- Juvenile detention superintendent says the boy is being held in a pod with up to 16 juveniles
- MaKayla "BooBah" Dyer, 8, was shot and killed last Saturday; an 11-year-old boy is charged in her death
- "I want her back in my arms, this is not fair," the girl's mother says
White Pine, Tennessee (CNN)A little girl killed, allegedly because of a puppy.
That's what Jefferson County, Tennessee, Sheriff G.W. "Bud" McCoig said led to the Saturday death of 8-year-old MaKayla "BooBah" Dyer.
McCoig told CNN's sister network HLN that an 11-year-old boy asked to see the girl's puppy.
When she said no, the boy shot her dead, according to the sheriff.
The 11-year-old is being held on a first-degree murder charge in a juvenile detention center. The superintendent of that facility, Richard Bean, said that the boy -- the youngest ever held there on a murder charge that he knows of over his 44-year career -- is being held in a regular "pod" that holds up to 16 other juveniles who are between the ages of 12 and 17.
Bean described the boy as "very tiny," weighing about 55 pounds.
"It is the most pitiful case on both sides," Bean said.
Jefferson County District Attorney James Dunn told CNN his office will determine whether it believes the boy should be tried as an adult, acknowledging that there would be a "heavy burden" to convince a judge to transfer the case out of juvenile court.
"We don't have situations like this," the prosecutor said. "... So it is very difficult."
The public defender in the case, Edward Miller, told CNN affiliate WATE that "the court has ordered my client detained until (an October 28) hearing." He did not offer more comments beyond that.
Uncle: A 'lovable ... and typical 8-year old girl'
According to her obituary, MaKayla died just three weeks removed from her 8th birthday.
Her death shook up many in White Pine, a small town of just over 2,000 people located 40 miles east of Knoxville.
"My heart is aching because a little girl lost her life really young," Chasity Arwood, a neighbor of both the victim and the accused, told WATE. "My heart is aching, too, because a little boy is having to go through what he's having to go through."
The slain girl's mother, Latasha Dyer, choked back tears as she talked to the same news station.
"I want her back home, I want her back in my arms," she said. "This is not fair."
Hundreds attended a visitation for her Wednesday evening in Maynardville, where songs from the Disney hit movie "Frozen" were played -- just like MaKayla would have liked.
"She was a lovable, little, adorable and typical 8-year old girl that enjoyed life and loved everybody," great-uncle Kenneth Norton told CNN. " She didn't know (any) strangers ... and anytime that you were doing anything ... she wanted to be a part of it."
