1. The Unprecedented Double Tragedy of August 2024

The most shocking and recent update in the Mariah Carey family saga is the simultaneous passing of two immediate family members. In August 2024, both Alison Carey and her mother, Patricia Carey, died on the same day.

Mariah Carey herself confirmed the devastating news, describing it as a “tragic turn of events.” While the causes of death were separate—Patricia at 87 and Alison at 63—the timing created an almost unbelievable layer of tragedy and complexity for the singer to process.

Alison, who had been struggling with serious health issues for years, passed away while in hospice care in Greene County, New York. Her death was attributed to complications with organ function, with some reports specifically citing complications from liver cancer.

2. Years of Estrangement and the Lawsuit Over Mariah’s Memoir

The relationship between the two sisters was estranged for decades, a painful reality Mariah addressed candidly in her 2020 memoir, *The Meaning of Mariah Carey*. She described her sister as “disturbed” and detailed traumatic childhood incidents involving Alison.

The memoir’s publication led to a highly publicized legal battle. In 2021, Alison Carey sued her younger sister for emotional distress, seeking $1.25 million in damages. Alison’s legal filing claimed that the book’s description of her caused “immense emotional distress” and “public humiliation” due to her fragile health and mental state. This lawsuit underscored the deep, unresolved trauma within the family, which continued until Alison's death.

3. The Complex Relationship with Brother Morgan Carey

Alison was not the only sibling with a highly strained relationship with the pop diva. Mariah's older brother, Morgan Carey, has also been publicly critical and legally antagonistic towards the singer.

Morgan also filed a lawsuit against Mariah over claims made about him in *The Meaning of Mariah Carey*. He claimed the book painted him as a violent individual and a drug dealer, which he vehemently denied. The legal battles with both Alison and Morgan highlighted the profound and public family drama that has shadowed Mariah's career, confirming that the estrangement was a three-way dynamic, not just between the sisters.

4. Alison’s Struggles with Addiction and Health Issues

Alison Carey’s adult life was tragically marked by a long battle with drug addiction, which Mariah has publicly acknowledged as a contributing factor to their broken relationship.

Her struggles led to numerous public incidents, including arrests. In 2016, Alison was arrested for prostitution in Saugerties, New York, where she allegedly used lyrics from Mariah’s hit song “Fantasy” to solicit sex. Furthermore, Alison suffered a traumatic brain injury during a 2015 home invasion on Long Island, which severely impacted her health in the years leading up to her death. These health and legal crises often led her to make public pleas for help from her wealthy sister, though Mariah rarely responded publicly.

5. The Biracial Family Dynamic and Childhood Trauma

Mariah Carey has often spoken about the tumultuous childhood she, Alison, and Morgan experienced, which she attributes to the racial tensions surrounding their parents' interracial marriage—her father, Alfred Roy Carey, was of African-American and Venezuelan descent, and her mother, Patricia Carey, was Irish-American.

The family struggled to integrate into their predominantly white Long Island community, leading to deep-seated issues. Mariah claims that Alison’s traumatic experiences began early, and she was a victim of abuse. This shared, difficult family history is the foundation of the complex web of love, resentment, and estrangement that defined their adult lives.

6. Mariah’s Silence and the Public Scrutiny

Despite the public knowledge of Alison's declining health and financial struggles, Mariah Carey maintained a strict distance, reportedly not visiting her sister even when aware of her critical condition. This choice has been a point of intense public debate and scrutiny, with some criticizing Mariah for her perceived lack of compassion and others defending her decision to protect herself from a toxic, abusive relationship.

Mariah's silence was a deliberate boundary, one she felt necessary to maintain her own well-being and stability. The double tragedy of 2024, however, has forced the star to confront the finality of their broken bond, adding a layer of profound grief to her already complex personal life.

7. The End of a Bitter Chapter and the Remaining Family Battle

Alison Carey’s death marks the end of one of the most publicly bitter sibling feuds in Hollywood. However, the family drama is far from over. As of late 2025, Mariah is still navigating the legal challenges posed by her brother, Morgan Carey, regarding the claims in her memoir.

The singer’s willingness to open up about her family’s painful history in her memoir, while therapeutic for her, created a new set of legal and emotional battles with her siblings. The passing of both Alison and Patricia Carey within hours of each other serves as a tragic, final punctuation mark on a lifetime of deep-seated family trauma, leaving Mariah to navigate the aftermath and the remaining legal fight with her brother, Morgan, in the years to come. The ultimate legacy of Alison Carey is a cautionary tale about the devastating impact of addiction and unresolved family trauma, even in the shadow of extraordinary fame.
