Girl, 8, tried to stop mother from stabbing younger sister to death, say prosecutors

CHICAGO — An 8-year-old Chicago girl watched in horror as her mom butchered her 5-year-old sister. The youngster tugged at her mother’s hair in a desperate attempt to get her to stop, prosecutors said.

Grisly new details have emerged in the slaying of Serenity Arrington, who was fatally stabbed Saturday in the family’s home, reportedly at the hands of her mother, Simone Austin, according to reports. 

Both girls were in Austin’s bedroom, when the mom asked her eldest daughter to leave the room. Prosecutors said the older girl watched through a missing doorknob as her mother grabbed a serrated knife from beneath a pillow and began stabbing Serenity, the Chicago Sun-Times reported.

The 8-year-old girl ran into the room to save her sister, yanking her mother’s hair, as the 5-year-old apologized and begged her mother to stop, prosecutors said.

The older girl then ran out of the East Garfield Park apartment where she, her sister and Austin had been living with Austin’s father. As she ran from their home she started yelling that her mother killed her younger sister, the Chicago Tribune reported.

She later told her grandfather that “mommy stabbed her little sister,” according to Assistant State’s Attorney James Murphy.

Prosecutors said Austin proceeded to carry Serenity’s naked, bloodied body outside, where she told at least one person and a paramedic that she “did it” and “was sorry,” authorities said.

Prosecutors gave no possible motive for the attack during Monday’s bond hearing.

But Austin’s 8-year-old daughter described a prior incident when her mother paced around with a knife in hand after she and her sister spilled eggs, the Tribune reported.

“And you never know what can happen,” Murphy told a judge, recalling the 8-year-old’s comment to investigators.

An autopsy determined Serenity, who was pronounced dead at a hospital, died from multiple stab wounds to the neck. Prosecutors said one wound to her throat was so deep that it almost went through the back of her neck, WBBM reported.

Austin, 27, was charged with first-degree murder and held without bail, FOX reported. She is due back in court on Oct. 19.
