Defendant, Appellant.

APPEALS FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF PUERTO RICO

[Hon. Raúl M. Arias-Marxuach, U.S. District Judge]

Before

Gelpí, Montecalvo, and Rikelman, Circuit Judges.

Raúl S. Mariani Franco on brief for appellant. W. Stephen Muldrow, United States Attorney, Mariana E. Bauzá-Almonte, Assistant United States Attorney, and Julia M. Meconiates, Assistant United States Attorney, on brief for appellee.

February 23, 2024 GELPÍ, Circuit Judge. Defendant Juan Sierra-Jiménez

("Sierra") pled guilty to being a felon in possession of a firearm,

in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). The district

court sentenced him to fifty-eight-months' imprisonment, as well

as to a consecutive eighteen-month sentence for his related

supervised release violations. In this consolidated sentencing

appeal, Sierra challenges the procedural reasonableness of his

fifty-eight-month sentence and asserts that the government

breached the plea agreement with respect to his eighteen-month

sentence. Having discerned no error, we affirm.

I. BACKGROUND

We briefly begin with a review of the relevant facts

leading to the indictment for the new criminal conduct. Because

this appeal follows a guilty plea, we draw the facts from the plea

agreement, the presentence investigation report ("PSR"), the

change-of-plea colloquy, and the sentencing transcript. See

United States v. Spinks, 63 F.4th 95, 97 (1st Cir. 2023) (quoting

United States v. Ubiles-Rosario, 867 F.3d 277, 280 n.2 (1st Cir.

2017)).

While on supervised released for an earlier federal

firearm offense, Sierra failed to meet with his probation officer

to whom he also lied about where he had been. As a result, on or

about March 22, 2021, the probation officer sought and obtained an

arrest warrant. Upon his arrest, Sierra was found with a Glock 22

- 2 - pistol, modified to fire automatically as a machine gun. Agents

found the gun loaded with thirteen rounds in a magazine and one

round in the chamber, an additional loaded twenty-two-round

magazine containing twenty rounds, and approximately five grams of

what appeared to be heroin. Sierra was transported to a detention

center for processing and admitted thereat that the gun and other

items belonged to him. He was subsequentially indicted for

possessing a machine gun and being a felon in possession of a

firearm. 18 U.S.C. §§ 922(g)(1), 922(o), 924(a)(2). Sierra pled

guilty to the latter count by way of plea agreement.

The plea agreement proposed an advisory guideline range

calculation consisting of a base offense level of twenty for the

firearm count, see U.S.S.G. § 2K2.1(a)(4), and a three-level

reduction for acceptance of responsibility, see U.S.S.G.

§§ 3E1.1(a)-(b), for a total offense level of seventeen, which in

turn provides a sentencing range of thirty-seven to forty-six

months, taking into account his criminal history. Both parties

agreed to recommend a sentence at the lower end of the advisory

guideline range. As for the supervised release violation, the

parties agreed to recommend a concurrent sentence. The plea

agreement contained a stipulation of facts which provided that

during his arrest, Sierra was found with a gun, modified to shoot

automatically, loaded with thirteen rounds and an additional round

- 3 - in the chamber, as well as a twenty-two-round magazine containing

twenty rounds. No mention of the purported heroin seized was made.

The Probation Office next filed a PSR with a different

advisory guideline calculation. Because Sierra's possession of

the firearm in question followed two prior felonies, the base

offense level was twenty-six, as per U.S.S.G.

§ 2K2.1(a)(1)(A)(ii)(B). For his acceptance of responsibility,

three levels were reduced. U.S.S.G. § 3E1.1(a). Sierra's two

prior convictions and supervision status yielded a criminal

history category of IV, which juxtaposed with the total offense

level, resulted in a guideline sentencing range of seventy to

eighty-seven months. The PSR was more detailed than the plea

agreement's stipulation of facts, specifically noting the

suspected heroin that was also found during Sierra's arrest. In

his sentencing memorandum and during sentencing, Sierra objected

to the higher guideline calculation and mention of the suspected

heroin.

The sentencing and revocation of supervised release

hearings took place back-to-back on October 18, 2021. At

sentencing, the district court denied Sierra's objections to the

PSR. The district court found encouraging Sierra's expressions

during allocution that he strived to be a better father to his

children and correct his life's trajectory. However, it rejected

the parties' joint sentence recommendation given that this was

- 4 - Sierra's third machine gun offense.1 The district court noted that

it would normally be inclined to accept sentences jointly

recommended by the parties, but here could not "in good conscience"

do so. While it adopted the PSR's guideline calculations, the

district court nonetheless varied downward from the applicable

sentencing range.

In balancing the 18 U.S.C. § 3553(a) factors, the

district court discussed Sierra's personal history, his two

previous federal convictions for machine gun possession, and his

role in the offense. The district court also listed the items

found during Sierra's arrest, which included a modified and loaded

gun, extra rounds of ammunition, and about five grams of

"purported" heroin. Ultimately, the district court sentenced

Sierra to fifty-eight-months' imprisonment.

After pronouncing sentence for the new criminal conduct,

the district court proceeded to the revocation hearing. Sierra

requested an eighteen-month concurrent sentence while the

government made no specific recommendation.2 The district court

then imposed the eighteen-month sentence, however choosing that it

run consecutively to the fifty-eight-month sentence. The district

Sierra has two prior convictions for illegal possession of 1

a machine gun and one prior supervised release violation. The district court inquired whether the government would 2

like to make a statement, to which it responded, "No."

- 5 - court supported this outcome by noting that Sierra violated the

conditions of supervised release by engaging in new criminal

conduct and failing to follow the probation officer's

instructions, classified as Grade A and Grade C violations,

respectively, under U.S.S.G. § 7B1.1. The district court further
