A Miami-Dade courtroom fell silent Friday as 15-year-old Derek Rosa learned he will spend most of his adult life behind bars for killing his mother in their Hialeah apartment. Rosa was sentenced to 25 years in state prison and 20 years of probation after pleading guilty to second-degree murder in the stabbing death of his mother, Irina Garcia. Prosecutors said Rosa, who was 13 at the time of the October 2023 attack, stabbed Garcia 46 times as she slept. Her newborn daughter, lying in a nearby crib, was not harmed. Rosa spoke only two words to the court, saying, "I'm sorry," before Judge Richard Hersch accepted the plea.
Plea deal and sentence
Rosa changed his plea on Jan. 16, accepting a deal that took a first-degree murder trial and a possible life sentence off the table. Under the agreement, he will serve 25 years in state prison followed by 20 years of supervised release. As part of the terms, the court ordered that he have no contact with his stepfather or his infant sister, according to Local10.
What prosecutors say
During the hearing, prosecutors outlined evidence they said left little room for doubt. They presented audio and court filings showing that after the stabbing, Rosa called 911 and later admitted to the killing in a recorded police interview. Investigators said he took a photo of Garcia's body, snapped a selfie of his bloodied hand, and sent those images to a friend. A forensic review of his phone also turned up disturbing internet searches, including "where is the best place to stab someone" and "can a knife cut through bone," according to Oxygen.
Family reaction in court
The most emotional moment in court came when Rosa's stepfather, Frank Ramos, chose to address him directly. Ramos described Garcia as "a loving mother" and said the killing had "destroyed" their family. Miami-Dade State Attorney Katherine Fernandez Rundle said Rosa "admitted" to the stabbing, and prosecutors argued that the evidence backing that admission was overwhelming, according to NBC 6 South Florida.
Legal context
Rosa's defense team had tried to keep his police statements out of court, moving to suppress them, but a judge rejected that effort before the plea was entered. Coverage of the case notes that the plea agreement includes a requirement for the court to evaluate Rosa's mental health needs before any future release, which could involve residential treatment, according to CourtTV. By pleading guilty to second-degree murder, Rosa avoided a potential life term but still faces decades in prison.
Aftermath
Public records and local reporting show that Rosa was moved from the Metro West Detention Center to Suwannee Correctional Institution in northern Florida. State records list his estimated release date as Oct. 5, 2048, according to Univision. The case continues to echo through Hialeah, as neighbors and relatives struggle to square the horrific details with the quiet teen they thought they knew.
