12-year-old girl charged with murder, accused of suffocating 8-year-old cousin in bed

MEMPHIS, Tenn. (WREG) – A 12-year-old girl in Humboldt, Tennessee, is being charged with first-degree murder after prosecutors say video shows her suffocating her 8-year-old cousin in a bunk bed they shared.

The girl, who will turn 13 next week, allegedly used bedding to suffocate her cousin, then cleaned up the victim and repositioned her body, say investigators who reviewed home security video of the incident.

The victim's mother, Rayana Smith, identified her as Demeria Hollingsworth.
