Mundelein murder: Girl, 14, brutally stabs 11-year-old half-sister 40 times

The Mundelein murder of an 11-year-old girl, who was brutally stabbed 40 times by her 14-year-old half-sister, has shocked the suburban Illinois town. A 911 call came into the Mundelein police station about 8:30 a.m. on Tuesday from the older half-sister reporting that an intruder had attacked the younger girl.

According to The Inquisitr on Jan. 23, the responding officers walked into the horrific murder scene of an 11-year-old girl with the 14-year-old girl claiming this attack was done at the hands of intruder. Police immediately locked down the schools in the area because a murderer was on the loose, but the lockdown lasted only 15 minutes. There was no need to look for a murdering intruder because the person who attacked and killed the 11-year-old girl was her half- sister.

The 14-year-old confessed once she was told by the detectives questioning her at the police station that they may have a way of identifying the killer. Police told the teen that the dead half-sister had strains of hair from the intruder in her hand that should lead them to the identity of the killer. The girl then told police she had killed her sister because she “was ungrateful.” Other than saying that her sister was “ungrateful” the motive for this unimaginable crime between two young siblings is unknown.

She told the police that they had argued the night before and when she woke up on Tuesday, she was still mad. She went downstairs and got a knife and “with each stab wound, she said she (the younger sister) was not thankful for what she (the older sister) had done.”

The 14-year-old said this during a detention hearing in a juvenile court where she was charged with first-degree murder. It is not decided yet if she will be charged as an adult in this case. Witnesses in the courtroom noted the blank stare of the 14-year-old, who didn’t show any sign of emotion during the majority of the hearing. As the details of the brutal attack were divulged in court, the girl’s eyes appeared to weld up and her face became red in color.

This murder was a shock to one of the neighbors who said that the girls were not only half-sisters, but good friends. They were often seen in the neighbor together or in their yard practicing cheer-leading together.

This killing was indicative of an act of rage, as 40 stab wounds is an overkill move on the part of the 14-year-old. This crime is eerily similar to the crime where a 12-year-old boy killed his eight-year-old sister in May of last year. He too reported that an intruder had come in and killed his sibling, but that is not what happened.
