Kim Darby Saenz pled guilty to one count of conspiracy to distribute marijuana. At sentencing, the government moved, pursuant to USSG § 5K1.1 and 18 U.S.C. § 3553(e), to reduce her sentence below the applicable sentencing guideline range of 63 to 78 months and the statutory minimum sentence of 60 months. The district court granted the motion and sentenced Saenz to 20 months’ imprisonment. The government appeals the extent of the reduction in sentence, and we reverse.
I.
Pursuant to a plea agreement with the government, Saenz pled guilty to one count of conspiracy to distribute marijuana. Saenz was charged after officers discovered marijuana in two vans located in a parking lot of a hotel in Onawa, Iowa. Saenz and her husband, Rudolph, were staying in a hotel room directly in front of the vans, and officers confronted them after finding the marijuana. After the Saenzes admitted to traveling in one of the vans, they were placed under arrest. A man and woman, Veronica Rodriguez-Cortez and Jose Rodriguez-Medrano, were staying in the room next to the Saenzes, and they were also arrested. When the *1161 foursome was interviewed, law enforcement officers learned that a third vehicle was traveling with the group. Officers located this vehicle, and a passenger, Christian Jimenez of San Diego, eventually was charged together with Rodriguez-Me-drano.
Rodriguez-Cortez later testified before the grand jury that Rodriguez-Medrano had approached her and asked that she transport two vans filled with marijuana from Chula Vista, California, to Sioux City, Iowa. Rodriguez-Cortez said that she told Saenz about the trip, and Saenz and her husband drove the second van. Rodriguez-Medrano urged them to bring their children, in order to disguise the purpose of their travel, and agreed to pay each of them $2500 for making the trip. Rodriguez-Medrano, Rodriguez-Cortez, Rudolph Saenz, and Jimenez eventually all pled guilty to drug trafficking offenses.
A presentence investigation report recommended a sentencing range of 63 to 78 months’ imprisonment for Ms. Saenz under the then-mandatory United States Sentencing Guidelines. At sentencing, the government moved to reduce the sentence under USSG § 5K1.1 and 18 U.S.C. § 3553(e), based on Saenz’s provision of substantial assistance, and recommended a departure of 30 percent, or 19 months, to a final sentence of 44 months’ imprisonment.
In support of its substantial-assistance motion, the government described Saenz’s cooperation. According to the government, Saenz talked to law enforcement officers about her co-conspirators on the same day that she was arrested. Within a day or two, the information provided by Saenz was used, along with statements obtained from the co-conspirators, to assist in the preparation of affidavits in support of criminal complaints. Saenz later testified at the sentencing hearing for Rodriguez-Medrano, where she corroborated testimony of Rodriguez-Cortez regarding the use of minors to avoid detection. Saenz also attempted to cooperate with Drug Enforcement Administration agents in San Diego while she was on pre-trial release, and assisted with the procurement of one search warrant, but the information that she provided was outdated and did not lead to any arrests or seizures.
The court granted the government’s substantial-assistance motions. In the court’s view, Saenz was “exceptionally timely” in her cooperation and there was “no indication that she was anything but totally truthful, complete, and reliable and that she gave them all the information she could.” (S. Tr. at 16). The court also opined that the government’s percentage recommendations for departures were “arbitrary and capricious and without any basis because they fail to disclose how they arrive at their decision.” (S. Tr. at 17). The court expressed its view that “any defendant who is timely, completely truthful, complete, reliable, and tells the government everything they need to know deserves more than 50 percent” reduction. (I'd). Citing its evaluation of the factors set forth in USSG § 5K1.1, the court reduced Saenz’s sentence to 20 months’ imprisonment.
II.
We recently reviewed three cases involving the reductions of sentences based on the provision of substantial assistance, and we set forth certain parameters regarding appellate review of such sentences.
See United States v. Dalton,
We said in
Dalton
that “[a]n extraordinary reduction must be supported by extraordinary circumstances,”
id.
at 1033, and we find that maxim applicable here. Departures under § 5K1.1 and reductions under § 3553(e) should not be untethered from the structure of the advisory guidelines. They take place, rather, within the framework of an advisory guideline scheme designed to reduce unwarranted sentence disparities among similar defendants,
see
18 U.S.C. 3553(a)(6);
United States v. Booker,
The extent of a departure or reduction pursuant to § 5K1.1 or § 3553(e) “can be based only on assistance-related considerations,”
United States v. Pepper,
(1) the court’s evaluation of the significance and usefulness of the defendant’s assistance, taking into consideration the government’s evaluation of the assistance rendered;
(2) the truthfulness, completeness, and reliability of any information or testimony provided by the defendant;
(3) the nature and extent of the defendant’s assistance;
(4) any injury suffered, or any danger or risk of injury to the defendant or his family resulting from his assistance;
(5) the timeliness of the defendant’s assistance.
USSG § 5Kl.l(a).
We are troubled in this case by the district court’s statement that “any defendant who is timely, completely truthful, complete, reliable, and tells the government everything they need to know deserves more than 50 percent” in reduction of sentence from the applicable guideline range.' Timeliness and truthfulness are
*1163
indeed two of the relevant factors for consideration, but we respectfully disagree with the district court’s apparent view that a strong showing in those areas makes reasonable an extraordinary departure or reduction of more than 50 percent, or the equivalent of more than about eight offense levels for this defendant, without regard to the nature and extent of the defendant’s assistance, the significance and usefulness of the assistance, or any danger or risk of injury suffered by the cooperating defendant. As we said in
Haack,
“[a] departure of this extent leaves little room for greater departures for defendants who actually participate in controlled buys, wear wires, give grand jury and trial testimony, or are subjected to significant risk of injury or death to themselves or their family.”
A review of the record in this case shows that while Saenz’s assistance is reasonably viewed as “substantial,” the nature and extent of her assistance was relatively limited, the significance and usefulness of her assistance is relatively modest, and she suffered no apparent danger or risk of injury. Saenz was one of four persons apprehended at the Onawa motel whose interview led to the arrest of Christian Jimenez. She testified as a corroborating witness at the sentencing hearing of Rodriguez-Medrano and provided evidence that supported a two-level adjustment in his guideline offense level.
See
USSG § 3B1.4. She tried unsuccessfully to assist with an investigation of drug trafficking in California. She did not, however, play a lead role in building a case on another offender, participate in undercover work (such as by wearing a recording device or making controlled purchases), give testimony in a grand jury or at a trial, or experience significant risk of injury or death.
See Haack,
We recognize that sometimes a defendant’s early cooperation will be so effective that another person will feel compelled to plead guilty on that basis, thus obviating the need for the cooperating defendant to provide testimony or perform other acts of assistance in that matter, and a district court may take account of such circumstances in evaluating the factors under § 5K1.1. Here, however, Saenz was not a key witness who helped bring to justice a major criminal figure. She was a corroborating witness and one of four conspirators who helped to identify a fifth. Of course, as the district court observed, “[t]he fact that she doesn’t know the whereabouts of Osama bin Laden is not her fault,” but the proper analysis under § 5Kl.l(a)(l) focuses on the actual significance and usefulness of the assistance, regardless of the defendant’s desire, effort,
*1164
or “fault.”
United States v. Davila,
The government stresses, in asserting unreasonableness, that the district court’s reduction in this case greatly exceeded that recommended by the United States Attorney, but we are not convinced by that point of argument. It is true, of course, that the district court must give “Substantial weight” to the government’s
“evaluation
of the extent of the defendant assistance, particularly where the extent and value of the assistance are difficult to ascertain.” USSG § 5K1.1, comment, (n. 3) (emphasis added);
Pizano,
We are less persuaded that the court must give substantial weight to the government’s
valuation
of the assistance, particularly where the government does not adequately explain its reasoning.
Haack,
403 at 1005 n. 2;
cf. Pizano,
Our decision in this case, therefore, turns not on the degree to which the district court’s decision varies from the government’s recommended reduction, but rather on our independent conclusion that the degree of reduction is not reasonable in light of the- evidence concerning the defendant’s assistance, the factors set forth in § 5K1.1, and the overall structure and theory of the guidelines, including the statutory command to reduce unwarranted sentence disparities. The appropriate degree of sentencing reduction cannot be calculated with “mathematical precision,”
