Amazing video shows 13-year-old Florida Honors student talking calmly to 911 operator after calling to say he KILLED his mother while she slept, weeks after she gave birth to a baby girl
Shocking new doorbell surveillance footage has revealed the chilling final interactions between a mother and son – before he confessed to brutally stabbing her to death alongside her newborn baby girl.
Derek Rosa, 13, is initially seen quietly chatting with his mother, Irina Garcia, 39, in their living room as she cradled her baby, asking her in Spanish, “Why do you always tell me, 'Don't run?'
Hours later, Rosa was captured on the same doorbell camera after his mother was murdered, calmly asking a 911 dispatcher, “I see officers, should I leave?” Should I leave my house?'
Prosecutors also presented images allegedly taken by Rosa immediately after he stabbed his mother more than 40 times — including a smiling selfie with what appeared to be blood on his hands.
Separate footage previously shown in court showed Rosa confessing to the crime, where he told detectives: “I woke up, grabbed one of the kitchen knives and went to her room… I killed her.”
Despite the recording, Rosa has pleaded not guilty. His defense has tried to delay his trial, saying they are waiting for evidence from the prosecution, and he will have a status hearing on April 17.

The new Ring doorbell footage emerged this month as Rosa's case moves through the courts, with prosecutors insisting they are ready for a trial, reports NBC Miami.
Rosa is seen talking to his mother as if nothing was wrong while she sits in a chair with her baby.
He is then seen returning to the apartment some time later, where his mother was still sitting in the chair and still alive.
The footage then cuts back to the moments after Garcia was stabbed to death in her bed, as her son spoke in a calm voice to a 911 dispatcher.
He tells them his apartment number, 201, before continuing, “There are cops. I see officers. Am I leaving? Should I leave my house?'
“No – don't leave, don't leave,” the dispatcher replied in a harsh tone. “Stay where you are in your apartment.”
The end of the clip showed sirens and lights entering his apartment complex, where officers would find Garcia stabbed to death dozens of times in her bed.
Garcia, who had given birth just two weeks earlier, was killed as her baby slept next to her in her crib. The child was unharmed.

At an earlier hearing, prosecutors presented disturbing babycam footage from the room, which showed the 13-year-old looming over his mother's bed moments before they allege he killed her.
Derek was seen in a terrifying black and white image released in December 2023, with the time stamp being 11pm – half an hour before he called 911 to report the murder.
At 10:23 p.m., another terrifying image from before the murder showed Garcia in bed, with her 14-day-old baby in her arms.
After the murder, investigators say Rosa sent an online friend a selfie in which he stuck out his tongue and smiled while showing a sign with his blood-spattered hands.
Harrowing images of a pink-handled knife covered in blood were also shared in court at an earlier hearing, with dried blood also appearing to cover the blade.
During his call to 911, Derek said, “I have blood on my hands.”
When asked if his mother is still breathing, he replies: “She's dead ma'am… there's blood on the floor… I took pictures and told my friends, was that bad?”
The teen was arrested and taken into custody that evening, and he also appeared to confess to the murder while being questioned by detectives.
Footage shows Rosa calmly nodding yes when a Hialeah police detective asks him if he killed his mother.
“I woke up, grabbed one of the kitchen knives and went into her room… I killed her,” he said in the interview.

The teenager was seen describing the size and color of the knife he allegedly used to commit the murder
When asked what type of knife was used in the murder, he casually said it was a large kitchen knife with a purple handle, matching the images of the murder weapon presented by prosecutors.
The detective further wondered, “Did your mother sleep?” and Rosa confirmed: 'Yes, she was sleeping'.
The video also shows the teen showing detectives his bloody hands and pointing to his neck when asked where he stabbed his mother.
When asked why he did it, Rosa then asked to go to the bathroom and for a lawyer. No motive for the stabbing has been determined.
His family have expressed their shock at the alleged murder, saying Rosa was a “good boy” and that “no one could imagine this would ever happen.”
Rosa has pleaded not guilty to the crime, but his lawyers have yet to raise any possible mental health issues in his defense.
He was initially held at the Miami-Dade Juvenile Detention Center for two weeks after his Oct. 12 arrest until his charge was upgraded to first-degree murder by a grand jury and he was transferred to Metro West.
He will be tried as an adult.
Rosa's attorney, Dayliset Rielo, issued a brief statement when asked by NBC Miami about the new Ring doorbell videos.
“Today would have been Irina's 40th birthday, my prayers are constantly with the family and I hope that wherever Irina is in heaven, she will continue to give them strength and protection,” the statement read.
