A 20-year-old woman died in a bizarre car accident in Georgia when the brake drum of another vehicle flew off and smashed her windshield.

According to local media outlets WTVC and Local 3 News, as well as social media posts from her siblings and a GoFundMe page, college student Autumn McClure was in the passenger seat of her boyfriend’s car as the two drove to Ringgold, Georgia, to drop off her younger brother at daycare.

McClure’s sister, Simone Matherly, wrote in a Facebook post that a brake caliper flew through the windshield of her car, “killing her almost instantly” in a “freak car accident.”

According to Local 3 News, the Ringgold Police Chief confirmed that the accident occurred on Wednesday morning, August 14, as she and her boyfriend were traveling south on I-75 from their home in Soddy-Daisy, Tennessee, just north of the state line.

The brake drum flew out of the bed of a truck and hit her in the chest and neck, according to the GoFundMe page organized by McClure’s brother Collin Le to help with funeral arrangements for the 20-year-old.

“Fall passed before emergency services could arrive,” the GoFundMe campaign states.

Ringgold police did not immediately respond to PEOPLE’s request for comment.

McClure was the runner-up in the class of 2022 at Soddy-Daisy High School, studied graphic design at Chattanooga State Community College and was a passionate lover of nature and concerts, according to her obituary.

The obituary goes on to say that donations received through the GoFundMe page — which had already raised over $2,500 of its $10,000 goal at the time of publication — will also benefit several conservation organizations.

Many of her friends and family members took to social media to share their thoughts about the 20-year-old’s life after her death. In a Facebook post, Matherly wrote that “even typing this feels like an out-of-body experience.”

“Losing a sibling is not something you like to think about. I thought about it when we were all grey and old, but not like this,” she wrote in part. “She would have turned 21 next month. She was going to graphic design school. She had so many plans and dreams. My family and I just can’t believe it. It still doesn’t seem real.”

McClure’s boyfriend Tyler Nunley wrote in a long caption on Instagram that she was “the brightest and most spectacular part of my life.”

“You have had such an incredible impact on my life by helping me become the person I am today. You were the most amazing person I will ever meet,” he wrote.

McClure’s twin sister Ivy McClure also wrote about her sister’s death on Instagram.

“I will miss you for the rest of my life,” she wrote in a post to her sister, among other things. “You have been my best friend since the day we were born. I will never find enough words to describe how much you mean to me, but I can say that I will always remember you for your kind heart, your humor, your intelligence, your happiness.”
