Daveigh Chase Lilo & Stitch star Cause of Death revealed: The Tragic Fall of a Child Star

The entertainment world was rocked earlier this month when news broke that Daveigh Chase — the beloved voice of Lilo in Disney’s Lilo & Stitch and the haunting face behind Samara Morgan in The Ring — had died at just 35 years old. Now, the Los Angeles County Medical Examiner has officially revealed the cause of death, and the findings paint a heartbreaking picture of a life that unraveled far too soon.

The Official Cause of Death: AIDS and Substance Use

According to the Los Angeles County Medical Examiner’s Office, Daveigh Chase — born Daveigh Elizabeth Schwallier — died on June 16, 2026, from Acquired Immunodeficiency Syndrome (AIDS). Chronic polysubstance use was listed as a significant contributing condition. The manner of death was ruled natural.

The revelation came as a shock to many, as initial reports had pointed in a different direction. Her boyfriend, Roy Hernandez, who announced her passing to TMZ on June 17, had stated that Chase died from complications of meningitis and a blood infection that caused septic issues, ultimately leading to her body shutting down. Her father, John David Schwallier, had also initially cited bacterial meningitis and a blood infection as the cause when he spoke with The New York Times.

The Medical Examiner’s official findings, however, told a far more complex and devastating story.

A Downward Spiral That Began Young

Chase’s father, John David Schwallier, made a deeply painful revelation in the days after her death: his daughter had been battling drug addiction since she was just 13 years old. Her mother, Cathy Chase, offered additional context — she believed the addiction worsened significantly after a motorcycle accident around 2016, when Chase was prescribed oxycodone and other painkillers for a back injury.

“She was seeking drugs and was partying with the wrong people,” Cathy told The Daily Mail. “The drugs took hold of her… She went back to the streets and I couldn’t find her. I will live forever feeling I failed her.”

Cathy last saw her daughter in 2019. “She was completely gone, like, out of her mind,” she recalled.

The addiction cost Chase nearly everything. In her final years, she had become homeless, reportedly living in the downtown Los Angeles area. A disturbing video circulated in the days after her death, showing the former child star appearing barely conscious and looking emaciated on Skid Row. Her longtime manager, John Ryan, and her step-sister, Gaia Brown, had reportedly been working with a private investigator to locate her in the months before she died.

A Family Torn Apart

The father-daughter relationship between Chase and John David Schwallier had been strained for years. While he confirmed her death and spoke about her struggles, the two had been estranged for much of the period leading up to her passing.

Her boyfriend Hernandez, in a GoFundMe campaign set up in Chase’s final days, described the difficulty she had endured and the love he tried to give her:

“After a difficult childhood and a painful falling out with her family, Daveigh was bullied and struggled to find safety and happiness in downtown L.A. When we met, I promised to protect her and give her the love and comfort she deserved. Together, we found moments of happiness and hope.”

Chase had been admitted to a hospital in Los Angeles earlier in June for malnutrition before her condition deteriorated fatally. The GoFundMe, which raised questions from her former manager who was unfamiliar with Hernandez, was confirmed by him to be legitimate.

The Star She Once Was

To fully grasp the tragedy of Daveigh Chase’s death, one must understand the extraordinary heights from which she fell.

Born on July 24, 1990, in Las Vegas, Nevada, Chase showed a natural talent for performance almost from birth. She began singing and dancing at community events at the age of three, and by seven she had booked her first Hollywood job — a commercial for Campbell’s Soup. By eight, she was appearing in guest roles on major network television shows including Sabrina, the Teenage Witch, Charmed, The Practice, and ER.

Then came 2002 — a year that would define her career forever and cement her as one of the most remarkably talented child performers of her generation.

Lilo & Stitch (2002)

Chase provided the voice for Lilo Pelekai, the spirited and lovable Hawaiian girl at the heart of Disney’s animated hit Lilo & Stitch. The film was both a critical and commercial triumph, grossing over $273 million worldwide. Her performance was widely praised for its emotional depth and comedic timing. She won the Annie Award for Outstanding Achievement for Voice Acting in an Animated Feature for the role — beating out adult competitors at just 11 years old. She went on to reprise the role in sequels and the Lilo & Stitch: The Series television show, which aired from 2003 to 2006.

That same year, she also lent her voice to the English dub of Studio Ghibli’s acclaimed Spirited Away, voicing protagonist Chihiro Ogino — a film that went on to win the Academy Award for Best Animated Feature.

The Ring (2002)

In a stunning display of range, the same year she charmed audiences as Lilo, Chase terrified them as Samara Morgan, the pale, long-haired ghost at the center of Gore Verbinski’s horror blockbuster The Ring. Her performance was chilling, iconic, and unforgettable. She won the MTV Movie Award for Best Villain in 2003 — defeating adult nominees including Mike Myers, Colin Farrell, Willem Dafoe, and Daniel Day-Lewis. She was twelve years old.

Donnie Darko (2001) and Beyond

Before her 2002 breakout, Chase appeared in Richard Kelly’s cult psychological thriller Donnie Darko as Samantha Darko, the younger sister of Jake Gyllenhaal’s title character. From 2006 to 2011, she starred in 32 episodes of HBO’s acclaimed drama Big Love as Rhonda Volmer, a young woman corrupted by religious extremism — earning new praise for her ability to handle dark, complex adult material.

The Fade from Hollywood

By 2016, after appearing in the horror film Jack Goes Home, Chase largely withdrew from the entertainment industry. Her mother linked this withdrawal directly to the motorcycle accident and the painkiller prescription that followed. What began as physical pain relief spiraled into addiction, instability, and ultimately, tragedy.

Her former manager and step-sister had been trying to reach her for months before her death, reportedly employing a private investigator to track her down. The woman who had once been a household name to millions of children around the world had become invisible — lost in the streets of Los Angeles.

An Industry Mourns

Following her death, tributes poured in from across the entertainment industry. Lilo & Stitch co-directors Chris Sanders and Dean DeBlois honored her with artwork featuring Stitch, Scrump, and Pudge. Fans and colleagues alike remembered her not just for what she achieved on screen, but for who she was — a gifted child who deserved far better than the hand life ultimately dealt her.

A Life That Deserved More

The story of Daveigh Chase is not just a Hollywood cautionary tale. It is a reminder of what can happen when the pressures of early fame, family fractures, addiction, and systemic failures converge on a single life. She was a girl of extraordinary talent who voiced characters that brought joy to millions — a fearless Hawaiian child who believed in ohana, and a terrifying ghost who haunted a generation.

In the end, she deserved what Hernandez said she always wanted: “a place where we could live together, feel safe, and be happy.”

May she rest in the peace she never quite found here.
