A jury сonvicted Steve Buchanan of one count of attempting to manufacture methamphetamine in violation of 21 U.S.C. § § 841(a)(1) and 841(b)(1)(B). Prior to trial, the district court 1 denied Buchanan’s motion to suppress certain evidence. Buchanan appeals his conviction, arguing that the district court erred in denying his motion to suppress because the affidavit supporting the warrant failed to establish the reliability or credibility of the two informants and misrepresented the statements Buchanan had made in a recorded telephone call. Buchanan also claims that the district court’s jury instructions constructively amended the Indictment by omitting the word “attempt” from an instruction, that the Indictment failed to state an offense because it did not specifically cite the attempt statute, and that there was an impermissible variance between the Indictment and the proof at trial. We affirm.
I. Background
On February 13, 2006, the South Dakota Division of Criminal Investigation received an unsolicited phone call concerning alleged drug activity in Custer, South Dakota. The call was referred to Agent Lyle Tolsma who did nоt know and had not had any previous contact with the caller. The caller, whom Tolsma deemed a “source of information” (“SOI”), identified herself by first name, indicated that she had been to Buchanan’s house three days earlier, and alleged that Buchanan had offered her methamphetamine. The SOI also alleged a second person — a woman Tolsma later identified as a confidential informant (“Cl”) — was involved in manufacturing methamphetamine with Buchanan.
During the call, the SOI informed Tolsma she was familiar with the appearance of methamphetamine and had been around it several times. The SOI described seeing approximately half of a gram of crystal methamphetamine on an aluminum smoking apparatus at Buchanan’s house and stated that she was forced to leave the house because of the strong chemical odor. Tolsma testified that methamphetamine manufacturing produces a noticeable smell which, in some cases, can be detected a block away.
Around noon on February 14, 2006, Tolsma, joined by Agent Stevе Ardis, conducted a “knock and talk” at Buchanan’s home to investigate the SOI’s allegations. Buchanan refused to let the agents into his house, claiming that it was messy. Buchanan made no incriminating statements, and Tolsma testified that he smelled no odor indicative of methamphetamine manufacturing.
*559 After speaking with Buchanan, Agents Tolsma and Ardis went to the Cl’s house to conduct another knock and talk. They told the Cl that they were investigating allegations that she was involved in manufacturing methamphetamine with Buchanan. The Cl confirmed that Buchanan wаs making methamphetamine and that, since October 2005, she had provided him approximately fifty packets of pseudoephedrine, a drug used to produce methamphetamine. The Cl indicated that she had received methamphetamine from Buchanan in exchange for the pseudoephedrine. She also stated that she had smoked methamphetamine with Buchanan three days prior and that she had last seen Buchanan when she delivered pseudoephedrine to him the previous night. The Cl also itemized objects Buсhanan was using to produce the drug in his home.
Tolsma and Ardis told the Cl that if she cooperated in their investigation they would speak to the prosecutor and that her cooperation would “go a long ways” toward helping her. The Cl then agreed to conduct a recorded phone call with Buchanan, which they conducted that same day.
During the recorded phone conversation, Buchanan cautioned the Cl of the agents’ visit to his house and commented that state investigators were “probably listening in.” Buchanan and the Cl thеn engaged in a discussion of who might have informed law enforcement that he was manufacturing methamphetamine. Later in the conversation, Buchanan stated, “[Tjhere’s a bunch of stupid [expletive] people around that you know, they get in trouble and then they try and get us in trouble .... so hell, I’m not doing anything wrong.” The Cl asked Buchanan, “Do you think you are ok?” Buchanan replied, “Yeah, yeah, yeah, like I said you know, hey. It is scary but like I said, I ain’t done nothing so I ain’t worrying about it but I do have to clean up my garbage cause if they come into my house and bunch of people like that
Buchanan told the Cl that he had refused to let the agents into his house and commented, “I gotta clean up my you know, key ends, and garbage and stuff I got laying all over my house and stuff you know and make it look a little more presentable in case somebody comes in. I’d hate to, you know.” At one point, Buchanan and the Cl engaged in an indirect discussion about the whereabouts of an unnamed item. The Cl asked, “[W]ell what about me?” Buchanan replied, “Don’t worry about that, it’s gone.” He later stated, “Yeah, it’s gonе. You know what I mean, you can’t piss around and stuff so ... I imagine they are probably trying to get a warrant and all this [expletive] right now so.... ” Later the Cl asked directly, “And where did you put it?” Buchanan replied “I haven’t you know, time to get rid----” The Cl interjected, “I know, but where?” Buchanan replied, “It ain’t at your place so I don’t know____”
Approximately a half hour after the call, law-enforcement agents, including Agent Tolsma, entered Buchanan’s house and secured the residence to ensure no evidence was destroyed or removed. Tolsma then рrepared an application and affidavit in support of a search warrant and read them over the phone to a state magistrate. Tolsma detailed the information the SOI had conveyed, but did not tell the state magistrate that the SOI had not given her full name, that he did not know her, or that he had not had any previous contact with her. While providing details of his conversation with the Cl, Tolsma failed to state that he had no previous connection to the CI. Additionally, Tolsma indicated that he had visited Buchanan, but did not state that he had been physically present both inside and outside Buchanan’s house with *560 out smelling a methamphetamine odor. Tolsma characterized Buchanan’s statements in the recorded phone call as follows: “Buchanan advised the Cl that he ... is currently in the process of cleaning out his residence, referring to the clandestine equipment and chemicals.” (emphasis added). Buchanan, however, had never directly referenced the “clandestine equipment” or “chemicals” in the recorded call.
Based on Tolsma’s application and affidavit, the state magistrate granted a search warrant, and a subsequent search revealed many incriminating items. Buchanan was then indicted for attempting to manufacture methamphetamine. The Indictment read:
On or about February, 2006, at Custer, in the District of South Dakota, the defendant, Steve Buchanan, did knowingly and intentionally attempt to manufacture five grams or more of actual methamphetamine, a Schedule II controlled substance, all in violation of 21 U.S.C. §§ 841(a)(1) and 84 1(b)(1)(B).
The Indictment, however, did not include a statutory reference to 21 U.S.C. § 846, which criminalizes the attempt to manufacture a controlled substance. See 21 U.S.C. § 846.
Prior to trial, Buchanan filed a motion to suppress the evidence obtained during the search. A magistrate judge held a
Franks
hearing to determine the validity of the search warrant and issued a report and recommendation that the district court deny Buchanan’s motion.
See Franks v. Delaware,
While the Indictment alleged a conspiracy “[o]n or about February 2006,” the Government introduced evidence dating back to the spring of 2005 and established that Buchanan had expressed interest in learning to manufacture methamphetamine and had sought instruction from books and friends. Buchanan did not object to the introduction of this evidence. At the close of evidence, however, he made a Rule 29 motion for a judgment оf acquittal, arguing that he had been prejudiced by an impermissible variance between the indictment and the facts established at trial. See Fed.R.Crim.P. 29. The district court denied Buchanan’s motion.
Ultimately, the jury convicted Buchanan of one count of attempting to manufacture methamphetamine in violation of § 841. The district court sentenced him to eighty months’ imprisonment and four years’ supervised release. This timely appeal followed.
II. Motion to Suppress
Buchanan argues that the district court erred by failing to grant his motion to suppress. He claims that the SOI’s and *561 Cl’s аllegations were hearsay and lacked corroboration, thus resulting in a lack of probable cause sufficient to support the issuance of a search warrant. He also argues that Tolsma recklessly misrepresented the nature of Buchanan’s statements in his affidavit and omitted certain facts that demonstrated the absence of probable cause.
In reviewing the denial of a motion to suppress, “[w] e review the district court’s factual findings for clear error and its legal determinations de novo.”
United States v. Lucas,
A. Probable Cause
Buchanan first claims that the Cl and SOI did not provide sufficiently credible or reliable information to establish probable cause. Probable cause to search exists if “there is a fair probability that contraband or evidence of a crime will be found in a particular place.”
Illinois v. Gates,
When reviewing a probable cause finding, the duty of this court is simply to ensure that the judicial officer that authorized the search had a “substantial basis for concluding that probable cause existed,”
Gates,
Contrary to Buchanan’s claim, we believe the information from the Cl and SOI was sufficiently reliable to establish probable cause. In determining whether information is reliable, wе have set forth various factors to consider. In
United States v. Jackson,
An informant may also be considеred reliable if the information he or she supplies “is at least partially corroborated” by other sources.
Humphreys,
Here, as the district court noted, the statements provided by both the Cl and the SOI were based on their firsthand observations and knowledge rather than rumor or innuendo,
see Jackson,
Finally, the information the SOI provided to Tolsma was corroborated by the information the Cl provided. Like the specific and consistent details of the second informant that reciprocаlly corroborated the first informant in
Fulgham,
the Cl in this case gave specific details that were consistent with the SOI’s allegations.
See Fulgham,
Buchanan argues that the reliability of the informants based on reciprocal corroboration fails because it does not meet an exaggerated level of specific verification, and he points to certain, specific allegations that were not plainly corroborated. We have addressed specific, technical contentions like this before. In
Reivich
we stated, “Such emphases typify the ‘excessively technical dissection of informants’ tips’ and the ‘judging [of] bits and pieces of information in isolation against ... artificial standards’ against which the Supreme
*563
Court cautioned in
Gates
and
Upton.” Reivich,
B. Misstatements and Material Omissions in the Affidavit.
Buchanan also claims that the district court erred in denying his suppression motion because Tolsma recklessly misrepresented the nature of Buchanan’s statements in Tolsma’s warrant аpplication and, thus, there was no basis for probable cause. An affidavit in support of a warrant must contain statements that are truthful.
See Franks,
Here, the district court found no evidence that Tolsma acted untruthfully or recklessly in preparing his affidavit and application for a search warrant, аnd the record demonstrates that the district court’s finding was not clearly erroneous. The affidavit was written in haste and spoken over the phone. Thus, as the district court recognized, “Any mistake Tolsma may have made in this regard would have been an understandable mistake, given the context of the conversation in which Mr. Buchanan’s statement was made.” There is no indication in the record that Tolsma was attempting to mislead the state magistrate nor that Tolsma had “serious doubts” about his statements or had “obvious reason” to doubt the aсcuracy of what he was relaying.
Buchanan argues, however, that the procedure used by the state magistrate to assess probable cause in this case violated the Fourth Amendment. He claims the state magistrate adopted Tolsma’s interpretation of Buchanan’s statement, and in so doing, “put the cart before the horse” because he effectively allowed Tolsma to assess the presence of probable cause. This is essentially a reiteration of Buchanan’s challenge to the validity of the warrant affidavit. Our Fourth Amendment inquiry requires only that the evidence as a whole provide a substantial basis for the finding of probable cause.
See Gates,
III. Indictment Claims
In addition to his motion-to-suppress claims, Buchanan raises several arguments relatеd to his Indictment. He claims that the district court’s jury instructions con *564 structively amended the Indictment to include a charge of actual manufacturing of methamphetamine. He also claims there was an impermissible variance between the Indictment date and the proof established at trial. Finally, he claims the Indictment was insufficient because it did not cite the statute criminalizing attempt. We find Buchanan’s claims unavailing.
A. Constructive Amendment
Buchanan first claims that the district court’s jury instructions constructively amended the Indictment. “A constructive amendment occurs whеn the essential elements of the offense as charged in the indictment are altered in such a manner that ... the jury is allowed to convict the defendant of an offense different from or in addition to the offenses charged in the indictment.”
United States v. Whirlwind Soldier,
Here, the Indictment charged Buchanan with an “attempt to manufaсture” methamphetamine. Buchanan argues that the jury instructions constructively amended the indictment because instruction six omitted the word “attempt” and instead read: “The indictment charges the defendant with manufacturing a controlled substance in violation of 21 U.S.C. § 841(a)(1).” We disagree with Buchanan. The jury instructions repeatedly included references to the charge of attempt to manufacture methamphetamine. Instruction five, for example, informed the jury that Buchanan was charged with “knowingly and intentionally attempting] to manufacture ... methamphetamine.” Instruction eight stated: “[t]he crime charged in the indictment is an attempt to manufacture methamphetamine.” Additionally, although the district court inadvertently omitted the word “attempt” from the beginning section of instruction six, that instruction continued to inform jurors that 21 U.S.C. § 846 “provides that [a]ny person who attempts ... to commit any offense defined in this subchapter [which includes 21 U.S.C. § 841(a)(1)] shall be subject to the same penalties as those prescribed for the offense.” More importantly, the court also instructed the jury of the elements оf “attempt to manufacture” in instruction seven, and explained those elements in instruction eight.
Given these instructions, we believe that the jury instructions clearly informed the jury of the essential elements of the crime of attempting to manufacture methamphetamine.
See Whirlwind Soldier,
B. Variance of the Indictment
Buchanan also argues that the evidence presented at trial constituted a variance of the Indictment. A variance arises when the evidence presented proves facts that are “materially different from those alleged in the indictment.”
United States v. Begnaud,
Here, the Indictment charged Buchanan with attempt to manufacture methamphetamine “on or about February 2006.” The offense of attempt to manufacture methamphetamine did not require the Government to prove the Indictment date as an element of the crime. Rather, the charge required the Government to prove that Buchanan carried out substаntial steps toward the manufacture of methamphetamine.
United States v. Beltz,
C. Sufficiency of Indictment
Buchanan’s final claim is that his Indictment failed to state an offense because it did not directly cite 21 U.S.C. § 846, which criminalizes attempt. Failure to raise a challenge to an indictment prior to trial generally constitutes a waiver.
United States v. Davis,
“An indictment is sufficient if it fairly informs the accused of the charges against him and allows him to plead double jeopardy as a bar to a future prosecution.”
United States v. Mallen,
Buchanan has not indicated how the omission of the statutory citation misled him. A reasonable construction of the Indictment indicates that it charged the offense of attempt to manufacture a controlled substance, and the words “did knowingly and intentionally attempt to manufacture” clearly set forth the еlements of the intended charge of attempt. We therefore hold that the indictment fairly informed Buchanan of the charges against him and allows him to plead double jeopardy as a bar to a future prosecution for attempt to manufacture methamphetamine. The Indictment was therefore sufficient.
IV. Conclusion
For the foregoing reasons, we affirm the judgment of the district court.
