After approximately seven hours of deliberation, a jury in Miami-Dade County has recommended the death penalty for Alberto Sierra, a 42-year-old Cuban man who admitted to killing his wife, Gladys Machado, and her two young daughters, Julia and Daniela Padrino, back in November 2012. The tension in the courtroom was palpable as the decision was announced this past Tuesday, October 20.
The verdict came nearly 14 years after the horrific triple homicide, leaving the victims' families in a state of anguish. Michael Padrino Jr., Machado's surviving son, reportedly trembled while waiting for the jury's recommendation, as reported by local media.
Prior to the verdict's announcement, Judge Marisa Tinkler Mendez urged those present to remain composed. The jury votes were then revealed for each victim:
- Gladys Machado, 29: 11 votes for the death penalty, 1 against.
- Julia Padrino, 6: unanimous decision by all 12 jurors in favor of capital punishment.
- Daniela Padrino, 3: 8 votes in favor, 4 against.
Each outcome met Florida's legal threshold for recommending the death penalty. However, the jury's recommendation is not the final sentence. The ultimate decision lies with the judge, who is scheduled to hold a hearing on November 2.
The Wait and the Surviving Son's Distress
The day was consumed by the jury's deliberations following several weeks of testimonies and closing arguments presented by both the prosecution and defense on Monday. According to Univision Miami, the jury took about seven hours to reach a decision, with tension peaking just before the announcement.
Michael Padrino Jr., who was only five years old when he lost his mother and sisters, was present. Now 19, he awaited the jury's recommended sentence for the man who had confessed to the murders. The television report described him as visibly shaking, overwhelmed with anxiety, while the judge called for order before reading the verdict.
A Crime That Shocked Miami-Dade
The tragic events unfolded on November 10, 2012, in the Flagami neighborhood. Sierra and Machado, who were in the process of separating, had taken the children to the Mall of the Americas earlier that day. A phone call to Machado from another man reportedly sparked Sierra's jealousy, leading him to forcibly take the family to their shared home.
There, Sierra tied Machado's hands with nylon rope, tortured her for her phone password, and suffocated her with a plastic bag from Sedano's grocery store. He then killed Julia, who witnessed her mother's murder, and Daniela, who was asleep at the time. The prosecution also alleges Sierra sexually assaulted the bodies of Machado and Julia.
Their bodies were discovered three days later inside a closet in the master bedroom, after a neighbor reported a foul odor. Sierra was apprehended on November 19, 2012, confessing to the crimes when confronted with DNA evidence.
In his recorded confession, he described how he killed Julia: "She saw her mom was dead and started crying and screaming. I grabbed the Sedano's bag and put it over her face."
Trial Developments: Testimonies and Jury Dynamics
Nearly 14 years after the murders, Sierra pleaded guilty in August 2026 to charges including three counts of first-degree murder, three counts of kidnapping, two counts of corpse abuse, and armed burglary, without a plea deal from the prosecution.
One of the most poignant moments came when Michael Padrino Jr. directly addressed the accused in court: "You! You took them! You know you did it. You know what you did!" At the time of the murders, Padrino was spared because he had stayed with his great-grandmother watching "Caso Cerrado."
In his testimony, he described the void left by his mother and sisters: "We were supposed to have more time together, more birthdays, more parties, more days where nothing important happened."
A juror was also dismissed from the trial due to emotional distress. The man, a cancer survivor, reported insomnia and that the process was affecting him and his spouse.
