COOK COUNTY, IL. (THECOUNT) — Simone Austin has been identified as the Chicago mother charged with first-degree murder after she fatally stabbed her 5-year-old daughter, Serenity Arrington, in their home Saturday.

At a bond hearing on Monday, prosecutors said Austin was at home the morning Serenity died with the little girl and her 8-year-old sister.

The sister was allegedly told to leave the room before Austin cut Serenity’s neck with a knife she had under a pillow. Her sister watched through the keyhole in the door.

Austin then laid Serenity out in front of the home and told the officers and fire personnel who arrived that she did it and was sorry, prosecutors say.

Prosecutors say she then laid Serenity out in front of the home, and when police and fire personnel arrived, she told them she did it and that she was sorry.

The sister screamed when she saw Austin stabbing Serenity.

The sister tried to pull Austin off Serenity by her hair, prosecutors say.

“Keep that child in your thoughts and prayers because obviously this will be extremely difficult for the rest of her life,” said Police Chief of Detectives Brendan Deenihan.
