United States Court of Appeals For the First Circuit

No. 24-1583

UNITED STATES OF AMERICA,

Appellee,

v.

ADAM JOHNSON,

Defendant, Appellant.

APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF MAINE

[Hon. Lance E. Walker, U.S. District Judge]

Before

Montecalvo, Kayatta, and Rikelman, Circuit Judges.

Ronald W. Bourget for appellant. Brian S. Kleinbord, Assistant U.S. Attorney, with whom Craig M. Wolff, Acting U.S. Attorney, was on brief, for appellee.

May 28, 2026 KAYATTA, Circuit Judge. A jury convicted Adam Johnson

of conspiracy to distribute and to possess with intent to

distribute 400 grams or more of fentanyl in violation of 21 U.S.C.

§§ 846, 841(a)(1), and 841(b)(1)(A). On appeal, Johnson contends

that the proceedings below were tainted by the court's failure to

hold an evidentiary hearing before denying his motions to exclude

his plea and cooperation agreements as well as his grand jury

testimony. Johnson also challenges his sentence, asserting that

the court erred in enhancing his offense level based on testimony

of a deceased witness and in refusing to grant him credit for

acceptance of responsibility despite his prior cooperation.

Finding Johnson's arguments either unpreserved or

lacking merit, we affirm the verdict and sentence. Our reasoning

follows.

I.

This case presents an unusual procedural history

spanning over half a decade, five different defense attorneys, and

two district court dockets.

On February 21, 2018, New Hampshire State Police stopped

Johnson for a defective taillight and found fifty-three grams of

heroin on his person. Johnson confessed to purchasing drugs and

provided information regarding several distributors, after which

he was extradited to Maine on a warrant for a failure to appear in

a separate matter. Upon his return to Maine, Johnson enrolled as

- 2 - a confidential source (CS) for the Drug Enforcement Agency (DEA).

He entered into two agreements with the DEA, beginning on May 31,

2018. 1 The DEA anticipated that, in exchange for his

cooperation -- which included providing real-time information to

agents and disclosing information about his suppliers -- Johnson

would not be charged with possessing heroin at the time of his

February arrest.

But Johnson's work as a CS did not itself entitle him to

immunity from any and all criminal charges. Around January 3,

2019, the government served Johnson with a target letter stating

that they had received "substantial evidence relating to [his]

violation of federal narcotics trafficking laws." Johnson

received his first appointed counsel at that point. Although he

had been terminated as a CS for the DEA, Johnson continued to

cooperate with the government through proffers to government

agents on March 27, 2019, and again on October 29, 2019.2 In the

1 The first agreement pertained to work as a CS from May 31, 2018, through September 1, 2018. The second agreement pertained to work as a CS from September 1, 2018, through December 1, 2018. The DEA deactivated Johnson as a CS on November 29, 2018, due to his incarceration. 2 Johnson signed a "proffer" agreement on March 27, 2019, which provided that "[i]n any prosecution brought" against him, "the Government will not offer in evidence in its case-in- chief . . . any statements made by [Johnson] at the meeting, except in a prosecution for false statements, obstruction of justice or perjury with respect to any acts committed or statements made during or after the meeting or testimony given after the meeting."

- 3 - intervening months, Johnson's first counsel withdrew due to a

conflict of interest. During the October proffer, the government

provided to Johnson and his new appointed counsel an overview of

the proposed plea and cooperation agreements. At some point,

Johnson agreed to testify before a grand jury to assist the

government in its prosecution of other drug distributors.

On December 11, 2019, minutes prior to testifying before

the grand jury, Johnson signed the cooperation and plea agreements.

The plea agreement contained a provision stating that, in the event

of a breach by Johnson, "[t]he United States may use any statement

that [Johnson] made pursuant to this Agreement, including

statements made during plea discussions and plea colloquies, and

the fact that [Johnson] pleaded guilty." Additionally, Johnson

agreed to "waive[] any claim under Rule 410 of the Federal Rules

of Evidence or Rule 11(f) of the Federal Rules of Criminal

Procedure that such statements and guilty plea are inadmissible"

in the event of such breach.

The cooperation agreement also contained a provision

titled "Consequences of Breach," which provided that, if Johnson

"violates or fails to perform any obligations under this Agreement

or under the plea agreement ('a breach'), the United States will

be released from its obligations hereunder and may fully prosecute

[Johnson]." As most relevant to this appeal, under Section A of

the breach provision, Johnson agreed that the government could

- 4 - "use any statement that [he] made pursuant to [the] Agreement,

including statements made during proffers, debriefings, [and]

grand jury sessions" in the event of breach. He further "waive[d]

any claim under Rule 410 of the Federal Rules of Evidence or

Rule 11(f) of the Federal Rules of Criminal Procedure that such

statements and guilty plea are inadmissible."

When Johnson signed the final written agreements just

before testifying to the grand jury, his appointed counsel was not

present. Rather, he was represented by "fill-in" counsel arranged

by his attorney. There is no claim, however, that either written

agreement differed in relevant substance from what was discussed

at the October meeting between Johnson, his appointed counsel, and

the government. In his testimony before the grand jury, Johnson

confirmed both that he had had enough time to discuss the

agreements with the substitute attorney and that he was comfortable

proceeding with the substitute attorney. Johnson further admitted

to distributing fentanyl and heroin to support his addiction, and

he named his supplier and other distributors. When asked if he

hoped to receive a lower sentence for his cooperation, Johnson

responded, "Yes."

The following month, on January 29, 2020, the government

filed an information charging Johnson with conspiracy to

distribute and to possess with intent to distribute 400 grams or

more of fentanyl in violation of 21 U.S.C. §§ 846, 841(a)(1), and

- 5 - 841(b)(1)(A). Johnson was first scheduled to plead guilty to this

information on February 12, 2020 -- the same date of his

arraignment on the information and his waiver of indictment. That

hearing was initially rescheduled for unknown reasons to

February 28 and then to March 25, 2020. On March 19, 2020, the

court again rescheduled Johnson's hearing to May 13, 2020, in
