Defendants Diane and Edwin Turner appeal their jury convictions for conspiracy to distribute cocaine, importation of cocaine, aiding and abetting the importation of cocaine, and conspiracy to import cocaine in violation of 21 U.S.C. §§ 846, 952(a), 18 U.S.C. § 2, and 21 U.S.C. § 963, respectively. On appeal, defendants argue that the district court erred in (1) not conducting an evidentiary hearing pursuant to
Kastigar v. United States,
Diane and Edwin Turner operated the Hawk’s Nest Resort on Cat Island in the Bahamas. The resort contained both an airstrip and a marina and was used as a drop-off location for cocaine being trans *223 ported from Colombia to the United States. Typically, cocaine would be flown in from Colombia and loaded onto small boats bound for private residences in Florida. The Turners sometimes supervised the landing and unloading of these planes. The Turners required payment of $250,000 to $300,000 for each plane which landed on their airstrip.
Defendants Diane and Edwin Turner raise four issues on appeal. First, defendants argue that the district court erred in not conducting a Kastigar hearing in order to determine whether the government’s evidence concerning the Turners’ illegal activity was obtained independently of their prior “immunized” testimony. Apparently, Edwin Turner testified before a grand jury sitting in the Southern District of Florida on March 23, 1988, and had also cooperated with Florida State Law Enforcement Officials. An affidavit submitted by Roger Colton, the Turners’ attorney in Florida, represented that Edwin Turner was promised “criminal immunity within the Southern District of Florida. It [the immunity] could not go outside or bind any other district other than the Southern District of Florida.” The affidavit went on to note that “[i]t would be a derivative use immunity in that nothing that Mr. Turner said would be disseminated to any other agencies that could ever be used against him.” With respect to the immunity granted by the State of Florida, it was characterized as “use immunity” by William G. Wolfe, Special Agent for the Florida Department of Law Enforcement. These two affidavits were the only documents introduced concerning the “immunity” granted to the Turners. The affidavits do not indicate that Diane Turner was ever granted any type of immunity. However, at trial Attorney Colton testified that Diane Turner was granted the same type of immunity as Edwin Turner by federal officials in the Southern District of Florida.
The government argues that the dictates of
Kastigar
are not implicated in this case because the Turners were never granted the requisite
statutory
immunity. The “immunity” which the Turners were granted in the Southern District of Florida by the federal prosecutor is sometimes referred to as “pocket immunity.”
See United States v. Friedrick,
Essentially, the “immunity” the Turners received in the Southern District of Florida was nothing more than a promise on the part of the federal prosecutor that they would not be charged in that district and that their testimony would not be disseminated to other government agencies. Such promises of “immunity” are contractual in nature and do not bind other parties not privy to the original agreement.
See United States v. Peister,
In
Kastigar v. United States,
The district court was not required to hold a
Kastigar
hearing with respect to the “immunity” granted to the Turners by the federal prosecutor. The federal prosecutor does not have any authority to immunize testimony absent compliance with the requirements of the federal immunity statute. He does, however, possess sole discretion in his particular district with respect to the decision to prosecute.
See United States v. Nixon,
The immunity Edwin Turner received from the State of Florida presents a somewhat different situation. The Florida immunity statute provides:
No person who has been duly served with a subpoena or subpoena duces te-cum shall be excused from attending and testifying or producing any book, paper, or other document before any court having felony trial jurisdiction, grand jury, or state attorney upon investigation, proceeding, or trial for violation of any of the criminal statutes of this state upon a ground or for the reason that the testimony or evidence, documentary or otherwise, required of him may tend to convict him of a crime or to subject him to a penalty or forfeiture, but no testimony so given or evidence so produced shall be received against him upon any criminal investigation or proceeding. Such testimony or evidence, however, may be received against him upon any criminal investigation or proceeding for perjury committed while giving such testimony or producing such evidence or for any perjury subsequently committed.
Fla.Stat. § 914.04 (1989). This statute has been interpreted as being self-executing; thus, the statute automatically grants use immunity to one who testifies under the circumstances it delineates.
Jenny v. Florida,
In
Murphy v. Waterfront Comm’n of New York,
Once a defendant demonstrates that he has testified, under a state grant of immunity, to matters related to the federal prosecution, the federal authorities have the burden of showing that their evidence is not tainted by establishing that they had an independent, legitimate source for the disputed evidence.
Id.
at 79, n. 18,
The government argues that it met its burden of establishing an independent source by submitting affidavits in which federal officials involved in the Turner investigation disclaimed any prior knowledge of Edwin Turners’ immunized testimony. These affidavits, however, are insufficient to meet the dictates of
Kastigar;
the government must identify the independent source of the evidence used against Edwin Turner.
See United States v. Overmyer,
Therefore, with respect to Edwin Turner, remand is necessary for the limited purpose of allowing the district court to ascertain whether Edwin Turner’s testimony in the Florida state criminal proceedings was compelled by subpoena. If Turner demonstrates that his testimony was compelled, the district court must next determine whether the evidence used at trial against Edwin Turner was in fact derived from a legitimate source wholly independent of his immunized testimony.
Kastigar,
The Turners next argue that the indictment against them should have been dismissed because the government breached its agreement not to prosecute them. This argument deserves little attention, since the government only promised not to prosecute them in the Southern District of Florida. This promise was kept. The Turners’ attorney in Florida testified at trial that “[i]t was very, very clear that the immunity, only applied to the Southern District of Florida, if the Assistant U.S. Attorney ... made that clear once, he must have made it clear at least half-a-dozen times.” Furthermore, even if the Turners were promised that they would not ever be prosecuted by the government, it is unclear that a United States Attorney in one judicial district has the power to bind another United States Attorney in another judicial
*226
district.
See United States v. Robison,
The Turners next argue that the district court abused its discretion when it denied defendants’ motion for change of venue. The grant or denial of a motion for change of venue rests within the sound discretion of the trial court and will not be disturbed absent a clear abuse of discretion.
United States v. Williams,
Finally, the Turners argue that the district court erred in not granting a mistrial after it was discovered that the jury utilized a dictionary after their request for one was denied by the judge. During their deliberations, the jury requested a dictionary from Judge Friedman, who was substituting for Judge Cohn. Judge Friedman denied their request. When Judge Cohn returned he informed counsel that a dictionary was found in the jury room the night before. There pieces of paper had been inserted at the pages beginning with M, 0, and S. Defense counsel opined that the jury had been looking up the definitions of “manager,” “organizer,” and “supervisor.” Defense counsel all joined in a motion for a mistrial.
The district court refused to grant a mistrial and instead it summoned the jurors and instructed them that they had improperly consulted the dictionary and were to disregard any definition they had read and should interpret the relevant words in a “common-sense fashion.” He further instructed them that if they had reached a verdict on any count through the use of a definition they looked up in the dictionary, they were to re-deliberate on that count using the common meaning of the words. The judge then asked the jury if there was anyone who could not continue to deliberate under these conditions. No one responded, so the judge sent the jury back to continue its deliberations.
This court was presented with a similar situation in
United States v. Griffith,
[wjhen a jury makes unauthorized use of a dictionary, the trial judge should determine whether the jury actually substituted the dictionary definition of a legal term for that given in the instructions. If any jurors substituted the dictionary definitions, the court should determine whether any use of the dictionary resulted in prejudice to the defendant.
Id. at 1252. The fact that the district court judge found slips of paper beginning at M, O, and S provides compelling evidence that the jury probably did use the dictionary to obtain definitions to legal terms. The judge did attempt to rectify the dictionary problem according to the teaching of Griffith. Although he did not follow the procedure outlined in Griffith, he did attempt to insure that no defendant was prejudiced by the jury’s exposure to the dictionary. In *227 stead of determining whether the jury had substituted a dictionary term for a legal term, the judge simply instructed the jury to not use the dictionary definition and sent them back to deliberate. He did ask, however, if any juror could not use the normal common-sense meaning of the words in an attempt to guard against potential prejudice. Because the trial judge took the necessary steps to insure against any potential prejudice resulting from the jury’s use of the dictionary, his decision not to grant a mistrial was not an abuse of discretion.
Therefore, we affirm the conviction of Diane Turner and remand the conviction of Edwin Turner to the district court.
