Michael Tanzi, convicted nearly 25 years ago for the murder of Janet Acosta, a Miami Herald employee, is slated for execution on April 8 at Florida State Prison. This case, which shocked southern Florida in 2000, has resurfaced in the public eye due to last-minute legal efforts by Tanzi's defense team to halt the execution.
The Crime That Shook Miami and the Florida Keys
On April 12, 2000, Janet Acosta was enjoying her lunch break, reading peacefully in her van parked in a Miami park. It was then that 23-year-old Michael Tanzi forcibly entered the vehicle, punched her, pushed her aside, and drove off. For hours, Tanzi held Acosta captive as they traveled toward the Florida Keys.
During this grim journey, Tanzi bound and sexually assaulted Acosta, used her bank card to withdraw cash from several ATMs, and ultimately strangled her in a secluded area of Cudjoe Key. He abandoned her body and proceeded to Key West to meet with friends.
Acosta's disappearance was soon reported by her family. Her van was eventually found abandoned on Duval Street in Key West, a lively area bustling with tourists. Confronted by authorities, Tanzi confessed to the crime and led investigators to the location of Acosta's body.
An Undeniable Conviction and Death Sentence
In 2003, after pleading guilty to charges of first-degree murder, kidnapping, and armed robbery, Tanzi was unanimously sentenced to death by a jury. Since then, he has made numerous appeals, all of which have been denied. Governor Ron DeSantis of Florida signed the execution order on March 10, setting the date for April 8, 2025.
This execution will be the third in Florida this year. James Dennis Ford was executed in February for the 1997 murder of a couple, and in March, Edward James faced execution for the rape and murder of an eight-year-old girl and her grandmother in Seminole County.
A Last-Minute Legal Challenge: Tanzi's Health Concerns
As the execution date looms, Tanzi's defense has filed a new legal appeal. They argue that his physical conditions, including morbid obesity, sciatica, acid reflux, and sleep apnea, could complicate the lethal injection process. The current protocol does not account for dosage adjustments based on an individual's weight, they assert.
According to their filing, the sedative etomidate might not fully take effect, potentially leaving Tanzi "paralyzed but conscious" during the administration of sodium acetate, which could cause an "internal burning sensation" and prolonged suffering. They also warned that Tanzi might suffer from "pulmonary edema," leading to a sensation of suffocation, and that lying on his back could increase the risk of aspiration.
The defense concluded, "Executing Mr. Tanzi using the current protocols will likely cause severe illness and unnecessary suffering." They highlighted the logistical challenges of establishing intravenous access due to Tanzi's extreme obesity, which could lead to delays and increased agony.
State's Response: Protocol Upheld
The Florida Attorney General's office, led by James Uthmeier, responded forcefully, accusing Tanzi's lawyers of delay tactics. "Tanzi offers no support for his unfounded claim that the massive etomidate dose will fail," the prosecution stated. Uthmeier noted that the sedative has been used "repeatedly and successfully" in prior executions without weight-related issues.
They also pointed out that Tanzi had ample time to file such objections, arguing that doing so just a week before execution is a clear delaying strategy.
Death Penalty Debate in the United States
Tanzi's case has reignited the national debate over the death penalty and the humane standards that should be upheld in executions. While Florida offers two execution methods—lethal injection and the electric chair—recent years have seen growing controversy over the efficacy and potential side effects of the drugs used.
This debate extends beyond Florida. In South Carolina, a death row inmate chose execution by firing squad over lethal injection, fearing a slow and painful death. It marked the first execution of this kind in the state and the first in the U.S. in over 15 years.
With the execution date rapidly approaching, the final decision now rests with the Florida Supreme Court. If a stay is granted, the process will hinge on medical and legal evaluations of the risks involved in executing Tanzi. Otherwise, the state will proceed with the third execution of the year on April 8.
