In a packed courtroom in Miami-Dade County yesterday, January 5, 2026, 15-year-old Derek Rosa was dressed in a plain brown jail jumpsuit, sitting quietly at the defense table. When prosecutors started playing the audio from his 911 call where he confessed to killing his mother, he clamped his hands over his ears and dropped his head down low, like he couldn’t bear to hear it again. That raw moment got caught on a short, silent video that’s been making the rounds on X, really driving home how heavy this pretrial hearing felt for everyone involved.
The whole point of the hearing was to hash out whether Rosa’s confession made right after the 2023 incident should even be admissible in his upcoming trial. His defense team is fighting hard to keep out both the 911 recording and a video of his police interrogation, saying that at just 13 years old back then, he couldn’t have fully grasped his Miranda rights or what waiving them meant. On the flip side, the prosecutors are insisting it’s fair game, pointing out that he called the cops himself almost immediately after.

This clip on X, posted by @unlimited_ls, runs about 61 seconds and shows Rosa’s distress pretty clearly he keeps covering his ears and looks totally shaken. It’s grainy, low-resolution footage shot on the down low from the public seats, with no audio whatsoever from the courtroom. You see glimpses of the judge’s bench and the lawyers, but nothing was said about what was said on that 911 call. Without audio or full context, stuff like this can very well make people jump to conclusions by filling in the blanks with assumptions about what Rosa was thinking or what the call revealed. That would be a good example of why solid, complete reporting-as opposed to just these viral scraps that blow up online-is so necessary.
Flash back to October 12, 2023, in a Hialeah apartment: prosecutors say Derek Rosa stabbed his mom, Irina Garcia over 40 times while she was asleep next to her newborn baby girl. The infant was in her crib, and wasn’t injured at all. Rosa – then 13-years-old – dialed 911 soon after telling the dispatcher he’d stabbed someone and providing the address straight away.
From court documents, we know he allegedly snapped some gruesome photos of the scene and sent them to an online buddy before taking off for a bit. Investigators dug up his search history about stabbings and saw he was into the “Friday the 13th” movies. The state claims he picked that timing right before the actual Friday the 13th to mimic Jason Voorhees, the slasher icon, but the defense is calling that a stretch and not relevant to why it happened.
In his interview with detectives, Rosa supposedly said he meant to kill his mom and then himself, but he left his little sister alone. Keep in mind, these are all just allegations from the filings nothing’s been proven in court yet.
Rosa’s entered a not guilty plea to first-degree murder and is being held without bail. His lawyers are pushing to toss the confession, arguing a kid that young couldn’t knowingly give up his rights without a parent or guardian there. They’re also trying to bar some autopsy photos, worried they’ll prejudice the jury too much.
The prosecution’s leaning on things like home security video and Rosa’s own words to show it was planned. Detective Joseph Elosegui gave testimony about the interrogation, according to reports from NBC Miami. This case touches on bigger issues in the U.S., like how we handle juveniles in adult court Florida’s pretty aggressive about it for serious violent crimes which sparks debates on brain development in teens and whether the system’s really just.
Trial’s set to kick off on January 26, 2026. Whatever Judge Richard Hersch decides on the evidence could swing things big time: if the confession gets suppressed, the state might have to build their case purely on physical stuff, which could poke holes in their premeditation angle and affect how jurors see guilt or what sentence to hand down. In Florida, a conviction here could mean life without parole, no questions asked.
