A 19-year-old young man broke down emotionally in a Miami-Dade courtroom this Tuesday as he faced the man who, when the young man was just five years old, took away his mother and two little sisters.
Michael Padrino Jr. took the stand during the sentencing phase of the trial against Alberto Sierra, the 42-year-old Cuban who admitted to murdering 29-year-old Gladys Machado and her daughters, Julia and Daniela Padrino, aged six and three, respectively, in November 2012.
The gut-wrenching moment was captured by various local media outlets, leaving several jurors in tears within the courtroom.
The Impact of a Lost Future
"You took them. You know you did," Padrino exclaimed during his victim impact statement, first addressing the jury about the future his family would never experience. "We were supposed to have more time together, more birthdays, more holidays, more days where nothing important happened... arguing over silly things, sitting around doing nothing... those were the best moments," he expressed.
He then turned directly to Sierra, who sat impassively, and shouted, "You! You took them! You know you did. You know what you did!" Attorneys had to swiftly remove him from the courtroom as many jurors, some crying, were escorted to another room.
A Son and Brother's Agony
Before confronting Sierra, Padrino described the impact of losing his mother and sisters as a young child. "My sisters were supposed to grow up, have their own lives, meet people, make friends, fall in love, create their own memories... and my mom was supposed to be there for all of it," he stated.
He also shared what he wished he could say to each of them: "I'd tell my mom thank you for everything she did for us, and tell Julia to remember how smart she was and how she made sure everyone knew it, and I'd tell Daniela that I still remember her exactly as she was. I'd tell them all that I love them," he declared in court.
A Fateful Decision
On November 10, 2012, Michael, then five, stayed with his great-grandmother in Homestead to watch the TV show "Caso Cerrado," while his mother and sisters went shopping with Sierra. That decision spared his life.
In a jealous rage over Machado receiving calls from another man, Sierra took the family by force to the home they had shared in the Flagami neighborhood, where he tied Machado's hands and suffocated her with a plastic bag from Sedano’s supermarket, before doing the same to the two little girls. Their bodies were found inside a closet three days later when a neighbor alerted police to a foul smell. Sierra’s recorded confession, played for the jury on Monday, included statements like, "I don’t know. I went crazy."
Voices Breaking the Silence
The girls' father, Michael Padrino Sr., also submitted a written statement to the jury. "I write because my daughters no longer have a voice in this world. Their lives, childhood, innocence, and every year they were meant to live were stolen from them. For 14 years, I’ve carried a pain no parent should ever bear," he said, visibly shaken.
Channon Castro, Machado's best friend, concluded her statement with words for the surviving son: "Mikey deserved to have his mother and sisters by his side. Nothing can take away the pain they carry, but I hope by speaking of who they were, their lives will never be forgotten."
The Jury's Critical Decision
In August 2026, Sierra pled guilty to three counts of first-degree murder and other charges, without a plea deal with the prosecution. This trial is not about his guilt, but rather the sentence: life without parole or the death penalty.
Under Florida's revised 2023 law, at least eight out of 12 jurors must vote in favor to recommend the death penalty. The defense, set to begin its case on Wednesday, argues mitigating circumstances due to Sierra's traumatic brain injury at age 12 that impacted his frontal lobe, a region associated with impulse control.
The jury has yet to make its recommendation.
