Rаul Reyes appeals his conviction for conspiracy to possess cocaine with intent to distribute, in violation of 21 U.S.C. § 846. Reyes asserts the following grounds of error on appeal: (1) the search warrant affidavit lacked probable cause; (2) the execu *382 ting agents exceeded the scope of the search warrant; (3) certain handwritten notes and a cassette tape were erroneously admitted into evidence; and (4) the trial сourt improperly allowed a co-conspirator to testify at trial.
I. THE SEARCH WARRANT AFFIDAVIT
Reyes moved to suppress an audio cassette tape seized from his residence during the execution of a search warrant on November 2, 1984. The trial court held a hearing on the matter and denied the suppression motion. The affidavit in support of the search warrant was prepared by a special agent who had an extensive background in drug trafficking investigations. The affidavit provided specific information about Reyes’ participation in receipt of cocaine shipments and his role as a financial backer of certain drug transactions. In particular, the affidavit reсited the contention of William Ayala, a government informant, that he had delivered fifteen kilograms of cocaine to Reyes over two occasions, in October of 1983 and January of 1984. Ayala also referred to Reyes’ invоlvement in a drug transaction which had not been completed due to the seizure of a kilo and a half of cocaine at Las Cruces, New Mexico, on May 29, 1984. Furthermore, the affidavit mentioned the practice of various members of the conspiracy to maintain records of their associates.
Reyes argues that the search warrant affidavit was defective in two respects. First, he contends that the information contained in the warrant was stale, since five months elapsed between the Las Cruces seizure on May 29, 1984, and the issuance of the warrant on October 30, 1984. Second, Reyes claims that the affidavit did not refer to the conducting of any unlawful activities at Reyes’ residence, the place to be searched.
An affidavit in support of a search warrant must provide a substantial basis for determining the existence of probable cause; that there is a fair probability that evidenсe of a crime will be found in the place to be searched.
Massachusetts v. Upton,
Reyes complains that the information in the affidavit contained no specific link to his residence. The affidavit did indicate that participants in the conspiracy maintained records regarding their activities. It is reasonable to assume that certain types of evidence would be kept at a defendant’s residence and an affidavit need not contain personal observations that а defendant did keep such evidence at his residence.
Anthony v. United States,
II. THE SCOPE OF THE SEARCH WARRANT
Reyes contends that the agents executing the search warrant exceeded the scope of the warrant in seizing a cassette tape containing discussions concerning the sale and purchase of drugs. The search warrant authorized the seizure of “drug trafficking records, ledgers, or writings identifying cocaine customers, sources, [etc.].” (Tr. Vol. II, p. 45). The court below ruled that in modern times beсause *383 “business records are increasingly being kept on audio or video tape ... the law enforcement officers knew that the records that they were seeking might well be contained on [the] tape.” (Tr. Vol. II, pp. 68-69).
The trial court correctly recognized that in the age of modern technology and commercial availability of various forms of items, the warrant could not be expected to describe with exactitude the precise form thе records would take.
See, e.g., United States v. Thompson,
III. ADMISSION OF EVIDENCE
Reyes argues that the trial court improperly admitted into evidence taped conversations between Reyes and his сoconspirators and certain handwritten notes. Absent an abuse of discretion, a court of appeals is bound to uphold a trial court’s rulings on evidentiary matters.
United States v. Cooper,
Reyes maintains that the notes were not written by him and were inadmissible as hearsay. The thrust of Reyes’ argument is that the documents were not properly authenticated pursuant to the requirements of Rule 901 of the Federal Rules of Evidence. The handwritten notes admitted into evidence were neithеr signed nor dated. Further, Reyes suggests that a comparison of the handwriting in the notes to his handwriting established that the notes were not authored by him.
Rule 901(b)(4) of the Federal Rules of Evidence permits authentication by means of “[a]ppearance, contents, substance, internal patterns, or other distinctive characteristics, taken in conjunction with circumstances.” The contents of the notes included the name of the defendant and initials of his co-consрirators, notations of numbers of ounces, subtractions and additions of six-digit figures, and phone numbers. (Tr. Vol. V, pp. 423-438). The notes were seized from Reyes’ residence. The source of the notes and the correspondence of informаtion contained in the notes to members of the conspiracy provided ample foundation for their admissibility. Moreover, the contents of the notes indicated that they were written by someone involved in the conspiracy.
See United States v. Drougas,
Reyes also complains of error in the admission into evidence of taped conversations between himself and other coconspirators. Reyes argues that the trial court should not have admitted the tape because no date was established for the conversations. Testimony concerning Reyes’ girlfriend’s birthdate and pregnancy indicated that the tape wаs prepared on June 30, 1983. (Tr. Vol. VI, pp. 750-53). Moreover, by the time the tape was played for the jury, the government had introduced significant evidence of the conspiracy. The conversations concerned the distributions of nаrcotics. The Court finds the tape was properly authenticated and admitted in evidence of the conspiracy.
See United States v. Brewer,
IV. CO-CONSPIRATOR’S TESTIMONY
At trial the government informant William Ayala was permitted to testify to certain matters that co-conspirаtor Roberto Ramirez told him about Reyes’ involvement
*384
in the conspiracy. Reyes argues that the co-conspirator’s testimony was improperly admitted under Rule 801(d)(2)(E) of the Federal Rules of Evidence and that the trial court failеd to follow the order of proof required for admission of co-conspirator’s testimony by
United States v. Peterson,
Rule 801(d)(2)(E) provides that “a statement by a coconspirator of a party during the course and in furtherance of the conspiracy” is not hearsay. Reyes’ contention is that the statements admitted were not made “in furtherance” of the conspiracy. According to Reyes, a statement can be “in furtherance” of a conspiracy only if it is both intended tо promote the conspiracy and did in fact have the effect of promoting the conspiracy.
This Circuit has no talismanic formula for ascertaining when a conspirator’s statements are “in furtherance” of the cоnspiracy.
See United States v. Davis,
Ayala testified that Ramirez had told him that Reyes was sponsoring the purchase and distribution of cocaine. Further, Ramirez had explained to Ayala that Reyes’ role in the organization was that of an investor or financial backer. Since Ramirez’ statements explained events important to the conspiracy to one of its members in order to facilitate the conspiracy, the Court finds that the statements were “in furtherance” of the conspiracy.
Finally, Reyes contends that the ordеr of proof recommended in
United States v. Peterson
for the admission of hearsay statements of co-conspirators was not followed in this case. Reyes complains that his confrontation rights were violated since hearsay and nonheаrsay testimony were intermingled and because the government had not established Reyes’ participation in the conspiracy until after some of the hearsay had been admitted. In
United States v. Rivera,
In United States v. Peterson,611 F.2d at 1330 , we stated that although we determined it was preferable, whenever possible, to require the Government to first introduce independent proof of the conspiracy and subsequently to establish the connection of the defendant with it before admitting hearsay declarations, there was an exception recognized where it was not reasonably practicable to require the showing to be made before admitting the evidence; in such a case the trial judge could admit the hearsay statements, subject to their being connected up later.
In this case, the trial judge was aware of the
Peterson
decision and the preferred method of proоf. (Tr. Vol. VI, p. 628). The record indicates that the court admitted the statements conditionally, subject to their being connected up. (Tr. Vol. IV, p. 161). At the close of the government’s
*385
case, the judge found by a preponderance of thе evidence that the United States had established with independent evidence the existence of the conspiracy and Reyes’ participation in it. (Tr. Vol. VI, p. 627.) Under these circumstances, this Court finds that no reversible error was committed.
See United States v. Harenberg,
No reversible error has been demonstrated. Accordingly, the conviction of the defendant is AFFIRMED.
