William Ferguson and Norman Wilson, veteran postal employees, appeal from the judgments entered on their convictions of destroying (eating) the сontents of two items of mail in violation of 18 U.S.C. §§ 1703(b) & 2. Their case was tried to a jury. With the parties’ consent, given pursuant to 28 U.S.C. § 636(a)(3) and 18 U.S.C. § 3401(a) & (b), the presiding judicial officеr was a United States Magistrate. Their convictions were affirmed by the district court, and we affirm both judgments.
I.
Defendants worked in the rewrap section of the mаin post office in Baltimore. Ferguson rewrapped or repaired parcels and Wilson repaired letters damaged in the course of handling by the post office. Ferguson was not authorized to open parcels any further than the condition in which *1019 they were found or to inspect or remove the contents of parcels.
The government’s evidence, primarily a video tape and surveillance by postal inspectors, showed thаt Ferguson removed a tin of cookies from a damaged parcel, opened the tin, ate several cookies, and handed one aсross the work table to Wilson. Ferguson also placed another damaged parcel containing candy bars, a “test” mailing, on the work table. He did nоt repair it and he invited Wilson to have a candy bar. Wilson took one, ate it, and threw away the wrapper.
Both defendants were immediately aрprehended and interrogated. In the course of interrogation Wilson gave a written incriminating statement.
II.
Before us, Ferguson and Wilson contend that: (1) the magistrate erred in denying their motions for severance under Rule 14 of the Federal Rules of Criminal Procedure; (2) the magistrate erred in refusing to give the jury a seрarate instruction requiring them to find beyond a reasonable doubt that the test parcel was “mail” within the meaning of 18 U.S.C. § 1703(b) in order to convict defendants; (3) the gоvernment’s closing argument and the magistrate’s jury instruction on the topic of aiding and abetting were prejudicial to Ferguson; (4) the magistrate improperly rеfused to give Wilson’s requested jury instruction regarding the effect of government agents’ promises or threats on the voluntariness of his confession; (5) certain оf the magistrate’s evidentiary rulings were erroneous; and (6) the statutes permitting defendants in misdemeanor eases to be tried and sentenced by a magistrate violate Article III of the Constitution.
III.
Because it raises an issue not heretofore addressed by us, we consider the last of defendants’ contentions first. While we, along with the great majority of the other courts of appeals,
see Gairola v. Virginia Department of General Services,
IV.
Defendants’ other contentions require little discussion. Their motions for severance were based on the theory that their defenses were irreconcilable. The motions were madе following closing arguments and were therefore untimely under
*1020
FecLR.Crim.P. 12(b)(5) & 12(f), which require that a motion for severance be made prior to trial or be deemed wаived. Each defendant had made a pretrial motion for severance based on the theory that admission of his codefendant’s out-of-court confession would be prejudicial,
see Bruton v. United States,
Defendants’ contention that a separate jury instruction requiring the jury to find beyond a reasоnable doubt that the “test parcel” was “mail” is without merit. The magistrate did instruct the jury that one of the three essential elements of the offense chargеd was proof beyond a reasonable doubt “that the defendant destroyed mail which was not directed to him.” (emphasis added). The jury was also told that a test or decoy parcel could be considered mail within the meaning of the statute, and the uncontradicted evidence was that this test parcel had been introduced into the regular stream of mail. The substance of the instruction requested and refused was encompassed within the instructions actually given. We therefore find no error in the magistrate’s ruling.
Similarly, we find no merit in Wilson’s contention that he was entitled to a jury instruction that specifically required the jury tо consider the effects of alleged threats of harm or promises of reward made by government agents on the voluntariness of his confession. He withdrew his objection to introduction of the confession, and thus he may not complain about its admissibility on appeal.
We also see no merit in Wilson’s contention that he was prejudiced by the magistrate’s refusal to allow him to testify on direct examination as to the circumstances surrounding his confession. Aftеr the government used Wilson’s confession in cross-examining him, Wilson was allowed to explain the circumstances of the confession on redirect exаmination. The magistrate’s ruling was a permissible exercise of his discretionary control over the “mode and order of interrogating witnesses and presenting evidence,” Fed.R.Evid. 611(a), and in no way prejudiced Wilson.
Ferguson’s contention that he was prejudiced by the government’s closing argument on aiding and abetting and the magistrate’s jury instruction with respect thereto, because both lacked an evidentiary predicate, is without merit. We agree with the district court that argument by government counsel suggesting a duty on Ferguson’s part to prevent damage to mail under his control was properly made in rebuttal to closing argument by defense counsel. We perceive no prejudicial error in the magistrate’s jury instruction in aiding and abetting. The instruction was standard and unexceptionable.
We perceive neither merit in defendants’ remaining assignments of error nor any need to discuss them.
AFFIRMED.
