A 17-year-old Staten Island resident is being held on $250,000 after allegedly stabbing her 14-year-old brother. The Advance describes, "According to a law enforcement source, the two fought nearly every day, and Sunday morning was no different -- Rodney had overslept, and Miss Tyler went to wake him up. That sparked an argument, the source said, which escalated into violence. Miss Tyler grabbed a butcher knife and a steak knife." Although their mother tried to intervene and Tyler dropped the butcher knife, she "held onto the steak knife, raised it over her head, and reached over her mother's shoulder," allegedly plunging it her brother's chest and then pulling it out.
