Mundelein, IL, United States (4E) – A girl, 14, was charged with first-degree murder Wednesday for allegedly stabbing to death her half-sister, 11, 30 times, according to prosecutors.
The girl initially told Mundelein police at the station that she saw a man stabbing her sister and he ran off from the house upon seeing her. She later confessed to the killing committed past 8 a.m. Tuesday at the victim’s bedroom after investigators told her strands of hair found in the crime scene will identify the killer.
The girl’s motive was anger over her sister for not appreciating what she had done to her, including making dinner six times, said Assistant State Attorney Claudia Kasten during a detention hearing for the young suspect also attended by her mother. The teen also said she and her sister had a fight Monday night in which she was hit by the victim.
Lake County Coroner Thomas Rudd said a fillet knife was used in the killing and the victim had wounds indicating she tried to defend herself.
After stabbing her sister to dead, the suspect washed her hands and called her mother, who was at work. Her mother told her to call the police, who arrived around 8:30 a.m., Kasten said.
The initial account of the suspect prompted police to lock down three schools near the girl’s house.
