conviction, but we remand the case to the district court for further consideration of the motion for a new trial.

Disposition of Wallace's first three assignments of error need not detain us long. First, we see no merit in Wallace's contention that the indictment against him was invalid because it was obtained through the use of hearsay testimony. Costello v. United States, 350 U.S. 359, 76 S. Ct. 406, 100 L. Ed. 397 (1956), held that an indictment may be based on hearsay evidence.

Equally lacking in merit is Wallace's contention that the trial court erred in not requiring the United States Attorney to turn over minutes of the grand jury proceedings against his client. In United States v. Chase, 372 F.2d 453 (4 Cir.), cert. denied, 387 U.S. 907, 913, 87 S. Ct. 1688, 1701,18 L.Ed.2d 626, 635 (1967), we decided that a defendant must show a particularized need in order to justify access to the records of grand jury proceedings. No such showing was made in the instant case.

Wallace's third assignment arises from the district judge's inclusion of the term 'constructive possession' in the charge to the jury.1 We disagree that the use of the phrase, without definition, caused the instruction to be self-contradictory and permitted the jury to speculate about its meaning. The only testimony at trial regarding possession indicated that the shotgun was in the back seat of defendant's car which the defendant was driving. It is more likely that, if possession were to be found, it would be actual possession rather than constructive possession. In any event, there was no objection to the charge and we hold that the failure to define constructive possession under these circumstances was not plain error.

We turn to the correctness of the district court's ruling on Wallace's motion for a new trial on the basis of the post-trial recantation of the essential government witness. The witness was defendant's brother, George Edgar Wallace, Jr. At trial, the brother, exhibiting great emotional stress, testified that the defendant had indicated to him knowledge of the gun in the back of the car. After trial, however, the witness made an affidavit that his original testimony had been false.2

The district court denied the motion for a new trial. It asserted that at a post-trial hearing grounded upon a recantation of testimony, the court is not to consider which version of the witness's story is true, but rather only to ensure that there has been no prosecutorial misconduct by way of intimidation or threats to testify falsely. Since the district court found that the witness had neither been intimidated or threatened, nor coached or invited to testify falsely, denial of the motion followed.

The district court in this case misconceived the proper scope of the inquiry it should have made. The applicable standards for the granting of a new trial based upon a witness's recantation were set out in Larrison v. United States, 24 F.2d 82, 87--88 (7 Cir. 1928). There, the court stated that a new trial should be granted when:

(a) The court is reasonably well satisfied that the testimony given by a material witness is false.

(b) That without it the jury might have reached a different conclusion (emphasis in original).

(c) That the party seeking the new trial was taken by surprise when the false testimony was given and was unable to meet it or did not know of its falsity until after the trial.

Accord, Newman v. United States, 238 F.2d 861, 862 n.4 (5 Cir. 1956); Gordon v. United States, 178 F.2d 896, 900 (6 Cir. 1949), cert. denied, 339 U.S. 935, 70 S. Ct. 664, 94 L. Ed. 1353 (1950); 2 Wright Federal Practice and Procedure § 557 at 525 (1969).3

These standards delineate the scope of the district court's proper inquiry. In this case, the district court failed to make even the first of the three necessary determinations. We therefore remand the case for a new determination of Wallace's motion for a new trial in the light of the Larrison case's standards.

We reject Wallace's contention that we should order a new trial based on the recantation. At best, it is difficult for an appellate court to assess the veracity of witnesses by reference to a bare record. The district judge is in a far better position to determine which version of the testimony of George Edgar Wallace, Jr., is more likely the truth, having observed the demeanor of the witness both at trial and at the post-trial hearing. See United States v. Johnson, 327 U.S. 106, 66 S. Ct. 464, 90 L. Ed. 562 (1946); United States v. Johnson, 487 F.2d 1278 (4 Cir. 1973). Of course, from this record we can say that if it is determined that George Edgar Wallace, Jr., told an untruth at trial, the jury unquestionably might have found defendant not guilty if his brother's testimony were not in the case. We express no view, however, as to whether defendant was surprised by his brother's testimony or learned of its falsity only after trial.

Vacated and remanded.
