Florida Mom Killed Baby, Then Sold Her Belongings on Facebook the Same Day
In a shocking and deeply disturbing case, a Florida mother is facing first-degree murder charges after allegedly killing her 3-month-old daughter and selling the baby’s belongings on Facebook Marketplace just hours later. Tess Ann Britt, 26, of Oldsmar, Florida, was arrested on March 6, 2025, after an investigation linked her to the December 13, 2024, death of her infant daughter.
Florida Mom Killed Baby: What We Know So Far
According to the Pinellas County Sheriff’s Office, deputies responded to a 911 call about an unresponsive infant at Britt’s home on Meriden Avenue on December 13. The baby was transported to a hospital, where she was pronounced dead. A medical examiner later determined that the infant suffered multiple brain bleeds and a significant skull fracture, ruling the cause of death as blunt force trauma.
Authorities quickly focused their investigation on Britt, who was the sole caretaker of the child at the time of her injuries. Following months of evidence gathering, she was arrested and charged with first-degree murder.

She Sold Her Baby’s Car Seat and Swing on Facebook Hours After the Death
Perhaps the most chilling aspect of this case is that, on the very same day her baby died, Britt was actively selling the child’s belongings on Facebook Marketplace. Screenshots from a Facebook user, Nyiah Nelle, show messages confirming a transaction for a baby car seat and swing, which were sold the same day authorities believe the baby was killed.
In a viral post, Nelle shared her horror after later discovering the truth:
“This girl literally sold me her dead baby’s car seat & swing & kept writing me trying to get me to buy clothes & formula! Whole time the baby was dead.”
The revelation has sparked outrage across social media, with true crime groups and parenting forums expressing shock and disgust over Britt’s actions.
Social Media Erupts Over the Crime
Facebook crime groups and community discussions have exploded with outrage over the case. Users have called Britt’s actions “inhumane” and “beyond disturbing,” with many pointing out the chilling timeline of events.
One commenter wrote:
“She was posting baby items for sale WHILE HER BABY LAY DEAD. That is a whole new level of evil.”
Another added:
“I’ve seen a lot of messed up cases, but this one truly makes me sick.”
Her Pregnancy Announcement Resurfaces, Sparking More Outrage
As the case gained attention, people on social media uncovered Britt’s pregnancy announcement from August 2024. In the post, she shared excited photos with her husband, Peter Britt, celebrating the upcoming arrival of their twins, Gunner and Lana. She wrote about how she “couldn’t wait to meet them” and how “all the symptoms were worth it.” Family members and friends had flooded the comments with love and support, thrilled about the babies’ arrival.
Now, the resurfacing of that post has only deepened the shock and disgust. Many are struggling to reconcile the glowing mother-to-be with the woman now accused of violently ending her baby’s life.
“She acted like the happiest mom-to-be, and now we find out she did THIS? Absolutely horrifying.”
“Her family was so excited, and she was posting all these cute pregnancy pictures… then she turned into a monster.”
This revelation has only fueled the public’s anger, making the case even more haunting.
