Hollywood usually gives us a clean narrative. Someone is the hero; someone is the villain. But when you look at what happened to Mariah Carey’s sister, Alison Carey, the story doesn't fit into a tidy box. It’s messy. It’s heartbreaking. Honestly, it’s a tragedy that spanned decades before ending in a way that sounds like something out of a gothic novel.
In late August 2024, the world woke up to a headline that felt statistically impossible. Mariah Carey, the elusive chanteuse herself, announced that both her mother, Patricia, and her sister, Alison, had died on the very same day.
One day. Two losses.
“My heart is broken,” Mariah said in her statement. It’s the kind of double-hit that leaves people reeling, regardless of how much money or fame they have. But for those who have followed the Carey family soap opera for years, the death of Alison wasn't just a sad note—it was the final chapter of one of the most fractured sibling relationships in pop culture history.
The Tragic End: What Happened to Mariah Carey's Sister in 2024
Alison Carey was 63 years old when she passed away. While Mariah’s team remained relatively tight-lipped about the specifics, reports eventually clarified that Alison had been in hospice care. David Baker, a friend and patient advocate for Alison, told reporters that her health had declined quite rapidly in the weeks leading up to her death.
She died from complications related to organ function. Specifically, it was reported that she had been battling liver cancer.

For years, Alison lived a life that was the polar opposite of her sister’s "glambellished" existence. While Mariah was selling out stadiums and living in penthouses, Alison was often struggling with homelessness and substance use disorder in upstate New York. By the time she entered hospice, she was living in a modest home in Coxsackie, about 120 miles north of New York City.
It’s easy to look at the "same-day" death of her mother and sister as a poetic, if tragic, coincidence. But the reality is that Mariah and Alison hadn't spoken in years. Decades, actually.
A Lifetime of "Prickly" Bridges and Burned Foundations
To understand what happened to Mariah Carey’s sister, you have to go back to Mariah's 2020 memoir, The Meaning of Mariah Carey. This book was the final nail in the coffin for their relationship. In it, Mariah didn't hold back. She referred to Alison as her "ex-sister."
That’s a heavy term.
Mariah alleged that when she was only 12 years old, Alison—who was eight years older—drugged her with Valium and even tried to "pimp her out" to a boyfriend. She also claimed Alison threw boiling tea on her, causing third-degree burns. These aren't just "we don't get along at Thanksgiving" problems. These are deep, traumatic scars.

Alison, for her part, fired back. She sued Mariah for $1.25 million, accusing the singer of "immense emotional distress" and calling the allegations in the book "vicious" and "despicable." She claimed she was already struggling with her mental health and that Mariah’s book was a calculated attempt to humiliate a "penniless" woman.
The Brain Injury That Changed Everything
One detail often overlooked is a horrific incident from 2015. Alison was the victim of a home invasion in her Long Island home. Someone attacked her with a baseball bat.
She survived, but she suffered a traumatic brain injury.
Between the physical trauma of that assault, her long-term health struggles, and the legal battles with her sister, Alison’s final decade was incredibly grim. She was a woman who seemed to be constantly reaching out for a lifeline that never quite stayed taut.
The Reality of the "Ex-Sister" Label
People often ask why Mariah didn't just "help" her. It’s the first question everyone has when they see a billionaire with a sibling in poverty. But Mariah's perspective was one of self-preservation. She wrote that for her own sanity, she had to "rename and reframe" her family.

She felt that Alison and her brother, Morgan, saw her only as a "cash cow with a wig on."
It’s a classic cautionary tale of what happens when one person in a dysfunctional family becomes the most famous person on earth. The gravity of that fame either pulls everyone together or rips them into pieces. For the Careys, it was the latter.
Despite the lawsuits and the "ex-sister" label, there was a glimmer of something human at the end. Reports suggested that while they were estranged, Alison’s children were able to see her before she passed. And Mariah, in her grief, acknowledged the tragedy of the "turn of events" that took both women from her.
What We Can Learn From This Family Tragedy
The story of Alison Carey is a reminder that money doesn't fix generational trauma. Sometimes, it actually makes the walls between people thicker.
If you're looking for the "actionable" takeaway here, it's about the complexity of boundaries. We often talk about "cutting off toxic family" as a TikTok trend, but the Carey story shows the heavy, lifelong weight of that decision.
- Acknowledge the Nuance: It is possible for someone to be both a victim and a source of pain. Alison had a "tough life," as her friends said, but Mariah clearly carried deep wounds from their childhood.
- Health Advocacy Matters: Alison’s final weeks in hospice were managed by advocates. Even when family is out of the picture, having a support system—legal or social—is vital.
- Estrangement is Heavy: Don't judge the "why" of a family's distance. We rarely know what happens behind closed doors, especially doors as gilded as Mariah's.
The legal battle between the sisters remained unresolved at the time of Alison's death. It’s a quiet, somber end to a very loud and public feud. Ultimately, Alison Carey's life was a series of "cheap bargains," as Mariah put it, but also a life of survival in the shadow of a sun that was perhaps too bright to stand near.
If you find yourself in a similar situation of family estrangement, the best path forward is often seeking professional mediation or trauma-informed therapy before the "same-day" headlines become your reality. It’s about finding peace while people are still here to hear it.
