Jeffrey H. Collins raises numerous issues challenging his conviction and life sentence for conspiring to distribute and for possession with intent to distribute more than 500 grams of methamphetamine. For the reasons herein, we affirm the district court. 2
I.
Because Collins challenges the sufficiency of the evidence used to convict him, we summarize the evidence adduced at trial. Seven people familiar with Collins’s drug sales testified against him. These witnesses-Thomas Horan, Brenda Stewart, Pamela Erickson, Douglas Rydberg, James Hald, Susan Gomez, and Matthew Matejka-testified that Collins sold them methamphetamine at various times and in various amounts during the two-year period charged in the indictment, sometimes accepting property rather than money in exchange for methamphetamine. 3
In addition to the regular drug transactions, these witnesses testified about Collins’s related drug activities. Stewart testified that she committed forgeries to obtain cash or merchandise to pay for drugs. Collins would place an “order,” and Stewart would go to a store and fraudulently acquire the item.
Rydberg testified that he usually bought methamphetamine from Hald, who first bought the drugs from Collins. Rydberg testified that he would either buy the drugs “on credit,” or pool several people’s *677 money to buy a larger amount of methamphetamine at a lower price. Rydberg testified that Hald was the “middleman.” Hald verified that Collins approved reselling the methamphetamine because Collins would not sell to strangers. Hald also testified that he once traded a Plymouth Sundance automobile to Collins for an ounce of methamphetamine, and at trial, the government offered the car title to show the change in ownership from Hald to Collins. Gomez, who had known Collins since 1994, also would pool her money with other customers’ money to buy larger quantities at lower prices. She testified that she would “skim some off the top” from the purchases for herself.
Stewart, Erickson, Hald, and Matejka testified about an incident at Matejka’s residence that resulted in Matejka’s incarceration for possession of methamphetamine allegedly belonging to Collins. Ma-tejka testified that on February 6, 2001, Collins went to Metejka’s house to be paid for a drug deal. While there, the police entered the house to serve an arrest warrant on Matejka. Matejka was charged after the police found him with 49.5 grams of methamphetamine in the basement, drugs that Matejka claimed belonged to Collins. Hald testified that Matejka told him that Collins framed him for the methamphetamine the police found in the raid. Stewart also testified that Collins sent a letter to her while she was in jail indicating that Collins refused to admit that the drugs he had taken to Matejka’s house were his.
Emma Chance, the owner of Bart’s Motel in Council Bluffs, testified that Collins rented a room at the motel sixteen days in January, February, and March of 2001, paying cash for each transaction. Ron Riethmuller, records administrator for the Nebraska Department of Correctional Services, testified that during the time-frame in the indictment, Collins was on “work release.” Consequently, no one from the corrections department supervised or monitored Collins during the day as long as he returned to the work-release center at night. Riethmuller also noted that Collins was paroled on February 25, 2000, but was returned to the correctional facility on August 14, 2000. However, the state discharged Collins from the correctional service on January 4, 2001.
Several police officers testified about Collins’s behavior at the time of his arrest on September 27, 2001. The officers testified that Collins attempted to escape by jumping into his car and leading the police on a chase. During the chase, Collins threw a package out of the car. The police recovered the package and discovered that it contained 16.1 grams of methamphetamine.
Based on above evidence, a jury convicted Collins of conspiracy to distribute and possess with intent to distribute methamphetamine. The court then sentenced Collins to fife in prison. Collins appeals his conviction and sentence.
II.
A. Sufficiency of the Evidence
Collins first argues that there was insufficient evidence to convict him of conspiracy because the evidence merely established a buyer-seller relationship between Collins and numerous individual» without showing a conspiracy to distribute drugs. He argues that the jury “misinterpreted” the facts and the jury instructions, and that while he may have associated with convicted felons and drug dealers, the evidence does not support a finding that he conspired with them to distribute drugs.
“The standard of review of an appeal concerning sufficiency of the evidence is very strict, and the verdict of the jury should not be overturned lightly.”
*678
United States v. Crossland,
To prove that a defendant conspired to distribute drugs under 21 U.S.C. § 846, the government must prove (1) that there was a conspiracy, i.e., an agreement to distribute the drugs; (2) that the defendant knew of the conspiracy; (3) that the defendant intentionally joined the conspiracy.
United States v. Jones,
Based on the facts established at trial, the evidence supports Collins’s conviction for conspiracy. The evidence establishes that Collins himself would not sell methamphetamine to strangers, but instead would sell substantial amounts of methamphetamine to Hald or Rydberg, for example, who would resell the drugs to numerous individuals. The evidence proves that Collins knowingly participated in and promoted this scheme. Furthermore, Collins’s challenge to the veracity and credibility of the various witnesses is to no avail — questions of credibility are the province of the jury.
See United States v. Chavez,
B. Quantity of Drugs Attributed to Collins
Collins next argues that the district court and the jury erroneously attributed more drugs to Collins than he could have sold in the time frame provided in the indictment. Collins argues that it was impossible for the witnesses collectively to have bought more than 500 grams of methamphetamine from him because he was incarcerated during seven months in 2000. Collins provides no legal support for his argument.
The government responds that the sentencing judge was the same judge who presided over trial, and that in such cases, the sentencing court is not required to hold an evidentiary hearing to resolve any factual challenges such as drug quantity.
See United States v. Wiggins,
A sentencing court’s quantity calculations are factual findings and therefore, are reviewed for clear error.
United States v. Jimenez-Villasenor,
*679
Collins’s “impossibility” argument fails. The evidence proves that the witnesses knew of Collins’s incarceration and testified that they bought drugs either from him or from Collins’s middlemen when he was not incarcerated. In addition, Collins’s challenge is based (in part) on his attack against the witnesses’ credibility and their recall regarding the amount of drugs he sold to them. We leave this credibility issue for the jury.
Chavez,
C. Sentence Illegality Under Apprendi and the Eighth Amendment
Collins next argues that the district court assessed an excessive and illegal sentence under
Apprendi v. New Jersey,
1. Alleged Apprendi Violation
In
Apprendi,
the United States Supreme Court stated, “Other than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
2. Eighth Amendment Violation
Collins also asserts that the imposition of a mandatory life sentence is cruel and unusual punishment in violation of the Eighth Amendment. He claims that the sentence is “grossly disproportionate” to the crime and argues that this was a “simple drug conspiracy” that, when compared with similar crimes, did not warrant a life sentence.
The Eighth Amendment “forbids only extreme sentences that are ‘grossly disproportionate’ to the crime.”
Harmelin v. Michigan,
We have held that mandatory minimum penalties for drug offenses do not violate the Eighth Amendment’s prohibition of cruel and unusual punishments.
United States v. Mendoza,
In
United States v. Prior,
Such a proportional analysis is only appropriate after an initial comparison of the crime to the sentence for which it is imposed leads to an inference of gross disproportionality. United States v. Johnson,944 F.2d 396 , 409 (8th Cir.) (relying on Harmelin), cert. denied,502 U.S. 1008 ,112 S.Ct. 646 ,116 L.Ed.2d 663 (1991). We have noted that the possession of narcotics with the intent to distribute is an offense “at the root of some of the gravest problems facing our country. The ‘fruit’ of the drug plague is everywhere; it fills our jails, our courts, our streets, and our nurseries.” United States v. Meirovitz,918 F.2d 1376 , 1381 (8th Cir.1990), cert. denied,502 U.S. 829 ,112 S.Ct. 101 ,116 L.Ed.2d 71 (1991). Prior’s three previous convictions indicate that he has been involved in drug distribution for many years, and his actions have furthered the spread of this plague.
Prior,
Under these facts, Collins’s two prior felonies used to enhance this sentence were also drug crimes. 4 As in Prior, the repeated nature of similar crimes particularly lends the matter to the enhancement provision of § 841(b) and does not warrant a finding of disproportionality under the Eighth Amendment. Collins’s constitutional claim thus cannot succeed.
D. Mistrial/New Trial for Sequestration Violation
Collins next argues that the district court erred in refusing to grant a mistrial or a new trial after two alleged violations of the court’s sequestration order. Collins alleges that the first violation occurred when the United States Marshall Service placed prosecution witnesses Rydberg and Hald in the same holding cell as they awaited their turns to testify. Collins claims that the second violation occurred when Sheriff Deputy Robert Jones, prior to being called to testify, entered the courtroom during the testimony of Emma Chance, another prosecution witness. Collins argues that there was “manifest necessity” for granting a mistrial or a new trial under these circumstances, and nothing short of mistrial or a new trial could have cured the violations.
Sequestration of most witnesses is mandatory when requested,
see
Fed.R.Evid. 615, but the district court is granted wide latitude in implementing sequestration orders, and the standard of review is abuse of discretion.
United States v. Vallie,
Collins’s first allegation involves Hald and Rydberg’s confinement in the same holding cell during the trial. He cites
United States v. Greschner,
Collins’s second claim turns on Officer Jones’s pre-testimony presence in the courtroom when Chance testified. Because Collins did not immediately object to the officer’s presence, the issue may only be reviewed for plain error. However, even under plain-error review, the district court was not required to order a mistrial upon Collins’s late mistrial motion. Instead, the trial court enjoys wide latitude to fashion the appropriate remedy for a violation, including a warning by the court prohibiting such contact, exclusion of testimony of the violating witness, or awarding a mistrial. We review that decision for an abuse of discretion.
Vallie,
E. Factual Impossibility
Collins next argues that he had “at least a partial factual impossibility defense” that the jury “disregarded” despite being specifically instructed that Collins was incarcerated during various periods within the time-frame in the indictment. Collins argues that when he was detained during these various dates, it was impossible for him to commit the crime of conspiracy. He also argues that although Matejka testified that the two of them completed at least thirty-five drug deals between July and October 2000, these deals could have only taken place during July and August *682 because Collins returned to custody in September of 2000. Collins offers no legal argument to support his claim.
Factual impossibility refers to those situations in which a circumstance or condition, unknown to the defendant, renders physically impossible the consummation of his intended criminal conduct. The oft-cited example is of the would-be thief who attempts to pick an empty pocket.
See United States v. Frazier,
F. Daubert Inquiry for Fingerprint Evidence
Collins next argues that the district court erred in failing to conduct a Daubert 5 analysis on fingerprint evidence used to enhance his sentence. The court admitted fingerprint evidence to identify Collins as the same person convicted of prior offenses. Collins challenged whether the fingerprints from his previous custody dates bore enough “indicia” of identity with Collins’s fingerprints to support a conclusion that Collins committed the prior crimes. Collins argues that the fingerprint analysis did not meet Daubert’s requirements for admission and use at sentencing to trigger the mandatory life sentence. Collins asserts that this was not harmless error, and his failure to challenge the admission of this evidence below does not prevent this court from declaring it as plain error.
We will apply a plain-error analysis because Collins failed to object to the admission of the fingerprint expert’s testimony at trial. “Without an objection and a proper request for relief, the matter is waived and will receive no consideration on appeal absent plain error.”
McKnight v. Johnson Controls, Inc.,
There is no plain error here. Fingerprint evidence and analysis is generally accepted.
See, e.g., United States v. Havvard,
G. Denial of Motion for Dovmward, Departure
In his final point on appeal, Collins argues that the district court erred in denying his motion for downward departure under United States Sentencing Guidelines § 5K2.0 and § 4A1.3. Collins asserts that the district court mistakenly believed that it did not have the power to depart due to the application of the career offender statute and 21 U.S.C. § 841 (1999), and that the district court indicated that Collins’s criminal history was “overstated.” Collins addresses various prior offenses used to calculate his criminal history and argues that these should have only placed him in Criminal History Category V instead of Category VI.
Because the government did not file a motion for a downward departure from the statutory mandatory minimum sentence, the district court properly determined that it had no authority to depart.
See
18 U.S.C. § 3553(e) (2000);
United States v. Johnson,
In this case, whether the mandatory life sentence under § 841 (b)(1) (A) (viii) applies depends on whether 500 or more grams of methamphetamine were involved in Collins’s offense.
See
21 U.S.C. § 841(b). The jury convicted Collins of conspiring to distribute and possess with intent to distribute 500 or more grams of methamphetamine, a fact the sentencing court was permitted to adopt because the same court presided over the trial in the case.
See Wiggins,
We affirm the district court.
Notes
. The Honorable Richard G. Kopf, Chief Judge, United States District Court for the District of Nebraska.
. Each of these witnesses engaged in drug transactions with Collins from March 1999 to September 15, 2001, as follows: in April 2001, Horan bought methamphetamine from Collins twice, for a total of one-eighth of an ounce, at Bart’s Motel in Council Bluffs, Iowa; between 1999 and 2001, Stewart bought methamphetamine from Collins on various occasions (once at Bart’s Motel), and during a six-month period in 2000, she bought one-fourth of an ounce to one ounce of methamphetamine about every other day; Erickson, a twenty-year acquaintance, testified that she first bought drugs from Collins within the first two years of meeting him, and that the last time she bought drugs from Collins was on the day he was arrested; Rydberg testified that he bought at least one-half of an ounce of methamphetamine on at least six occasions, and that Hald was the "middleman” in many of the transactions from July 2000 to January 2001; Hald, a fifteen-year acquaintance of Collins’s, testified that over one summer, he and Collins engaged in forty to fifty transactions in a two-month period for amounts ranging from one-sixteenth of an ounce to half pounds, with the weight of all transactions totaling at least three pounds, and that in March or April 2001, on six to eight occasions, Hald resold a total of one to two ounces of methamphetamine to others with Collins’s knowledge; Gomez testified that she bought methamphetamine from Collins eight to ten times in the spring of 2001 in amounts ranging from one-sixteenth of an ounce to one-quarter of an ounce, and that the largest amount she saw in Collins's possession was about one pound of methamphetamine on three or four occasions; Matejka testified that he first bought methamphetamine from Collins in 1999, that Collins paid him with one-sixteenth of an ounce of methamphetamine for helping friends move some furniture, and that until February 5, 2001, he and Collins engaged in up to eighty transactions of one gram to one ounce per transaction, for a total of over one-half of a pound of methamphetamine.
. Collins's prior felonies involved the delivery and manufacture of marijuana and a controlled substance.
. Daubert v. Merrell Dow Pharmaceuticals, Inc.,
509
U.S.
579,
. The Seventh Circuit stated in
Havvard,
The issue of the reliability of fingerprint evidence after Daubert appears to be one of first impression in this circuit, and few other courts have addressed this question. Those discussing the issue have not excluded fingerprint evidence; instead, they have declined to conduct a pretrial Daubert hearing on the admissibility of fingerprint evidence, or have issued brief opinions asserting that the reliability of fingerprint comparisons cannot be questioned.
