A female relative of 7- and 9-year-old sisters was arrested last night after stabbing the girls in their home. Lisa Turkki, 39, had been called to watch the two girls in their Katonah home while their parents, Eva and Joseph Kelly, who were down the street at a Dr. John concert at the time. Police showed up after getting a 911 call from the home, and found the girls lying in the kitchen in pools of their own blood.

The girls are currently in critical condition after surgery at the Westchester County Medical Center and Turkki was charged with two counts of first-degree assault. Fox says the scene was reportedly "gruesome," and specialized crews were brought in to clean the scene after evidence crews had collected everything they needed. The Kelly's live at 85 Girdle Ridge Road, just down the block from Martha Stewart.
