Girl, 12, ‘suffocates 8-year-old cousin to death then cleans up victim & repositions body’ as ‘murder’ caught on cam

A 12-YEAR-OLD girl has been charged with murder after her 8-year-old cousin was allegedly suffocated to death.

Prosecutors have said a video supposedly showed the incident in Humboldt,

, around 80 miles northeast of Memphis.

The teen, who turns 13 next week, has been charged with first-degree murder and tampering with evidence.

Officials have said a video allegedly showed the teen suffocating her cousin Demeria Hollingsworth on July 15.

Prosecutors added that the video came from home security footage and said the incident supposedly occurred in the bunk bed the two children shared.

The District Attorney General, Frederick Agee, said the teen supposedly used bedding to suffocate the victim as she slept, in a Facebook post on the office’s page.

He added the suspect then cleaned her cousin and repositioned her body.

These children were together as they had been spending the summer with their grandmother.

The victim’s mother, Rayana Smith, said the issue between the girls came from an argument about an iPhone, according to Fox affiliate WXIN.

Smith shared emotional words as she remembered her daughter.

“She liked to read books, go swimming, play outside, ride her bike every day, play with the kids in the neighborhood, play with my friends’ kids,” she said.

“My baby was sweet.”

“She did nothing to deserve for her life to be taken,” the mother added.

“She was only 8 years old. She just turned 8 in April.”

District Attorney General Agee, said his office had petitioned Juvenile Judge Mark Johnson to try the suspect as an adult, according to WXIN.

“I consider this to be one of the most disturbing violent acts committed by either an adult or juvenile that my office has prosecuted,” he wrote.

She did nothing to deserve for her life to be taken."

Agee said under the state’s current laws the suspect, if convicted, would be free from further detention when they turn 19 years old.

He also added that neither the victim nor the suspect were from Humboldt.

The victim's mother has created a GoFundMe for her daughter's funeral service.

"I never imagined anything like this would happen and now find myself trying to fund a funeral," she wrote on the page.

District Attorney General Agee said his office could no longer comment on the case due to a gag order issued by the courts, according to CBS affiliate WREG.

The Court Clerk also reportedly could not comment on the case as it involved a juvenile under 14 years old.

The 12-year-old's parents could not be reached for comment.
