The loss of a loved one is always difficult, but losing someone at a young age feels especially heart-wrenching. This is the sentiment many are experiencing after the recent passing of Lizzy Muci, the star of “Street Outlaws: No Prep Kings.”

Lizzy was only 33 years old when she passed away, following a diagnosis of stage IV breast cancer. Her father took to Facebook on June 27 to share the heartbreaking news.

He wrote: “Surrounded by her family, in the comfort of her own home, Lizzy was called to heaven at 11:25pm tonight. Thank you for all the prayers and support throughout her battle. At this time, the family would like to have time to process, grief (sic) and make arrangements in peace. We will give an update as soon as we have information to share.”

Lizzy had publicly shared her breast cancer diagnosis in an Instagram post last year.

In 2023, the young racer was diagnosed with triple-negative stage 4 breast cancer, which had already spread to her liver and lymph nodes by the time it was discovered.

Throughout her battle, Lizzy remained candid about the various treatments she underwent. She even traveled to Germany to seek a specialized treatment targeting her liver.

Lizzy first gained fame appearing with her father, Pat, on the Discovery Channel series “Street Outlaws: No Prep Kings.” She went on to win several Pro Street World Championships.

May she rest in peace.
