11 year old boy murders an 8 year old girl over a puppy

An 11-year-old boy has been charged with  first degree murder after he allegedly shot an eight year old girl in a row about a puppy on Saturday evening in White Pine.
Officers responded to the call at 7:26 p.m. Saturday.
The boy is accused of killing McKayla Dyer near her home after asking to play with her dog.
After she refused he is said to have gone back into his house and fired at her with his father's 12-gauge shotgun.
According to her mother, McKayla Dyer, 8, was found lying on the ground with a gunshot wound to her chest. She was taken to Morristown-Hamblen hospital, where she later died.

“She was a precious little girl, she was a mommy’s girl, no matter how bad of a mood you were in she could always make you smile,” said McKayla Dyer’s mother, Latasha Dyer.

According to ABC, Both children were White Pine Elementary students according to Sheriff McCoig.
 The shooting wasn’t the first time their family had problems with the boy, according to Latasha Dyer.

“When we first moved to White Pine, the little boy was bullying McKayla,” Latasha Dyer said. “He was making fun of her, calling her names just being mean to her, I had to go the principal about him and he quit for a while and then all of a sudden yesterday he shot her.”

Latasha Dyer says she’s heartbroken and their entire family is devastated.

“I want her back in my arms, this is not fair, hold and kiss you’re babies every night because you’re never promised the next day with them,” said Latasha Dyer. “I hope the little boy learned his lesson because he took my baby’s life and I can’t get her back.”
