Brian K. Thompson appeals from his conviction on numerous drug trafficking and money laundering charges and from the resulting sentence imposed by the district court. 1 We affirm.
I.
Thompson’s conviction stems from an investigation by federal and state authorities into a drug distribution and money laundering scheme centered in Kansas City, Missouri. Authorities first learned of Thompson’s involvement in the scheme in late 1994 through an undercover investigation conducted by Special Agent Albert Pisterzi of the Federal Bureau of Investigation (FBI). Pisterzi discovered that Thompson had been heavily involved in narcotics distribution since at least 1989 and was currently distributing 10 to 50 kilograms of cocaine per month. Pisterzi also obtained firsthand knowledge of Thompson’s drug activity, meeting with him several times in 1994 to discuss drug transactions and purchasing cocaine from him in November of that year.
Despite their knowledge of Thompson’s illicit conduct, authorities did not arrest
Apparently satisfied that they had exposed the entire conspiracy, authorities arrested Thompson on December 12, 1997, citing his 1994 sale of cocaine to Pisterzi as the basis for the arrest. Shortly thereafter, search warrants were executed at Thompson’s residence, his mother’s residence, an automobile dealership with which Thompson was affiliated, and three storage units controlled by Thompson. These searches yielded numerous items of evidence, including large quantities of cocaine and cash, numerous weapons, a drug scale, a currency counting machine, expensive automobiles, jewelry, and other luxury items.
Thompson was charged with conspiracy to possess and distribute cocaine and marijuana, five counts of distributing cocaine and marijuana, conspiracy to commit money laundering, five counts of money laundering, one count of possessing a firearm after a felony conviction, and one count of criminal forfeiture. Prior to trial, Thompson moved to suppress the wiretap evidence and the evidence seized from storage unit Jll, one of the three storage units searched in December of 1997. The district court 3 denied the motions. On June 12, 1998, a jury found Thompson guilty on all counts. He was sentenced to life imprisonment and was ordered to pay a special assessment of $1,200,000 and a fine of $2,000,000.
II.
Thompson first contends that we should set aside his conviction on three of the drug trafficking counts and all of the money laundering counts. He argues that the district court erroneously denied his motions to suppress the wiretap evidence and the evidence obtained from storage unit Jll and' that, absent this evidence, there is insufficient evidence to support his conviction on these counts. We review the district court’s denial of a motion to suppress de novo, and its factual findings for clear error.
See United States v. Fairchild,
A. Wiretap Evidence
Thompson contends that the wiretap evidence should have been suppressed because the application and affidavit used to secure the wiretap failed to establish the necessity for the wiretap that 18 U.S.C. § 2518(l)(c) requires. Section 2518(l)(c) provides that an application for an order authorizing a wiretap must include, among other things, “a full and complete statement as to whether or not other investigative procedures have been tried and failed or why they reasonably appear to be unlikely to succeed if tried or to be too dangerous.” This requirement seeks to insure “that wiretaps are not routinely
Our review of the supporting affidavit convinces us that the FBI’s wiretap application satisfies both the letter and the spirt of section 2518(l)(c). The affidavit recounts in detail the investigative procedures that authorities used during their two-year investigation of the conspiracy and explains why each of those methods failed to expose the full extent of the conspiracy. For example, the affidavit explains that physical surveillance was largely futile because Thompson was adept at evading authorities through the use of aliases and evasive driving tactics; pen registers were of limited use because Thompson registered his telephones in fictitious names and regularly changed telephone numbers; and cooperating informants were only minimally effective because all but one had ceased providing new information and the remaining informant was unable to identify the primary drug supplier or other key conspirators. The affidavit also explains why other traditional measures, such as grand jury subpoenas and search warrants, were not used, stating that such methods were avoided because of a fear that they would alert unknown conspirators to the investigation and thus make them even more difficult to apprehend.
The affidavit therefore establishes that authorities had employed several traditional investigative techniques for more than two years before applying for a wiretap and that those methods were insufficient to reveal the full conspiracy or the identity of several key conspirators. Such facts are sufficient to support a district court’s finding of necessity under section 2518(1)(c).
See Maxwell,
Although Thompson correctly points out that many of the reasons given in the affidavit for the ineffectiveness of traditional investigative techniques are common to most drug conspiracy investigations, this fact does not necessarily preclude a finding of necessity under section 2518(1)(c).
See United States v. Milton,
Thompson also contends that the district court erroneously failed to suppress evidence that was seized from storage unit Jll pursuant to a warrant authorizing a search of the storage unit and the seizure of a white 1992 Dodge minivan, a vehicle that authorities had linked to the conspiracy. He argues that the warrant was invalid because the affidavits submitted to secure the warrant specifically stated that the 1992 Dodge minivan was located in Jll, while the evidence upon which this statement was based, the testimony of Rick Jones, provided only that Jones saw Thompson drive a “white minivan” into Jll. Thompson contends that the affiants were not entitled to infer that the vehicle referred to by Jones was the 1992 Dodge minivan and that absent this inference there was no probable cause to search storage unit Jll, i.e., there was no reason to believe that Jll contained the 1992 Dodge minivan or any other contraband or evidence.
A warrant is supported by probable cause if “‘there is a fair probability that contraband or evidence of a crime will be found’ in the place to be searched.”
United States v. Mahler,
After reviewing the information that was available to the affiants at the time they prepared their supporting affidavits, we are satisfied that it was reasonable for the affiants to infer that the 1992 Dodge minivan was located in storage unit Jll. According to the affidavits, authorities obtained a seizure warrant on December 12, 1997, for a white 1992 Dodge minivan they had substantial reason to believe was involved in the conspiracy. Three days later, authorities interviewed Jones, a known associate of Thompson, who stated that Thompson often used Jll to store vehicles and that he had seen Thompson park a white minivan in that facility two weeks earlier. That same day, the manager of the storage facility stated that Jll was leased to Darrell Bostic, which authorities knew to be an abas used by Thompson, and that Jll contained a vehicle at that time. Thus, because a white 1992 Dodge minivan was linked to the conspiracy and because Thompson, an integral member of that conspiracy, was seen parking a white minivan in storage space Jll, it was reasonable for the affiants to infer that these two vehicles were one and the same.
We therefore conclude that Thompson’s motions to suppress evidence were properly denied and that his conviction on the challenged counts must thus stand.
III.
Thompson also challenges his sentence, contending that the district court improperly enhanced his offense level for his role in the offense, obstruction of justice, and the possession of a firearm in connection with a drug offense. These enhancements are based upon findings of fact, which we review for clear error.
See United States v. Baker,
A. Role in the Offense
Thompson first challenges the district court's enhancement for his role in the offense. The court found that Thompson was an "organizer or leader of a criminal activity that involved five or more participants" and therefore imposed a four-level enhancement pursuant to TJ.S.S.G. § 3B1.1(a). Thompson contends that such an enhancement was erroneous because there was insufficient evidence presented at trial from which the court could conclude that he was an organizer or leader of the conspiracy or any other criminal activi-
"The terms `organizer' and `leader' are to be broadly interpreted." United States v. Guerra,
The evidence established that Thompson played a key role in both the channeling of vast quantities of drugs into Kansas City and the distribution of those drugs to various dealers within the city. To promote the influx of narcotics into Kansas City, Thompson traveled to Texas to recruit a supplier, regularly organized the transport of large drug shipments from Texas, and often received and stored such shipments. To facilitate the distribution of drugs in Kansas City, Thompson provided drugs to dealers on credit so that they could sell without first buying the drugs themselves, recruited at least one person to deliver cocaine to those dealers, and controlled the price of the drugs he sold. In light of this evidence, there is no clear error in the district court's finding that Thompson was an organizer or leader of the conspiracy. See United States v. Brown,
B. Obstruction of Justice
Thompson also contends that the district court improperly imposed a two-level enhancement for obstruction of justice pursuant to U.S.S .G. § 3C1.1. Application note 4(a) of section 3C1.1 provides that a defendant's "threatening, intimidating, or otherwise unlawfully influencing a co-defendant, witness, or juror, directly or indirectly, or attempting to do so" warrants an enhancement for obstruction of justice. U.S.S.G. § 3C1.1, comment. (n.4(a)). "[A]n attempt to intimidate or threaten a witness, even if unsuccessful, is sufficient to sustain a two-level enhancement for obstruction of justice." United States v. Moss,
The presentence investigation report and the evidence adduced at trial reveal that Thompson directed acts of intimidation toward two prosecution witnesses, Michael Toner and Fred Rice. Prior to trial, Thompson telephoned Toner and demanded that Toner swear on the lives of his children that he had not cooperated with authorities. Thompson also warned Toner that he could expect a visit from Thompson once he was released from jail. At trial, Thompson directed similar threats to Rice, calling Rice derogatory names and
C. Possession of a Firearm
Finally, Thompson argues that the district court erroneously imposed a two-level increase to his base offense level pursuant to U .S.S.G. § 2Dl.l(b)(l), which provides for such an increase where a defendant possessed a firearm in connection with a drug offense. For this provision to apply, the government must “prove by a preponderance of the evidence that a weapon was present and that it was at least probable that the weapon had a nexus with the criminal activity.”
United States v. Newton,
The record is replete with evidence that weapons played a role in Thompson’s drug activity, including testimony that on two occasions Thompson possessed a firearm while he was actively engaged in drug transactions. In 1994, during the negotiation of a drug sale with Pisterzi, Thompson told the FBI agent that he was carrying a handgun and then patted his left hip to indicate its location. Two years later, Thompson fired a shotgun into the air while transferring drugs to one of his distributors. In light of this evidence, the district court did not clearly err in finding a sufficient nexus between Thompson’s drug activity and firearms so as to make section 2D1.1(b)(1) applicable.
The judgment and sentence are affirmed.
