A Michigan woman has been jailed following allegations that she brutally assaulted her 14-year-old daughter with autism, reportedly saying she “didn’t want this child anymore.”

Vangie Renee Averhart, 37, faces charges of murder in connection with the death of her daughter, Kylee Clark. According to court documents, Kylee succumbed to her injuries at a hospital in the Detroit area in July.

The cause of Kylee’s death was blunt force trauma to the back of her head. Prosecutors likened the severity of her injuries to those sustained in a high-speed car crash, as reported by the Metro Detroit News. Averhart allegedly provided various inconsistent stories regarding the origin of her daughter’s injuries.

Initially, Averhart claimed her daughter choked on a sandwich, later changing the story to a banana. She also attempted to implicate her boyfriend, though he successfully passed a polygraph test and was not present during the incident, according to the Metro Detroit News.

Prosecutors indicated that Kylee, who was unable to speak, was kept in a locked room. Allegedly, Averhart expressed to others her desire to be free of the child. Previous investigations by Child Protective Services had been conducted due to concerns regarding Kylee’s well-being, as reported by MDN.

Kylee’s family members told local NBC affiliate WDIV that she suffered the injuries at her home on July 7 and died five days later at a hospital.

“Kylee’s mother lied right from the get-go about pretty much everything. She’s just rotten,” her paternal great-uncle Jeffrey Clark told the outlet. “I mean, it’s her own flesh and blood.”

Clark said Kylee’s father had been trying to obtain custody of the girl in the months leading up to the alleged murder.

“And supposedly she said ‘you can have her, I don’t want her,’” Clark recalled. “[It’s] hard to fathom. I don’t know if it’s some vindictive thing on her part or if she’s just pure evil.”

Averhart remains in the Wayne County Jail without bond. Her next court date is scheduled for Nov. 26.

Kylee’s obituary said she “left an everlasting mark on the hearts of those who knew her.”

“Kylee had a vibrant soul and a beautiful way of experiencing the world. She loved music — it filled her days with joy and comfort — and she was always happiest when she had her favorite snacks nearby,” the obituary said. “She saw beauty in every color and brought brightness into every room with her spirit. With a love for textures, sensations, and using her hands, Kylee found joy in the little things many might overlook. Whether it was a soft blanket, a crunchy snack, or a rhythmic song, she embraced the world in her own unique way.”
