A Waukegan mom charged with fatally stabbing her 6-year-old daughter initially told police the girl was possessed, attacked her with a knife in bed and slammed her into a wall before the mother grabbed the weapon and slashed the girl's neck, Lake County prosecutors said in court Tuesday.

Nelly Vazquez-Salazar, 25, later admitted there was no attack and that she stabbed her daughter, Evelyn Vazquez, after she awoke and found the girl on her bed holding a knife, they said.

Sobbing throughout her bond hearing, Vazquez-Salazar listened through a Spanish interpreter as prosecutor Stephen Scheller laid out to Circuit Judge Dan Shanes the details to support first-degree murder charges against her.

"By all accounts, this was an intelligent, vibrant and beautiful little girl," said Scheller, head of felony review for the state's attorney's office. "The defendant claimed she was possessed by a demon. . . . In fact, judge, she was an angel."
