check and splitting the proceeds with Pack is such cogent evidence of guilty knowledge and intent as to be clearly admissible.
When the Texas check is considered together with the other evidence of guilty knowledge, there is no doubt of its sufficiency to justify the belief that King knew the check which Pack was going to cash at the store was forged. And • King’s driving Pack to the store and participating in the proceeds justified the belief beyond a reasonable doubt that he was a conscious participator in the criminal venture and had wilfully acted to make it succeed. See United States v. Garguilo, supra; United States v. Klein, 2 Cir., 340 F.2d 547; Long v. United States, 124 U.S.App.D.C. 14, 360 F.2d 829; United States v. Ragland, 2 Cir., 375 F.2d 471. Our case is clearly distinguishable from Hendrix v. United States, 5 Cir., 327 F.2d 971, where the lady defendant was a mere passenger along with three other persons and did not share in the proceeds.
King also complains of the trial court’s refusal to grant his motion for a bill of particulars to set forth what act or acts constituted aiding and abetting and his motion for a new trial on the basis of newly discovered evidence.
We are acutely and sympathetically aware that Rule 7(f), F.R.Cr.P., has been amended for the purpose of liberalizing the office of the bill of particulars. See Notes of Advisory Committee on Rules, Rule 7(f), F.R.Cr. P., appendix at 81. The liberalization was undoubtedly in recognition of the trend toward fuller disclosure of the Government’s case to better serve the ends of criminal justice. While the discretion continues to reside in the trial court, it should be freely exercised with an awareness that an indictment may be sufficient on its face to state an offense, yet insufficient to adequately inform the accused of the charge against him to enable him to properly prepare his defense and, at least, to avoid prejudicial surprise. See Will v. United States, 389 U.S. 90, 88 S.Ct. 269, 19 L.Ed.2d 305; United States v. Smith, D.C., 16 F.R.D. 372. See also Wong Tai v. United States, 273 U.S. 77, 47 S.Ct. 300, 71 L.Ed. 545; Cefalu v. United States, 10 Cir., 234 F. 2d 522; Meer v. United States, 10 Cir., 235 F.2d 65.
While it is no answer to a denial of a bill of particulars to say that a defendant knew what he did, it is generally sufficient we think if the defendant is informed of what the Government will claim he did. King did in fact know all along that the Government would claim that he drove Pack to the store and later split the proceeds because King admitted these facts to an FBI agent whose report was made available under Rule 16, F.R.Cr.P. No prejudicial surprise resulted and the defendant’s right to a fair trial was not infringed.
Before a new trial for newly discovered evidence should be granted, the defendant has the burden to show that the evidence was discovered since trial, facts from which the court may infer reasonable diligence on the part of the movant, and that the evidence is not merely cumulative or impeaching but is material and of such character that on a new trial such evidence would probably produce a different result. The granting of the motion rests in the sound discretion of the trial judge and the denial will not be reversed in the absence of plain abuse of discretion. See Robinson v. United States, 10 Cir., 345 F.2d 1007; Casias v. United States, 10 Cir., 350 F.2d 317; Wion v. United States, 10 Cir., 337 F.2d 230; Baca v. United States, 10 Cir., 312 F.2d 510; Long v. United States, 10 Cir., 139 F.2d 652.
The newly discovered evidence in affidavit form relied upon for the new trial was to the effect that the two affiants were present in an auto store where Pack was writing on something which turned out to be the check in question, that there were several people gathered around a counter arrangement while Pack was writing, and that King was standing eight or ten feet away at
