A “joyful” 10-year-old Alabama girl was found dead soon after being reported missing — with another juvenile charged with her murder.

Katheryn Bigbee, 10, was reported missing just before 11 p.m. Friday, when police were called to an undisclosed address in Calhoun County, AL.com reported.

“Officers responded immediately to the residence,” Piedmont Police Chief Nathan Johnson said in a statement. “They tragically discovered a deceased juvenile inside the home.”

It remains unclear where the house was, or whether it was the young girl’s family home — but another juvenile was soon taken into custody and hit with murder charges.

Their identity and connection to Bigbee have not been disclosed due to their age.

Bigbee’s cause of death also remains unclear, with police saying the investigation was still ongoing.

“Our family has been torn to pieces, and we have lost the most amazing, sweetest little girl,” relative Blake Trammel wrote on Facebook.

“She was a light in any room she walked into. I cannot express the pain, guilt, and emptiness that has come from all of this. We don’t have answers, only more questions,” he added.

The girl’s school also recalled her as a beloved member of its community.

“Our entire Piedmont Elementary School family is grieving as we remember a sweet little girl who brought smiles, kindness, and a bright light to our halls each day,” the school said in a statement.

“Katheryn had a joyful, spunky personality that made her truly special,” the school said. “She was an enthusiastic reader and will be remembered for the happiness she shared so freely.”

“She will always be a part of our school family, and her memory will live on in the hearts of her classmates, teachers, and all who knew and loved her.”
