14-Year Old Girl Stabs 11-Year Old Sister 40 Times Because She Wasn’t Thankful .

                                                                                                                                                                                An 11-year-old Illinois girl was stabbed 40 times by her 14-year-old sister, police say, and the reason why has many in the small Chicago-area community of Mundelein reeling in disbelief.

Police found the 11-year-old girl unconscious and in need of medical attention in an upstairs bedroom of the dwelling Tuesday morning. She later died.

Because the sister, who called police, initially told officers an intruder was to blame for the attack, authorities briefly placed three schools on lockdown.

The truth, when it emerged, was even more shocking.

The 14-year-old, authorities say, repeatedly and fatally stabbed the victim -- her half sister -- with a kitchen knife because the teen thought she was ungrateful.

"This incident is a heart breaking tragedy that defies understanding," said Mundelein Mayor Steve Lentz. "I am asking the Chicagoland area, please pray for us. Pray, first of all, for the family that has been devastated by this."

A group called "Mundelein Moms" is raising money for the girl's funeral and said it raised $6,381 in just one day. There also is an effort to have residents leave their lights on Friday night in remembrance.
