Girl, 14, stabs sister 40 times

An 11-year-old Illinois girl was stabbed 40 times by her 14-year-old sister, in a small Chicago-area community. Police found the 11-year- old girl unconscious and in need of medical attention in an upstairs bedroom of the Illinois suburb 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 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. The teen said she cooked dinner for her younger sibling and performed other chores. She was also angry that the 11-year-old girl had recently hit her. The night before the attack, the teen thought about it for about 10 or 15 minutes, then went downstairs and grabbed a knife. After the stabbing, she took a shower to wash off the blood, called police and made up the story about the intruder. The 14-year-old was arrested and was charged with murder. The case is in juvenile court and a decision could be made in the future to move the case to adult court. Those who knew the girls said they lived at the home with their mother. Neighbors said the siblings seemed close. The girls were often seen playing together and practicing cheerleading routines.

In Other News A last-ditch push to keep a convicted cop killer alive failed Wednesday night when the U.S. Supreme Court denied a motion to stay his execution. Edgar Tamayo Arias, a Mexican national, was executed last night.

U.S. Secretary of State John Kerry has also weighed in on Tamayo's case, arguing that setting an execution date is "extremely detrimental to the interests of the United States.“ "I want to be clear: I have no reason to doubt the facts of Mr. Tamayo's conviction, and as a former prosecutor, I have no sympathy for anyone who would murder a police officer," Kerry wrote. "This is a process issue I am raising because it could impact the way American citizens are treated in other countries.“ A 17-year-old male was charged Saturday as an adult with aggravated assault and other charges over a shooting the previous day at a Philadelphia high school.
