The details of a near-lethal slumber party last weekend in Waukesha, Wisconsin, are sending shockwaves throughout the country. On Monday, two 12-year-old girls were charged as adults for attempted homicide after they allegedly stabbed a friend 19 times at a sleepover party. Morgan Geyser and Anissa Weier were apparently motivated by slender man demon creature reading horror and death-related websites and had supposedly planned to kill their friend for months. Waukesha Police Chief Russell Jack said, “One suspect held the victim down while the other suspect stabbed her 19 times in the arms, legs, and torso.” Geyser and Weier are each being held in jail on $500,000 bail. The victim is in stable condition.
