The Sawyer County prosecution now includes two defendants. Xzavier Barreras was charged first in the June killing of 16-year-old Nolan Trotterchaude, and authorities later arrested Brennen Boswell on allegations that he participated in the planned armed robbery that ended in the teen’s death.
The Crime
The case began with the June 2026 shooting death of 16-year-old Nolan Trotterchaude in Sawyer County, Wisconsin. Investigators said the teenager met with older teens in connection with a planned firearm transaction. The prosecution’s theory, as described in the criminal complaint and local reporting, is that the meeting was instead used as an opportunity to rob him. The encounter ended with Trotterchaude fatally shot.
The early public case centered on Xzavier Barreras, 19, of Black River Falls. Authorities accused Barreras of shooting Trotterchaude during the attempted armed robbery. He was arrested and charged in July, bringing the homicide out of the investigative stage and into a criminal prosecution. The complaint-based reporting described a sequence in which the victim arrived expecting a gun transaction and the planned robbery escalated into deadly violence.
Charges Against Xzavier Barreras
Barreras was charged with felony murder while committing or attempting armed robbery. Reporting on the complaint also described counts involving negligent handling of a dangerous weapon. He was held on a reported $1 million cash bond after the initial charging. Those allegations remain accusations unless established by a guilty plea or verdict.
The felony-murder theory is significant because it focuses on a death occurring during another serious felony. Prosecutors do not have to reduce the case to a simple question of whether a robbery and a shooting happened at the exact same instant. Instead, the state alleges that the planned armed robbery created the criminal episode in which Trotterchaude was killed. The precise elements and any lesser or alternative counts will be determined by Wisconsin law and the court record.
Second Suspect Brennen Boswell Arrested
The case materially changed on August 4, 2026, when authorities announced the arrest of a second suspect, 18-year-old Brennen Boswell. Reporting on the arrest said Boswell was accused of being a party to felony murder during an armed robbery. That allegation moves the prosecution beyond the earlier single-defendant headline and is why the article now names both Barreras and Boswell.
Being charged as a party to a crime does not necessarily mean prosecutors claim two people performed the same physical act. Wisconsin law can allow criminal liability for someone who directly commits an offense or intentionally aids and abets it, depending on the charged theory and proof. The public reports say prosecutors accuse Barreras of firing the fatal shot while alleging Boswell participated in the planned robbery. Those roles should not be blurred into an unsupported claim that both men fired at the victim.
What Investigators Say Happened
Complaint-based reporting said the meeting involved a plan to take a firearm from Trotterchaude. Investigators pieced together the circumstances using witness information, statements and other evidence described in the charging materials. The prosecution alleges that what appeared to the victim to be a transaction became an attempted robbery and that the confrontation led to gunfire.
The distinction between the allegation and a proven fact remains important. Criminal complaints present the evidence prosecutors believe establishes probable cause. They are not trial verdicts. Defense attorneys can challenge witness accounts, the interpretation of messages or planning evidence, who possessed particular weapons, intent, causation and whether the state can prove each defendant’s alleged participation beyond a reasonable doubt.
Victim and Community Impact
Trotterchaude was 16 years old. Public reporting identified him as a teenager from the Lac Courte Oreilles area. His death turned what prosecutors describe as a planned property crime into a homicide case with lasting consequences for his family and community. The article avoids unnecessary private details about the victim while preserving the facts needed to understand the prosecution.
The age difference also matters to the public record. Barreras was 19 when charged and Boswell was 18 when the second arrest was announced. Trotterchaude was a minor. Those ages do not decide criminal responsibility, but they help explain why the case drew substantial local attention and why the second arrest was a meaningful update rather than a routine docket event.
Current Case Status
As of August 11, 2026, the reviewed public sources describe Barreras and Boswell as defendants in the same Sawyer County homicide prosecution. Barreras faced felony-murder and related allegations, and Boswell was later accused as a party to felony murder during the alleged armed robbery. No completed guilty plea, trial verdict, dismissal or sentence for either defendant was located in the reviewed sources.
The August 4 arrest is the latest completed substantive development verified for this article. Any scheduled preliminary hearing, arraignment, motion hearing or trial date is not treated as an outcome until it occurs and the result can be verified. Future changes in charges, bond, plea posture or disposition should be folded into this article rather than published as another competing version of the same case.
Why This Article Was Updated
The earlier headline named only Barreras because he was the only charged defendant then publicly identified. Once Boswell was arrested and accused of participating in the same robbery-homicide, leaving the old title and status untouched would have made the page materially stale. The update keeps the original case together while preserving the different allegations against each defendant.
That approach also avoids overstating the evidence. The prosecution alleges that Barreras fired the fatal shot and that Boswell participated in the underlying armed-robbery plan. The current record does not justify describing the two men as having identical conduct. Both remain presumed innocent unless and until guilt is established in court.
What to Watch Next
The next meaningful update will be a completed court event that changes the defendants’ legal posture, such as an amended complaint, bond decision, plea, dismissal, trial ruling or sentence. Because two defendants are now tied to the same alleged robbery-homicide, their cases may move on different schedules and may not produce identical outcomes. Future coverage should identify which defendant a ruling applies to and should not treat an allegation against one as automatically established against the other. The canonical page should also preserve the distinction between the alleged shooter and alleged accomplice unless later court findings change that description.
