Mundelein murder: Teen felt resentful, stabs 11-year-old sister

A Mundelein murder happened in the Chicago-area Tuesday morning when a teenage girl expressed her resentment towards her younger sister in a deadly way.

According to a Jan. 23 UPI report, a 14-year-old girl has been charged with first-degree murder for the stabbing death of her 11-year-old half-sister. Identities of both have been withheld due to their ages.

The violent killing took place at the girls' home in Mundelein, which is a village around 40 miles northwest of Chicago. Police said the teen stabbed her younger sister by allegedly using a small kitchen knife. There were over 30 slashes and cuts on the victim. In the beginning, the teenager blamed the attack on an intruder, but she later confessed that she did it. The girl's motive had to do with feeling unappreciated.

As the report stated, the teen suspect called police around 8:30 a.m. Tuesday and said a girl had been stabbed. Police arrived at the scene and discovered the 11-year-old on the bedroom floor with the knife lying next to her.

Mundelein Police Chief Eric Guenther confirmed that both girls were home alone when the attack happened. The State Attorney said authorities may move the Mundelein murder case to adult court, which will take weeks before the final decision is made.

Siblings typically fight a lot if they do not get along or if one resents the other. Competing for attention -- especially from the parents -- can be paramount for kids. Fortunately, an instance like the Mundelein murder case is a rare occurrence in sibling rivalry.
