On November 17, 1981, a sixteen-count indictment was filed which charged eight different individuals with various narcotics offenses. Eleven of the sixteen counts were applicable to defendants Manuel and Meynardo Montemayor. Seven of the eleven counts charged substantive offenses. The remaining four counts charged defendants with conspiracy offenses. Count 3 charged defendants with conspiracy to distribute cocaine; Count 4, with conspiracy to distribute heroin; Count 5, with conspiracy to distribute marihuana. Each of these offenses was in violation of 21 U.S.C. §§ 841(a)(1) and 846. Count 9 charged defendants with conspiracy to manufacture and distribute heroin, knowing it would be imported into the United States, in violation of 21 U.S.C. §§ 959 and 963.
On January 26, 1982, a jury trial commenced with three of the eight named defendants on trial. 1 On January 28, at the close of the evidence, the district court dismissed the substantive counts. On February 1, the jury returned a verdict of guilty on each of the four conspiracy counts. After a poll of the jury revealed that one juror did not agree with the guilty verdict against co-defendant Alifonso Arredondo, the court granted a mistrial as to Arredondo.
Defendants Manuel and Meynardo Montemayor appeal their conviction on the four conspiracy counts. They claim that (1) the evidence was insufficient to convict them on any of the four counts, (2) the district court erred in admitting coconspirator hearsay statements, (3) the district court erred in denying defendants’ motion to dismiss the indictment for vagueness and motions for a bill of particulars and for disclosure of the grand jury transcript, (4) the district court abused its discretion in admitting scientific evidence showing cocaine residue on items used by the conspirators, and (5) the district court erred in polling the jury separately as to each of the three *112 defendants to determine if the guilty verdicts returned were unanimous. We find no merit in defendants’ last four contentions and we find the evidence sufficient to sustain the conviction for conspiracy to distribute cocaine. We therefore affirm the conviction on Count 3 for conspiracy to distribute cocaine and vacate the convictions on the other three conspiracy counts.
1. Facts
Construed most favorably to the prosecution, the record reflects support for the following version of events. In 1975, Benito Montemayor’s stepson, Ricky Lee Bowman, 2 who was on leave from the military, helped his stepfather and Salvador Flores count large sums of money and weigh and package marihuana in Benito’s trailer in Chicago, Illinois. Both Bowman and Flores went to Mississippi to have boxes welded underneath a 1972 Dodge van in order to transport the marihuana. Benito returned to Chicago by plane and Flores took the van to Texas. Flores brought the van back to Chicago loaded with marihuana which Bowman helped him unload and take into Benito’s house. After Bowman’s undesirable discharge from the Army in March 1976, Bowman, along with his mother Eva, and Flores, assisted Benito in packaging marihuana and cocaine and in counting large sums of money — roughly amounts of $20,-000 to $30,000 per person — three or four times a'week. 3 Bowman testified that in 1976 he helped Benito package marihuana about fifteen to twenty times and helped package cocaine about five to seven times; he testified that pursuant to Benito’s instructions he helped unload cocaine and marihuana from the Dodge van in Chicago on fifteen to twenty occasions. Bowman also testified that the cocaine and marihuana came from somewhere in Mexico and that Flores, who drove the van, told him that he, Flores, always crossed the border at Laredo.
Drug Enforcement Administration (DEA) Agent Frank Tucci, working in an undercover capacity, purchased one pound of heroin from Flores in March 1976 in Chicago. Agent Tucci later spoke over the phone to a man who identified himself only as Flores’ boss about both the purchase of the one pound of heroin and additional purchases of heroin. The boss told Agent Tucci that he “operated big” and could swing “six, seven, eight” as many as Tucci wanted, “in a day.” Agent Tucci later spoke to Benito in person at his trailer and recognized his voice as the voice of the person who had identified himself on the phone as Flores’ boss.
Defendant Meynardo entered the picture in the summer of 1977 in Chicago where he took part in a conversation about heroin with his brothers Benito, Matías, and Reyes. At that time, Bowman heard Meynardo and Reyes agree with Matías to go to Detroit to “take care of the deal” — to pick up thirty-two kilos of heroin.
Around August or September 1977, Benito, along with his wife and children, moved to a house in Monterrey, Mexico. Bowman testified that in the fall of 1977 there were at least five meetings in a brothel in that city. Defendants Manuel and Meynardo were both present at all of those meetings along with three of their brothers — Benito, Matías, and Reyes — and Bowman. The topic of discussion at these meetings was multikilogram cocaine and heroin deals in Detroit. Bowman testified that there was a period when Matías, who was the lead brother, had to get the approval of all of his brothers before a cocaine deal could be approved, or, in their parlance, could “go down.” Bowman’s testimony was that all the brothers agreed that a particular cocaine deal was a “good deal” and that Meynardo, Manuel and the other brothers gave their approval to various transactions. Also during the fall of 1977, after the move to Monterrey, Bowman helped load and unload large amounts of money and drugs concealed behind the taillights and fender wells of a Chevrolet Blazer. Bowman testified that defendant Meynardo, along with Beni *113 to, Matías, Reyes, and a banker, was present on one occasion when Bowman helped count $500,000. Bowman was unable to recall whether Meynardo had helped count the money. The only time Bowman took the Blazer out it was loaded with cocaine and he took it to Huero Macias’ 4 house in Cerralvo, Mexico.
On another occasion in the fall of 1977, Bowman went to Meynardo’s house in Laredo where Bowman heard Benito and Meynardo talking about a load of marihuana that had not arrived. Meynardo protested to Benito that “it wasn’t his fault.”
Another event in the fall of 1977 was a birthday celebration for Matías near Cerralvo. 5 Among the guests were defendants Manuel and Meynardo, Bowman, Reyes, Matías, Benito, Robie (a sixth brother), Matías’ bodyguards, workhands, a band, and some women from the brothel. Defendants Manuel and Meynardo, Bowman, Benito, Matías, Reyes, and Macias (the chemist) took a twenty-minute walk into the woods until they arrived at a cave which Benito called their “heroin lab.” Everyone, including defendants Manuel and Meynardo, went inside the cave where two workhands were using wooden paddles to stir heroin in two large vats over a fire. The hands were skimming a brown substance off the top of the heroin and throwing it in piles on the ground. After observing for ten to twenty minutes, everyone except the two work-hands went back to the ranch. When Bowman returned to Monterrey, he was instructed to clean the brown skim off both his own boots and Benito’s. What Bowman finally had to do was to burn Benito’s boots, which were badly corroded on the bottom, and all of their clothes.
Other heroin transactions took place in Chicago during this same period of time until about February 1978. These involved ten to eleven sales of pounds of heroin on credit by Reyes to Carlos Gutierrez, who at the time of trial was incarcerated in Chicago. On the occasion of one of these sales, Benito and Matías were also present and Reyes obtained Matías’ approval before selling Gutierrez an additional pound. On another occasion when they were “sniffing” cocaine, Reyes told Gutierrez that his (Reyes’) brothers were bringing cocaine to Chicago, although Reyes did not name the brothers.
In the fall of 1979, there were several drug-related meetings and get togethers in the guesthouse behind Benito’s house in McAllen, Texas. Defendants Manuel and Meynardo attended these meetings and parties which occurred during a three-week period when Bowman stayed at the guesthouse. Although Bowman did not actually see the weighing and packaging, he stated that defendants Manuel and Meynardo, along with Benito, Matías, and Pancho, weighed and packaged cocaine on the pool table at the parties. Pursuant to Benito’s instructions, Bowman cleaned the pool table with a brush after each such party. After one of the parties in the guesthouse, defendants Manuel and Meynardo, Benito and Matías, among others, were standing outside around the Chevrolet Blazer and a basket of cocaine. 6 Bowman refused to follow Benito’s instructions to take a screwdriver and help Pancho load the fender wells of the Blazer. As Bowman left to go back to the house, he observed Pancho prepare to take the fender wells off. When Bowman later returned, the Blazer and people were gone. Subsequent to this occasion, defendants Manuel and Meynardo were present at another gathering which involved loading the Blazer and which culminated in a “coke-snorting” party in the guesthouse. Still another meeting in McAllen took place in the master bedroom of Benito’s house rather than the guesthouse. Defendants Manu *114 el and Meynardo, as well as Matías and Pancho, entered Benito’s bedroom carrying duffle-type shoulder bags, locked the door, and emerged after two hours with the bags.
Finally, it was brought out at trial that Meynardo had amassed a wealth disproportionate to his legitimate employment: he had put $125,000 cash down payment on a house in Laredo; he ran a used car lot in (Nuevo) Laredo, Mexico; he was a part owner in a Mexican corporation; he also had a grocery store which was ultimately sold at a sheriff’s auction in Chicago.
II. Sufficiency of the Evidence
Defendants first contend that the evidence was insufficient to support a conviction on any of the four conspiracy counts. Both the Government and defendants agree that the concurrent sentence doctrine is applicable to this case. Under that doctrine, the existence of one valid conviction may make unnecessary the review of other convictions when concurrent sentences have been given.
United States v.
Rubin,
The jury found each of you Defendants guilty on these counts and I think that the evidence is wholesome and adequate to support that verdict if they accepted the government’s evidence as they obviously did. And I think that when you take into account all the evidence and not isolate it, but just take all the circumstances, I feel that the evidence is sufficient to support these various findings on these various counts.... I am satisfied that the way the matter was submitted to the jury, that the jury had factual evidence before it to make the findings it did beyond a reasonable doubt on each of the conspiracy counts as it was submitted because it was a multicount indictment.
And I am going to sentence you on Counts 3, 4 and 5 and 9, each of the Defendants, that they be placed in the custody of the Attorney General for a period of fifteen years. I am going to sentence a fine of $25,000.00, a fine of $25,000.00 against each of the Defendants. 8 The effect of this is that your sentence is on these counts.
[A]s I understand the law, that is my punishment and the effect of it is that the sentences will, in effect, be concurrent as matters now stand in my understanding of the law.
(emphasis added).
The judge further stated that if he thought there were multiple conspiracies he would assess a more severe sentence: “I feel there is just one conspiracy. If I did not feel that way, I would assess a more *115 severe sentence against you gentlemen.... If I am wrong in that, then you are very fortunate because if I — T would certainly consider some consecutive sentences in these cases had the law permitted it.” It is apparent that the judge consolidated the four counts because of a concern over the single versus multiple conspiracy doctrine and its implications for concurrent or consecutive sentencing. 9 Regardless of the correctness of the judge’s interpretation of the single/multiple conspiracy doctrine, his statements at the sentencing hearing leave no doubt that his intent was to impose concurrent sentences. 10
This Court will proceed to review the sufficiency of the evidence to support defendants’ conviction on Count 3, which charged a conspiracy to distribute cocaine. In conspiracy cases the Government must prove beyond a reasonable doubt that (1) a conspiracy to accomplish an unlawful purpose existed, (2) the defendant had knowledge of the unlawful conspiracy, and (3) the defendant voluntarily agreed to join the conspiracy.
United States v. Jackson,
The
en banc
Court in
United States v. Alvarez,
Applying these standards to the instant case we conclude that the evidence is sufficient to sustain a verdict of guilty for conspiracy to distribute cocaine. Concerning the second element of proof, knowledge of the unlawful conspiracy, the “aggregate of the evidence” is more than sufficient to establish that defendants “knew that criminal activity was afoot.”
11
See Alvarez,
Having affirmed the convictions on Count 3, the concurrent sentence doctrine is invoked to decline review of defendants’ convictions on the remaining three counts.
12
In
United States v. Rubin,
III. Other Allegations
A. Coconspirator Hearsay Statements
United States v. James,
The district court should, whenever reasonably practicable, require the showing of a conspiracy and of the connection of the defendant with it before admitting declarations of a coconspirator. If it determines that it is not reasonably practical to require the showing to be made before admitting the evidence, the court may admit the statement subject to being connected up.
Id. at 582. The district court did not err in allowing admission of Bowman’s hearsay statements subject to later connection. At the close of Bowman’s testimony, the court found that the James requirements were satisfied. The court’s James finding is not clearly erroneous.
B. Defendants’ Motion to Dismiss the Indictment, Motion for a Bill of Particulars, and Motion for Disclosure of Grand Jury Transcript
The indictment charged that the conspiracies ran from January 1,1970 to the filing of the indictment (Nov. 17, 1981). The evidence at trial implicated Meynardo and Manuel in the conspiracies from the summer of 1977 and the fall of 1977, respectively.
14
Defendants contend that the indictment was insufficient due to the vagueness or open-endedness of the time period alleged for the conspiracies charged in Counts 3, 4, 5, and 9. An indictment is sufficient if it (1) contains the elements of the offense charged and fairly informs a defendant of the charge against him and (2) enables him to plead an acquittal or conviction in bar of future prosecutions for the same offense.
Hamling v. United States,
In asserting error in the denial of defendants’ motion for a bill of particulars, defendants fail to allege surprise that prejudiced the preparation of their defense.
See United States
v.
Horton,
*118
Finally, defendants allege that the judge erred in denying their motion for disclosure of the grand jury transcript pursuant to
Dennis v. United States,
C. Admission of Scientific Evidence
A DEA chemist, Edwin Albers, testified regarding his analysis of cocaine residue removed from the pool table in McAllen and the compartments behind the taillights of the Chevrolet Blazer. First, defendants argue that this evidence should have been excluded because they were not given adequate warning that it would be introduced and therefore were taken by surprise. Defendants claims of surprise are not well-founded. Two weeks before trial the Government agreed to allow defendants access to the pool table to obtain their own samples for independent testing, as the sample of the material recovered by the DEA chemist had been entirely consumed in the course of chemical analysis to determine the presence of cocaine. Defendants failed to take advantage of this opportunity to conduct their own vacuum sweep on the pool table. In fact, ten days before trial began, defendants had contacted a chemist to be on call. Furthermore, the DEA-7 report (the chemist’s report) was available throughout discovery under the Government’s “open file” discovery provided in the case. Moreover, it is evident from defendants’ motion to suppress that they had in fact seen the chemist’s report by the first day of trial on January 26,1982. It is true that defendants did not receive a copy of the spectra from the mass spectrometer test (run on both the sample from the table and the Blazer) until after the DEA chemist testified. During the trial, however, the judge held Albers overnight in the event that defendants should desire that their own expert analyze the spectrograph reports. Defendants failed to do so. Nor did they request a continuance for this purpose.
See United States v. Bockius,
Second, defendants contend that Albers’ testimony should have been excluded because defendants were denied samples of the material recovered by the DEA chemist from the pool table and the Blazer in violation of Fed.R.Crim.P. 16(a)(1)(C). Albers testified that there was no substance whatsoever left following the two tests performed on the material from the pool table (gas chromatograph and mass spectrograph); the only materials remaining after the two tests on the sweepings from the Blazer were lint, dirt, and residue from which all the cocaine had been extracted. Thus, the samples which were vacuumed from the pool table and the Blazer were entirely consumed by testing. Defendants’ motion to suppress Albers’ testimony
15
based on the Government’s failure to pro
*119
vide a sample of the vacuumed material was therefore denied by the trial judge. The trial court concluded that since there was nothing the Government could provide, given that it had been necessary to use everything the Government had to conduct its own test,
16
the defendants could not be unfairly prejudiced on that account. This Court will not embark on a discussion of whether the substances were even discoverable under Fed.R.Crim.P. 16(a)(1)(C).
17
Assuming,
arguendo,
that the substances were discoverable, the issue would be whether the lack of the vacuumed material requires reversal because it would have been likely to change the verdict.
United States v. Gordon,
D. Repolling the Jury
Finally, defendants claim that the Court erred when it repolled the jury to determine if the guilty verdicts were unanimous as to each of the three defendants. The jury returned a verdict of guilty as to all three defendants — Manuel, Meynardo, and Alifonso Arredondo. At the request of defense counsel, the district court polled the jury following the taking of the verdict. One of the jurors responded, “No, that is not my verdict ... but I went along.” At that point, someone noticed that the court reporter was not present. The court reporter was then ■ brought in and the jury was repolled. This time, each juror was asked if he or she was in agreement with the verdict as to each of the three defendants separately. Each juror responded affirmatively, except the juror who had equivocated on the first polling. This juror, however, equivocated only as to co-defendant Arredondo. She specifically affirmed her belief that both Manuel and Meynardo Montemayor were guilty. The district court did not err in finding exactly which guilty verdict the equivocating juror found troublesome. As the Government states in its brief, to fault the Court for determining this fact is to blame the messenger for the message.
IV. Conclusion
We AFFIRM the conviction for conspiracy to distribute cocaine as to both defendants. The convictions on the remaining three counts are VACATED as to both defendants.
Notes
. Two named defendants, Benito and Reyes Montemayor had fugitated before the trial began. Matías Montemayor was allowed to sever his case and was tried separately. Both Salvador Flores and Eufracio Garcia pleaded guilty prior to trial.
. The Government’s case consisted primarily of Bowman’s testimony.
. At this time the trailer was in Des Plaines, Illinois.
. Macias was a handyman who was known as “the chemist.”
. There were two ranches in Cerralvo, one occupied by Matías and the other by Benito. Reyes also had a warehouse or farm near Cerralvo.
. Although at one point in his testimony Bowman stated that the basket contained brown paper packages filled with money or drugs, he later identified it as a “basket of cocaine.”
. The defendants have not argued that the concurrent sentence doctrine is inapplicable to the ■ instant case. Indeed, in their reply brief they state: “At sentencing the trial court did not mean to imply that only one conspiracy existed, but to the contrary that he intended to consolidate the four counts so that the sentence of each could run concurrently.
United States v. Gray,
. 21 U.S.C. § 841(b)(1)(A) permits a maximum of 15 years imprisonment and $25,000 fine for violations of §§ 841(a)(1) and 846. Similarly, 21 U.S.C. §§ 960(a)(3) and 960(b)(1) allow a maximum of 15 years in prison and $25,000 fine for a violation of §§ 959 and 963.
. The judge indicated that he was particularly concerned about (1) the possibility that counts 4 and 9 (conspiracy to distribute heroin and conspiracy to manufacture and distribute heroin) were basically the same charge and (2) the teachings of
United States v. Marable,
. If any room for doubt did exist, the Judgment and Probation/Commitment Order signed by the trial judge eliminates that doubt. The trial court’s “Finding & Judgment” recites:
Defendant has been convicted as charged of the offense(s) of conspiracy to distribute quantities of cocaine, 21:846 and 841(a)(1); conspiracy to distribute quantities of heroin, 21:846 and 841(a)(1); conspiracy to distribute quantities of marihuana, 21:846 and 841(a)(1); and conspiracy to manufacture quantities of heroin, 21:963 and 959, as charged in Counts 3, 4, 5 and 9 of the Indictment, respectively.
. This Court is well aware that mere presence and association with those participating in a conspiracy is insufficient to sustain a verdict of guilt.
United States v. Escobar,
. The concurrent sentence doctrine serves the interests of judicial economy.
. The Government might at some later date ask that the sentences be reimposed “in the interests of justice.” In such event, the convictions would then be subject to appellate review.
See United States v. Cardona,
. The indictment was meant to provide the basis for prosecution of Benito, Matías, and Reyes Montemayor as well as their brothers and several lesser players. The scope of the evidence presented at trial may have been narrowed because Matías’ trial was severed and Benito and Reyes fugitated.
. Their motion was made before Albers took the stand.
. The judge also pointed out to defendants that there could be no unfairness if the defense could obtain its own sweepings. As previously noted, defendants did not take the opportunity to do so.
. Given that the substances had been consumed through testing, the Government may not have been in “possession” of the substances within the meaning of the rule.
