The true-crime docuseries Somebody Knows Something recently turned its attention to one of Florida’s most puzzling missing child cases. The episode titled “The Baby in the Yellow Blanket” aired on Freeform and Hulu on August 10, bringing renewed focus to the 1997 disappearance of five-month-old Sabrina Aisenberg. Nearly three decades later, the case remains unsolved with no clear answers about what happened to the infant who vanished from her crib in Valrico, Florida.
The Night Sabrina Aisenberg Vanished From Her Crib
The Aisenberg family lived a normal life in Valrico, a small town near Tampa, Florida. On the night of November 23, 1997, Marlene and Steve Aisenberg tucked their three children into bed. Their oldest son William was eight years old, daughter Monica was four, and baby Sabrina was just five months old.
Everything seemed normal when Marlene checked on Sabrina around midnight. But the next morning, everything changed.
Marlene Aisenberg woke up around 6:30 a.m. on November 24, 1997, and went to check on her baby daughter. The crib was empty. Sabrina was gone, and so was her handmade blue-and-yellow blanket with animal images and yellow piping.
The parents searched the house and found the garage door and the door from the house to the garage both wide open. There were no signs of forced entry, suggesting someone had slipped in through the open garage.
Marlene called 911 at 6:42 a.m. that morning. Authorities arrived quickly and searched the neighborhood, but there was no trace of the baby.
Evidence That Pointed to an Intruder
Investigators found several pieces of evidence suggesting someone had taken Sabrina from her home. A boot print was discovered near her crib. An unidentified blonde hair was found in the crib. Seven unidentified fingerprints were also collected from the scene.
Sabrina had distinct features that could help identify her. She had blue eyes and brown hair. A birthmark shaped like the letter “Y” was located on the back of her shoulder.
Despite these clues, investigators never found a solid suspect. No one was ever conclusively linked to the disappearance.
Investigation Turned Toward the Parents
The case took a sharp turn when authorities began focusing on Steve and Marlene Aisenberg as possible suspects. Some people noticed what they considered strange behavior from the couple during a press conference where they pleaded for their daughter’s return.
A pediatrician also noticed something unusual in baby pictures of Sabrina. The doctor saw missing hair from the left side of her head and a bruised left eye, which raised questions about possible harm.
Just 16 days after Sabrina disappeared, authorities received permission to wiretap the Aisenberg home. They recorded conversations for 79 days, gathering 2,600 conversations across 55 audio recordings.
Prosecutors claimed that some conversations touched on Sabrina’s disappearance. They said Steve Aisenberg allegedly confessed to killing his daughter while under the influence of drugs.
However, a federal judge later ruled that many of the tapes were inaudible and others were taken out of context. In February 2001, all charges against the Aisenbergs were dropped by the prosecution.
The couple had also faced federal perjury charges earlier, but those charges also fell apart.
New Age Progression Image Released in 2026
The National Center for Missing and Exploited Children (NCMEC) released a new age-progression image of Sabrina Aisenberg in June 2026. The image shows what Sabrina might look like today as an adult, nearly 28 years after she disappeared.
Christi Andrews, the forensic artist who created the image, explained that the goal is to spark recognition. She studies family photographs, identifies shared features, and uses digital tools to create realistic representations of what missing children may look like years later.
John Bischoff, vice president of NCMEC’s Missing Children Division, stated that age-progression images can lead to critical new information. The organization hopes someone will recognize Sabrina or that Sabrina herself might see the image and come forward.
The release of the image came just before what would have been Sabrina’s 29th birthday on June 27.
The Aisenberg Family Continues to Hope
Steve Aisenberg spoke about the family’s ongoing pain and hope. He said the family has never stopped looking for their daughter.
“We woke up, and she was gone. She was taken out of her room. She wasn’t in our house. She hadn’t started to walk. Someone came in and took the most precious thing that could have been taken.”
Steve Aisenberg added that after 28 years, they still believe answers are possible.
“After 28 years, we still believe answers are possible, and we ask the public to take a moment to look closely and share this image and call in with information that will help bring her home.”
He also delivered a direct message to his daughter:
“Sabrina, we love you, we miss you and we look forward to the day we are reunited as a family.”
Marlene Aisenberg previously spoke about the lasting impact of her daughter’s disappearance.
“It’s a process, it’s something we live through every day still, and we will continue to live through it until she’s home with us.”
Legal Battle Over Case Files Continues
The case made news again in October 2025 when a Tampa attorney fought for access to case files. Michael Trentalange, an attorney who was friends with the late Barry Cohen (who represented the Aisenberg family), has been trying to review the documents for years.
Trentalange made public records requests in 2019 and 2021 but was told the investigation was still ongoing. He sued to gain access and won his case. The sheriff’s office appealed and lost.
In October 2025, a judge found the Hillsborough County Sheriff’s Office in contempt for not following the court’s ruling to release the records. The sheriff’s office had provided 516 pages of digitized documents, but thousands of documents, photos, video, and audio recordings remain.
Judge Cheryl Thomas expressed frustration with the delays.
“This case is 27 years old. It is unclear why this process of redacting, editing wasn’t started in the beginning.”
She ordered the sheriff’s office to set up a schedule for Trentalange to review the files.
Trentalange believes the public records could help solve the case.
“In fact by revealing it to the public, we might actually solve this case.”
He added:
“By revealing it to the public, we may actually solve this case if the public learns some information that was previously kept from it.”

What Happened to Sabrina Aisenberg?
The simple answer is that no one knows for sure. Despite extensive searches, countless leads, and years of investigation, Sabrina Aisenberg has never been found. No suspect has been conclusively linked to the disappearance, and no physical evidence has provided definitive answers.
The case has drawn national attention over the years, including a feature on the television show America’s Most Wanted. But the case went cold, and the Aisenberg family never got answers.
Investigators still do not know what happened to Sabrina or where she is located. Authorities have not confirmed any active suspects.
