In the vehicle were Mansfield, her lawyer and boyfriend Sam Brody, the driver Ronnie Harrison, and three of her children: Mariska, her older brother Zoltan, and her older brother Mickey Jr.

The car, a 1966 Buick Electra, crashed into the back of a tractor-trailer that had slowed down due to a truck spraying mosquito fogger on the highway. The impact was catastrophic. The top of the car was sheared off, instantly killing the three adults in the front seat.

Miraculously, Mariska and her two brothers, who were asleep in the back seat, survived with only minor injuries. Mariska herself sustained a zig-zag scar on the side of her head, a permanent physical reminder of the event.

Five Shocking New Revelations from Mariska Hargitay's Investigation

For decades, Mariska Hargitay lived with only vague, fragmented memories of her mother and the crash. Her recent work, culminating in the documentary My Mom Jayne (premiering June 27, 2025, on HBO/Max), forced her to investigate the truth of her own family history, leading to several powerful and previously unknown details.

1. Mariska Was Accidentally Left Behind at the Crash Scene

Perhaps the most emotionally resonant and shocking detail revealed in the documentary is that three-year-old Mariska was accidentally left at the scene of the wreck. After the initial chaos, her brothers, Zoltan and Mickey Jr., were pulled from the wreckage and taken to the hospital.

It was her brother Zoltan, then 7, who realized his little sister was missing. He looked around and asked where Mariska was, prompting rescuers to return to the debris-strewn site to find her. This harrowing detail underscores the trauma and confusion of the night, highlighting how close Mariska came to being a forgotten victim.

2. The Discovery of Her Biological Father, Nelson Sardelli

In a separate but related personal investigation, Hargitay discovered in her twenties that the man who raised her, Mickey Hargitay, was not her biological father. Her birth father is actually Italian singer and comedian Nelson Sardelli.

This revelation came after she found a photo of Sardelli among her mother's memorabilia, leading her to "immediately know in her bones" that he was her birth father. The discovery added a complex layer to her identity, forcing her to reconcile the family she knew with a hidden truth about her origins. Hargitay has since forged a relationship with Sardelli, describing a recent Father's Day spent with him as "magical."

3. The Crash’s Eerie Connection to Her Own Motorcycle Accident

The 1967 tragedy was not the only near-death experience for the actress. At age 34, Mariska Hargitay was involved in a serious motorcycle accident that had an eerie, almost karmic, connection to her mother’s death.

The motorcycle accident caused a head injury that required surgery, leaving her with a scar on her head in the same area as the zig-zag scar she sustained in the 1967 car crash. She has spoken openly about how this later accident forced her to confront her fear and the trauma she had suppressed since childhood.

4. The Documentary is a Quest for Connection, Not Just Information

Hargitay has often stated that because she was so young, she has only the vaguest memories of Jayne Mansfield. The documentary, My Mom Jayne, is less about uncovering police reports and more about a daughter’s emotional quest to know the vibrant, complex woman who was her mother.

Hargitay uses the film to explore Mansfield’s life, career as a sex symbol, and intelligence, seeking to connect with the mother she never truly had the chance to know. It is an act of closure and a way to share Mansfield’s full story beyond the tragic headlines.

5. The Impact on Her Joyful Heart Foundation

The lasting emotional impact of the crash and the subsequent trauma is a driving force behind Hargitay’s advocacy work. Her organization, the Joyful Heart Foundation, was established in 2004 and is dedicated to healing, educating, and empowering survivors of sexual assault, domestic violence, and child abuse.

While the car crash wasn't directly related to her foundation’s mission, Hargitay has acknowledged that her own experience with profound trauma and loss fueled her deep empathy for victims. The ability to survive and thrive after a life-altering event has made her a powerful voice for those who feel powerless, turning personal tragedy into global advocacy.

Jayne Mansfield's Legacy and Mariska's Resilience

The "Mariska Hargitay car crash" remains a pivotal moment in Hollywood history, marking the end of one star’s life and the beginning of another’s journey through unimaginable trauma. The new details emerging in 2025, particularly the revelation that the young Mariska was left behind in the wreckage, add a chilling layer to the story of survival.

By directing and starring in My Mom Jayne, Mariska Hargitay has taken control of her narrative, transforming a decades-old tragedy into a fresh, ongoing story of discovery, identity, and profound resilience. Her willingness to investigate the most painful chapter of her life is a testament to the strength that has made her a beloved figure both on and off the screen.
