Merger After Completed Fraud
Sofia Stern and Seth Shapiro agreed to submit false invoices to Summit Bank. Once Seth alone executed the scheme and the bank paid the claims, Sofia faced charges only for the completed fraud. The agreement merged into the substantive offense, barring a separate conspiracy conviction.
Parking Lot Surveillance Falls Short
Samantha Stone drove to Sentinel Security's headquarters with stolen credentials and a laptop. She circled the lot searching for an entry point but never left her car or connected to the network. Officers arrested her before she approached any building, so her conduct never reached the substantive theft offense under the proximity test.
Spencer Silver prepared and submitted a forged medical claim to Southland Foods' insurer using what he believed was an active policy number. The policy had been canceled months earlier, an unknown fact that blocked any payout. Because the believed facts would have completed insurance fraud, factual impossibility supplied no defense to attempt.
Missing Materiality Bars Attempt
Sydney Santos prepared a false affidavit she intended to use in litigation. Even if filed exactly as planned, the statement lacked the materiality element required for perjury. Because the completed conduct would not have constituted the substantive offense, legal impossibility defeated the attempt charge.
Merger Bars Separate Conspiracy
Sylvia Santos and Samantha Stone conspired to embezzle funds from Sapphire Holdings. Each later performed distinct withdrawals that constituted completed thefts. The completed substantive offenses absorbed the conspiracy under the merger rule, precluding a separate conspiracy conviction on the same agreement.
Pinkerton v. United States328 U.S. 640, 66 S.Ct. 1180, 90 L.Ed. 1489
Walter and Daniel Pinkerton are brothers who lived a short distance from each other on Daniel's farm. They were indicted for violations of the Internal Revenue Code. The indictment contained ten substantive counts and one conspiracy count.
The jury found Walter guilty on nine of the substantive counts and on the conspiracy count. It found Daniel guilty on six of the substantive counts and on the conspiracy count. Walter was fined $500 and sentenced generally on the substantive counts to imprisonment for thirty months. On the conspiracy count he was given a two year sentence to run concurrently with the other sentence. Daniel was fined $1,000 and sentenced generally on the substantive counts to imprisonment for thirty months. On the conspiracy count he was fined $500 and given a two year sentence to run concurrently with the other sentence.
The judgments of conviction were affirmed by the Circuit Court of Appeals. The Supreme Court granted certiorari because one of the questions presented involved a conflict between the decision below and United States v. Sall, decided by the Circuit Court of Appeals for the Third Circuit.
A single conspiracy was charged and proved. Some of the overt acts charged in the conspiracy count were the same acts charged in the substantive counts. Each of the substantive offenses found was committed pursuant to the conspiracy. There is no evidence to show that Daniel participated directly in the commission of the substantive offenses on which his conviction has been sustained. There was evidence to show that these substantive offenses were in fact committed by Walter in furtherance of the unlawful agreement or conspiracy existing between the brothers. Daniel in fact was in the penitentiary, under sentence for other crimes, when some of Walter’s crimes were done. The indictment was filed after a prior one for conspiracy alone had been dismissed following reversal on appeal.
Seth Shapiro was convicted of the completed bank fraud after a jury found the elements of the substantive offense. The underlying agreement could not support an additional conspiracy conviction once the substantive crime was finished. The substantive crime conviction stood alone under the merger doctrine.
United States v. Booker543 U.S. 220 (2005)
Respondent Freddie Booker was charged with possession with intent to distribute at least 50 grams of crack cocaine in violation of 21 U.S.C. § 841(a)(1). The jury heard evidence that he possessed 92.5 grams in his duffel bag and found him guilty. Based on the jury's findings and his criminal history, the Guidelines called for a base sentence of 210 to 262 months.
At sentencing, the district judge found by a preponderance that Booker possessed an additional 566 grams of crack and had obstructed justice. These findings raised the range to 360 months to life. The judge imposed 360 months.
In the companion case, respondent Ducan Fanfan was convicted of conspiracy involving at least 500 grams of cocaine. The jury verdict authorized up to 78 months. The judge found additional facts that would have raised the range to 188 to 235 months but declined to apply them after Blakely.
The Seventh Circuit held Booker's sentence violated the Sixth Amendment under Blakely and Apprendi. It remanded for resentencing based on jury findings. The Government sought certiorari in both cases, which the Court granted.
When does a conspiracy merge into the substantive crime at common law?
Merger occurs once the conspirators complete the substantive offense that was the object of their agreement. The participants may be convicted of the completed crime, but the law does not permit a separate conviction for the conspiracy based on the same agreement and completed offense.

Does factual impossibility ever bar attempt liability for a substantive offense?
No. A defendant may not invoke factual impossibility as a defense when an unknown physical or factual condition prevented completion of the substantive offense. Liability attaches if the conduct would have constituted the completed crime had the facts been as the defendant believed them to be.

What distinguishes legal impossibility from factual impossibility in attempt cases?
Legal impossibility is a complete defense because the intended conduct would not constitute a crime even if carried out exactly as planned. Factual impossibility supplies no defense because the only barrier is an unknown factual condition that would not have altered the criminal character of the acts.

How close must conduct come to the substantive offense under the common law proximity test?
The defendant's acts must come so near to accomplishment that the substantive crime would have been committed but for an interruption. Traveling to the general area or other preparatory steps that leave substantial acts undone fall short of attempt liability.

…of guilt, the court determined, and did not appear " tailored to permit the . . . finding to be a tail which wags the dog of the substantive offense.' " 304 N. J.
