Derek Rosa, 15, Faces Murder Trial Amid Protests: Supporters Claim Florida Teen Killer Deserves Leniency

Hialeah, Florida — As 15-year-old Derek Rosa prepared to stand trial for the brutal 2023 stabbing death of his mother, protests and public debate intensified outside the Miami-Dade County courthouse, with supporters arguing that the teen—diagnosed with mental health and neurological issues—deserves leniency rather than the maximum punishment.

Rosa, who was just 13 when he allegedly stabbed his 39-year-old mother Irina Garcia more than 46 times while she slept in their Hialeah apartment on October 12, 2023, was scheduled to face first-degree murder charges in a trial that had been pushed back to January 2026. Prosecutors alleged the horror fan, who took a bloody selfie with his mother’s body, was fascinated with violence and gore.

The case has divided the community. Protesters gathered outside the courthouse in the weeks leading up to the trial date, holding signs calling for rehabilitation over retribution and highlighting Rosa’s young age and reported mental health struggles. “He was a child himself—mental illness, not evil, drove this tragedy,” one supporter told local media. Defense attorneys pointed to neurological evaluations showing possible underlying conditions that may have contributed to the unthinkable act.

Rosa’s family has been torn apart. His grandmother, Isabel Acosta, described losing both her daughter and grandson in one horrific moment. Meanwhile, Rosa’s father and stepfather were interviewed by police in emotional footage released in May 2026.

Just days before the trial was set to begin, Rosa accepted a plea deal, pleading guilty to second-degree murder. On January 16, 2026, he was sentenced to 25 years in prison followed by 20 years of probation. In court, he simply said, “I’m sorry.” The deal avoided the mandatory life sentence he could have faced if convicted of first-degree murder.

Supporters who had protested for leniency expressed relief that Rosa would have a chance at rehabilitation and eventual review, while critics called the sentence a “sweetheart deal” for a brutal crime. The case continues to spark fierce debate about juvenile justice, mental health in the courtroom, and the limits of accountability for young offenders in Florida.
