Jessi Combs, a professional racer and TV personality known for breaking land-speed records, died after a car crash Tuesday (Aug. 27) while attempting to go 500 mph to break a land-speed record. She was 36 years old.

KTVZ reports that the Harney County Sheriff’s Office was called to the scene of the crash around 4 p.m. Tuesday.

Details about the crash haven’t been released, however, authorities are reportedly investigating.

Combs—affectionally referred to as “the fastest woman on four wheels”—was reportedly trying to beat her own land speed record when she was tragically killed in a jet-powered car in Oregon.

Her previous record, set in 2016, was 478 miles per hour in the same desert where Tuesday’s crash happened.

She earned her nickname in 2013 after she broke a record held by Lee Breedlove since 1965 by reaching 398 miles per hour.

Jessi was also known as a TV personality who made notable appearances on shows like Mythbusters and Overhaulin’.

Just a few days ago, Combs shared a photo on social media as she prepared for this most recent speed record attempt.

“It may seem a little crazy to walk directly into the line of fire… those who are willing, are those who achieve great things,” she wrote. “People say I’m crazy. I say thank you ;)”

Terry Madden, a member of Comb’s crew, confirmed her death via Instagram Wednesday morning (Aug. 28), calling Jessi “the most amazing spirit that I have ever or will ever know.”

He added that he was the first one on the scene of her “horrific accident” and said everything “humanly possible” was done to save her.

Unfortunately we lost her yesterday in a horrific accident, I was the first one there and trust me we did everything humanly possible to save her!! I’m not ok, but she is right here keeping my going-I made her a promise that if this didn’t go well that I would make sure and do good with it, please help me with that, you are all going to see things on news please believe non of them.. we the family have drafted a release and it will come out today with more proper info, but I was just woke up by the media tracking me down and I need everyone of her true friends to do what she would want “take a deep breath, relax” and do good things with this. Please donate to nothing, I know there will be people try, we are finishing the documentary as she wished and the world will know the truth and her foundation will use those funds to do amazing things in this world and make her legacy live on properly. In the coming days her family and I will get the proper channels put together that you can then donate to that foundation but until you hear it from me wait please-I don’t want some asshole profiting off this (all ready had one try to sell us a video)… . .
