VERNON HILLS — A 14-year-old suburban Chicago girl has pleaded not guilty to first-degree murder in the stabbing death of her half-sister.
The plea was entered on Friday in a Vernon Hills juvenile court.
The Associated Press isn't identifying the girl who died to protect the identity of her 14-year-old half-sister. She's charged as a juvenile in the Jan. 21 slaying at a Mundelein home. The AP typically doesn't publish the name of juveniles who are accused of crimes.
Prosecutors have said the teenager stabbed the younger girl more than 30 times and told investigators her sister didn't appreciate all she'd done for her, including doing the younger girl's chores.
They lived in the same Mundelein home and attended the same Lake County school.
