Inaudible: The Disappearance of Sabrina Aisenberg
Sabrina Paige Aisenberg was five months old when she disappeared from her crib in Valrico, Florida, sometime between midnight and 6:42 a.m. on November 24, 1997. Her mother, Marlene Aisenberg, checked on her around midnight and found her sleeping normally. By the time Marlene returned that morning, Sabrina was simply gone. What followed was not just an unsolved disappearance but one of the most legally consequential failed prosecutions in recent American history, a case built almost entirely on secretly recorded audio that a federal judge would eventually rule was, for all practical purposes, inaudible.
A Crib Found Empty
The scene investigators found inside the Aisenberg home offered little immediate explanation. The residence's garage door and an interior door had both been left unlocked overnight, though there were no obvious signs of forced entry. Sabrina had last been seen wearing a lavender sleeper with a floral pattern, and a handmade blue and yellow blanket decorated with animal images, one she was known to sleep with regularly, was missing from the crib along with her. Investigators recovered an unidentified blonde hair and a shoe print near the crib itself, along with seven unidentified fingerprints found elsewhere inside the home. A neighbor reported hearing what may have been a baby crying around 1 a.m. that night, and the family's own dog, notably, never barked.
Suspicion Falls on the Parents
From the earliest days of the investigation, police focused heavily on Steve and Marlene Aisenberg themselves. Officers noted that the couple did not appear particularly upset during initial questioning, and their televised public appeal for information was widely perceived as emotionally flat and detached. Marlene later pushed back on this characterization directly, explaining that delivering that appeal had taken every bit of strength she had, and that she broke down in tears the moment the recording stopped, a moment the cameras had simply not captured. Polygraph results only deepened the ambiguity surrounding the couple, with Steve passing his examination while Marlene failed hers on two separate occasions. After the family retained defense attorney Barry Cohen, they limited their further cooperation with investigators, a decision that likely intensified police suspicion even as it reflected fairly standard legal advice for anyone facing this kind of scrutiny.
A Wiretap and a Devastating Claim
Just over two weeks after Sabrina disappeared, on December 13, 1997, law enforcement obtained permission to place electronic listening devices inside the Aisenbergs' own home, secretly recording their private conversations both in person and over the phone. Investigators believed they had probable cause to suspect the couple had killed their daughter, and in 1999, federal prosecutors formally charged Steve and Marlene with making false statements to investigators, built substantially around claims that the recordings had captured Steve discussing killing Sabrina. Both parents categorically denied any such statements had ever been made.
Tapes That Didn't Match Their Own Transcripts
The case against the Aisenbergs began to unravel once the actual recordings came under judicial scrutiny. A federal judge reviewing the evidence found that the recordings themselves were largely inaudible, and that the government's own transcriptions of those recordings simply did not match what could actually be heard on the tapes. A magistrate judge who separately reviewed the material described the recordings as unintelligible, finding nothing on the actual audio that corresponded to the damning statements prosecutors claimed the transcripts contained. In February 2001, with trial approaching, prosecutors dropped the charges entirely rather than proceed with evidence a court had already characterized in such stark terms.
An Extraordinary Government Concession
The fallout from the collapsed prosecution proved historically significant in its own right. The United States government formally conceded liability under the Hyde Amendment, a federal law allowing reimbursement of legal fees to defendants who can show they were prosecuted vexatiously, frivolously, or in bad faith. This concession was, by most accounts, the only instance of the Department of Justice acknowledging this specific standard since the Hyde Amendment's enactment. A district court initially awarded the Aisenbergs 2,680,602.22 dollars in attorney's fees connected to their defense, an amount later reduced on appeal to 1,298,980 dollars, still one of the largest such awards in the law's history.
A Family Rebuilding Elsewhere
In the years following their exoneration, Steve and Marlene Aisenberg relocated and rebuilt their lives working as real estate agents in Maryland. They have continued to maintain their complete innocence in the years since, with both of them stating plainly, in Marlene's own words, that they did not have any involvement in what happened to their daughter. The couple has remained married for 36 years, and Marlene has spoken candidly about learning, over time, how to manage the grief connected to Sabrina's disappearance without allowing it to define the rest of their lives, describing a process of pushing that grief down far enough to keep moving forward as a family.
Hope Through DNA
In the years since Sabrina's disappearance, the Aisenbergs have periodically been contacted by young women who believed, based on their own age and circumstances, that they might actually be Sabrina. Marlene has said she regularly receives Facebook messages along these lines, and multiple women have submitted DNA samples for comparison over the years. None of these tests have ever produced a match. Despite the repeated disappointments, Steve has said that each new possibility gives the family continued hope that Sabrina remains out there somewhere, and that she will eventually take a DNA test that finally confirms who she is.
A Case Still Open
The Hillsborough County Sheriff's Office has continued to describe Sabrina's case as an active and ongoing investigation even decades after her disappearance, and continues to ask that anyone with information come forward. Marlene has described the toll of the intervening years plainly, noting that even as the family has learned to function and carry on, they remain, in her words, still holding it together while waiting for Sabrina to come home, a wait that has now stretched across more than a quarter century.
Still Missing
Sabrina Paige Aisenberg has never been found, and the parents who were once the primary suspects in her disappearance were ultimately vindicated so thoroughly that their case became a landmark example of prosecutorial overreach, built on recordings a federal court determined could not actually support the allegations made against them. What remains, decades later, is a family that continues checking every hopeful DNA match that comes their way, a sheriff's office that insists the file remains open, and a little girl who would now be an adult in her twenties, her actual fate as unresolved today as it was the morning her mother found an empty crib in November 1997.
