SPRING (CBDFW.COM) – The parents of a 16-year-old ejected from a car after she removed her seatbelt to take a selfie are turning their grief into action.

Kailee Mills had just left her home in Spring with friends to attend a Halloween party. She was riding in the backseat, and the party was only a mile away. Mills was a few blocks away from home, according to her parents, when the car she was riding in veered off the road. Just seconds before the crash, Mills had removed her seat belt to slide over in the backseat to take a selfie with her friend The car rolled over, Mills was ejected from the backseat of the car, and died instantly. Her three friends walked away with only minor cuts and bruises. Mills was the only one in the car not wearing a seat belt.

“We know if she had her seatbelt on, she’d still be here,” said father, David told The Independent.

Mills was a 4.3 GPA student at Klein Collins High School in Spring, and enjoyed spending her time helping other people and volunteering. Friends described her as having a contagious laugh and smile. She planned to attend Texas A&M University to pursue a career in biomedical science.

Mills’ parents said she was very good about wearing her seatbelt. In fact, they couldn’t recall one single time that they had to remind her to wear her seatbelt and never caught her without it on. He friends were all in shock because she was the one that always made sure everyone was buckled up and never put her car in drive until all of her passengers were buckled up.

Authorities believe the driver was speeding and lost control of the car, news station KTRK-TV reported.

The teen’s parents want their daughter’s death to serve as a reminder to others about the importance of wearing seat belts, and have started the Kailee Mills Foundation to do so.

Their goal is to prevent other families from having to go through the same pain and loss they’re going through, and carry out their daughter’s legacy in a way that she would have wanted by helping others. The foundation works to provide stickers for car windows and motorbike helmets across the region to remind drivers and passengers to buckle up.
