Following the appellant’s guilty plea to a federal drug-trafficking charge, the district court calculated the guideline sentencing range (GSR) to include as relevant conduct amounts of drugs and cash independently seized by local authorities in connection with an unrelated criminal investigation. This single-issue sentencing appeal challenges the court’s relevant conduct determination. We conclude that the appellant waived any objection to that determination and, in all events, the determination was not clearly erroneous. Accordingly, we affirm the sentence imposed below.
The facts are straightforward (although certain inferences therefrom are disputed). The venue is Portland, Maine. In June of 2007, the federal Drug Enforcement Administration (DEA) received a tip from a cooperating source (CS-1) that defendant-appellant Philjon Eisom was peddling crack cocaine. Under the DEA’s direction, CS-1 contacted the appellant on June 14 and purchased 6.5 grams of crack.
Two weeks later, a different informant (CS-2) effected another controlled buy, purchasing 10.8 grams of crack. In the course of this transaction, the appellant told CS-2 that he had more crack for sale and that he had made over $8,000 since setting up shop in Portland.
On July 6, the plot thickened: CS-2 informed DEA agents that he had agreed to buy two more ounces of crack from the appellant. The agents immediately arranged to surveil the site of the planned transaction (near the appellant’s home). While in place, they observed local law enforcement officers arrest the appellant as he left the apartment building in which he lived. A search of the appellant’s residence by the arresting officers, pursuant to a warrant issued by a state court, resulted in the seizure of 60 grams of powdered cocaine, 283.5 grams of crack cocaine, and $11,500 in cash.
As matters turned out, the local authorities had been investigating the appellant’s mercantile activities, independent of their federal counterparts. They proceeded to charge the appellant with two counts of unlawful trafficking in scheduled drugs and one count of aggravated trafficking. 1 Me.Rev.Stat. Ann. tit. 17-A, §§ 1103, 1105. The appellant pleaded guilty in the state court, but sentencing was delayed.
On September 18, 2007, a federal grand jury returned a one-count indictment charging the appellant with distributing, on June 28 of that year, five grams or more of cocaine base (crack cocaine) in violation of 21 U.S.C. § 841(a)(1). The *555 charge arose out of the appellant’s sale of 10.8 grams of crack to CS-2.
After some preliminary skirmishing, not material here, the appellant admitted his guilt with respect to the federal charge. The district court directed the probation department to prepare a presentence investigation report (PSI Report).
The PSI Report contained a recommendation that the activity underlying the state charges be considered relevant conduct, USSG § lB1.3(a)(2), in fixing the offense level for federal sentencing purposes. This encompassed the drugs that had been seized. In addition, noting that there was no indication of any legitimate source for the cash seized and that the cash had been found alongside the drugs, the probation officer included the cash in the recommendation, converting it into its crack cocaine equivalent for this purpose.
Id.
§ 2D1.1, cmt. (n.12);
United States v. Hall,
Next, the probation officer combined the drugs purveyed in the two controlled buys (17.3 grams of crack) and the contraband seized during the search of the appellant’s abode (283.5 grams of crack cocaine, a hypothetical 113.38 grams of crack resulting from the cash conversion, and 60 grams of cocaine powder) and attributed that total to the appellant. Because two different types of cocaine were involved, the probation officer followed the Guidelines Manual and used a common denominator, converting both types of cocaine into their marijuana equivalents. See USSG § 2D1.1, cmt. (n.lO(D)(i)). This yielded an aggregate quantity of 8,295.6 kilograms of marijuana and a base offense level of 32. See id. § 2331.1(c)(3); id. § 2D1.1, cmt. (n.l0(E)).
The probation officer then reduced the base offense level by three levels for acceptance of responsibility. Id. § 3E1.1. The appellant’s prior record placed him in criminal history category IV, 3 thus producing a GSR of 121-151 months. Id. ch. 5, pt. A (sentencing table).
The district court discussed the PSI Report and other sentencing issues with the prosecutor and defense counsel on June 11, 2008. The disposition hearing was held on July 10. Without objection, the court adopted the various calculations adumbrated in the PSI Report (including the relevant conduct recommendation); found the GSR to be 121-151 months; departed downward based on the appellant’s substantial assistance to the authorities, id. § 5K1.1; and imposed a 108-month prison term. This timely appeal followed.
The appellant is represented on appeal by newly appointed counsel. His brief makes a head-on challenge to the sentencing court’s relevant conduct determination. The government’s first line of defense is a claim that the appellant waived his right to *556 appeal that determination. We begin there.
The government’s claim requires us to distinguish between waiver and forfeiture. Waiver, on the one hand, is the intentional relinquishment of a known right.
United States v. Olano,
The consequences of trial-court-level waiver and forfeiture differ with respect to subsequent attempts to appeal. Typically, a waived claim is dead and buried; it cannot thereafter be resurrected on appeal.
See, e.g., United States v. Sumner,
In this case, the appellant and his counsel received the PSI Report well in advance of sentencing. They interposed a written objection to the portion of the report that recommended the inclusion, as relevant conduct, of the drugs and cash seized by local authorities. See D. Me. R. 132. At the June 11 sentencing conference, the lawyer advanced the same objection, stating that he wished to object both to the inclusion in the PSI Report of the “facts contained in Paragraphs 8 and 9,” which describe the drugs and cash seized by local authorities, and to “those facts being used to determine [the appellant’s] base offense level.” Plainly, then, the contours of the claim were known to the appellant and identified to the court by him prior to sentencing.
At the disposition hearing, defense counsel unambiguously withdrew this objection. The court sought to verify its understanding that the recommendations contained in the PSI Report (including the proposed relevant conduct determination) were no longer disputed. Defense counsel replied: “That’s correct.” The court then asked the appellant himself whether he approved of his attorney’s statement that the contents of the PSI Report were undisputed. The appellant said that he did.
We have stated that “[a] party who identifies an issue and then explicitly withdraws it, has waived the issue.”
Rodriguez,
So it is here. We hold that any objection to the inclusion of the seized drugs and cash as relevant conduct for purposes of setting the appellant’s offense level was waived and, consequently, cannot now be deployed as a basis for appeal.
We hasten to add that, even if preserved, the appellant’s claim of error would prove unavailing. We explain below.
*557
In order to go beyond the conduct involved in the offense of conviction and include other (uncharged) conduct in the calculation of a defendant’s offense level, that uncharged conduct must be relevant to the charged conduct. USSG § 1B1.3. Where, as here, the offense of conviction is “of a character for which [USSG] § 3D1.2(d) would require grouping of multiple counts,” uncharged conduct is relevant if the government proves by a preponderance of the evidence that such uncharged conduct is part of the same course of conduct or common scheme or plan as the charged conduct.
Id.; see United States v. Blanco,
A district court’s determination of the scope of a particular scheme, plan, or course of conduct “represents a practical, real-world assessment of probabilities, based on the totality of proven circumstances.”
United States v. Sklar,
The relevant conduct guideline can find fertile soil in drug-trafficking cases. Under that guideline, drug quantities not charged as part of the offense of conviction may be included in determining the defendant’s offense level as long as those uncharged quantities are support-ably found to be part of a common course of conduct, scheme, or plan that includes the offense of conviction. USSG § 1B1.3(a)(2);
see United States v. Bryant,
In the case at hand, these factors coalesce to support the district court’s relevant conduct determination. First, the charged and uncharged acts are of the same nature; crack cocaine, a drug of choice in both instances, was distributed on June 28 and was possessed in such a quantity on July 6 that the intent to distribute can readily be inferred.
Second, the compressed time frame during which the events transpired is telling. The controlled buy that forms the predicate for the federal indictment took place on June 28, 2007. That was within two weeks of when local authorities searched the appellant’s abode and seized the above-described contraband. This timing strongly supports a conclusion that all the drugs, and the cash, were part of the same course of conduct.
See, e.g., United States v. Santos Batista,
Third, on the very day that the search occurred, a cooperating source in the federal investigation was scheduled to purchase crack from the appellant. It is a logical (perhaps inevitable) inference that the two ounces of crack that CS-2 had arranged to buy were to come from the stash seized in the search.
*558
Fourth, during the controlled buy that constitutes the offense of conviction, the appellant told CS-2 that he had more crack for sale and that he had made $8,200 from peddling drugs in Portland. These statements are indicative of an ongoing operation. That indication is reinforced by two admissions. For one thing, the appellant made clear that he was keeping a running tally of his drug-trafficking profits.
Cf. Hall,
That ends this aspect of the matter. The similar nature of the crimes, their closeness in time, the appellant’s statements, and the other circumstances permit the common-sense inference that the seized contraband was part and parcel of the same illicit course of conduct as the offense of conviction.
In an effort to undermine this inference, the appellant argues that there was no direct evidence linking the seized contraband to the drugs sold to CS-2. That may be so-but a relevant conduct determination may be grounded in circumstantial evidence.
See Sklar,
The appellant also notes that the seized contraband was used to ground a separate state court prosecution. This fact, he insists, requires its exclusion in the federal sentencing calculus. We disagree.
An application note to the relevant conduct guideline is instructive. That note provides an example that is strikingly similar to the facts of this case: a hypothetical defendant engages in two cocaine sales, and is charged by state authorities for the first and by federal authorities for the second. The application note concludes that, under the relevant conduct guideline, the cocaine sale associated with the state charge can be considered relevant conduct vis-a-vis the federal charge as long as the two offenses arise out of a common scheme, plan, or course of conduct.
See
USSG § 1B1.3, cmt. (n.8). The case law is to the same effect.
See United States v. Maken,
We hold, therefore, that prosecution of conduct by a separate sovereign in a separate proceeding does not, without more, disqualify that conduct from inclusion in a federal court’s sentencing calculus pursuant to the relevant conduct guideline. 4
*559
The appellant makes other arguments, most of which are related in one way or another to his arguments discussed above. These other arguments are meritless, and we reject them out of hand. It suffices to say that the record supports a conclusion that the drugs sold during the offense of conviction and the drugs and cash seized were part of a single course of continuous drug-trafficking activity.
See, e.g., Sklar,
We need go no further. For the reasons elucidated above, we affirm the sentence imposed by the district court.
Affirmed.
Notes
. The state also sought forfeiture of the cash and other items, but the forfeiture count is immaterial here.
. Although the federal indictment charged only the June 28 sale to CS-2, the appellant does not question that the drugs involved in the June 14 sale to CS-1 are properly included as relevant conduct.
. No criminal history points were added to the appellant’s criminal history score for the pending state charges.
. We caution that a different rule might apply if a defendant had committed a state offense and served a state-imposed sentence for it prior to committing the (federal) offense of conviction.
See
USSG § 1B1.3, cmt. (n.8) ("For the purposes of subsection (a)(2), offense conduct associated with a sentence that was imposed prior to the acts or omissions constituting the instant federal offense (the offense of conviction) is not considered as part of the same course of conduct or common scheme or plan as the offense of conviction.”);
