* Of the United States Court of Appeals for the Seventh Circuit, sitting by designation. April 15, 2026

- 2 - HAMILTON, Circuit Judge. Four police officers

brutalized a teenage boy during and after an arrest. Then they

covered it up. Federal prosecutors brought civil rights and

obstruction charges, securing guilty pleas from three officers. A

jury convicted the fourth, Defendant José Cartagena, on all counts.

At trial, however, the Government introduced into evidence a

hearsay statement from the victim, who was never available to the

defense for cross-examination, contrary to the defendant's rights

under the Confrontation Clause of the Sixth Amendment. We vacate

his conviction on the one count for which that statement was

important to the Government's case. We affirm the other

convictions as supported by sufficient evidence and remand for

further proceedings consistent with this opinion.

I. FACTUAL AND PROCEDURAL BACKGROUND

We relate the facts in the light most favorable to the

verdicts. United States v. Buoi, 84 F.4th 31, 34 (1st Cir. 2023).

Because there are as many variations on the story as there were

people telling it, if not more, we try to avoid extraneous details.

In November 2014, Defendant Cartegena was an officer in

a police drug unit. He was on patrol in Canóvanas, Puerto Rico,

with fellow officers in the Carolina precinct's drug unit, Jimmy

Davis, Carlos Nieves, and Shylene Lopez. The officers encountered

two young men on the side of the road. Suspicious that a drug

deal was occurring, the officers tried to confront them. The

- 3 - youths fled, one on foot and the other, 17-year-old Calep Carvajal,

on a bicycle. Nieves shot Carvajal in the back. Cartagena gave

chase on foot, caught up to Carvajal, tackled him to the ground,

and handcuffed him. Count 1 of the indictment charged that

Cartagena violated 18 U.S.C. § 242 in the arrest by using unlawful

force in violation of the Fourth Amendment by pistol-whipping

Carvajal in the back of the head while he lay on the ground,

unarmed and not resisting.

The assaults continued as the officers put Carvajal in

the squad car, with his hands cuffed behind his back, to take him

to a police station. When Carvajal leaned forward to avoid "smacks

and hits" coming from Lopez and Nieves, who were seated beside

him, Cartagena turned around from the front passenger seat and, as

charged in Count 2 of the indictment, also under § 242, twice

struck Carvajal hard in the face.

After arriving at the station, Davis and Lopez took

Carvajal into an office where he was beaten some more. Meanwhile,

Cartagena and Nieves discussed how to cover up what they had done.

Each wanted the other to take responsibility for handling the

administrative side of the case. In the end, Cartagena wrote the

use-of-force report. As charged in Count 6 of the indictment under

18 U.S.C. § 1519, he falsified that report by intentionally

omitting that Carvajal had been shot, pistol-whipped, and

repeatedly punched. He wrote instead that the officers had given

- 4 - "verbal warnings." In the narrative section, Cartagena explained

Carvajal's injuries as having been caused by losing control of his

bicycle and falling to the ground.

Carvajal was charged with and later pled guilty to drug

possession in a Commonwealth court for a small bag of drugs found

near him. As charged in Count 7 of the indictment, 18 U.S.C.

§ 1512(b)(3), Cartagena obstructed justice by intentionally lying

to the juvenile prosecutor that Carvajal might falsely claim during

those proceedings that the officers assaulted him, even though his

injuries, Cartagena falsely assured the prosecutor, were

"exclusively" from falling off the bicycle.

Around a year later, Cartagena reached out to the Federal

Bureau of Investigation to report misconduct committed by his

colleagues in the Carolina drug unit, including the incident

involving Carvajal. Cartagena was not the first to report the

Carvajal incident and its cover-up to the FBI. The FBI had

apparently already located Carvajal and had him undergo a medical

examination in which he told a doctor that he had been shot and

that his head wound was caused by a blow from a pistol. Across a

series of four interviews, Cartagena told Agents Brian Doyle and

Ronnie Bobbitt that Nieves had shot Carvajal without

justification, that he himself had hit Carvajal in the back of the

head with his gun when the teenager tried to stand up as Cartagena

arrested him, that Davis struck Carvajal as he tried to apologize

- 5 - for fleeing just before being put in the car, and that he himself

had struck Carvajal in the face in the car when he leaned forward

to avoid blows from Lopez and Nieves.

In August 2016, a grand jury in the District of Puerto

Rico returned a seven-count indictment against Cartagena, Nieves,

Davis, and Lopez. Cartagena faced Counts 1, 2, 6, and 7 as set

forth above, while Nieves, Davis, and Lopez faced Counts 3, 4, and

5, respectively, each under § 242, for their assaults. The other

three defendants reached plea agreements. Cartagena also reached

a plea agreement but was later allowed to withdraw his plea. He

was convicted on all counts and sentenced to concurrent terms of

84 months in prison on each count. He appeals his convictions.

II. SUFFICIENCY OF THE EVIDENCE

Cartagena first challenges the sufficiency of the

evidence against him. Although he moved for a judgment of

acquittal at the close of the Government's case under Federal Rule

of Criminal Procedure 29(a), he failed to renew that motion after

the verdicts under Rule 29(c). Our review is therefore strictly

limited. Under these circumstances, we "may not intercede except

to prevent a clear or gross injustice." United States v.

Hernández-Román, 981 F.3d 138, 143 (1st Cir. 2020). No such

injustice exists if the evidence, viewed in the light most

favorable to the verdicts, is sufficient to support the

convictions. Id.; United States v. Van Horn, 277 F.3d 48, 54 (1st

- 6 - Cir. 2002). The Government asserts that Cartagena has not just

forfeited his sufficiency challenge but in fact waived it by
