The notorious schoolyard shooting became known as the Westside Middle School massacre. It began with one of the two boys setting off a false fire alarm in order to lure out students & faculty members out into open ground. They then laid down near a wooded area dressed in camouflage & began the slaughter. A total of five people—which comprised of four female students & a teacher—were killed. The teacher was 32-year-old Shannon Wright, who threw herself in front of a sixth-grader & was shot twice when saving the little girl. She died later on during surgery. But this wasnt enough for the cousins. Ten additional people were injured; nine students & another teacher. A recorded 27 shots total were fired that day. It was a horrific scene as friends gathered up the bodies of their bloodied classmates while waiting for emergency support. Some were in shock & could not take in what had just occurred in the schoolyard. Its still unsure as to how the murderers gained access to their weapons. Police said Mitchell—who broke up with a girl at school—made threats earlier in the week, saying, “Tomorrow you will find out if you live or die”. Andrew & Mitchell would be charged with five counts of capital murder in Juvenile Court & after turning 18, would be moved to a full correctional facility.\rbr\rbr6: Mary Bell\rbrMay 25th, 1968: the day before her 11th birthday, a girl named Mary Bell is convicted of strangling a young boy to death named Martin Brown. It was believed that she committed this homicide alone. Then two months later, on July 31st, 1968, Mary Bell strikes again; this time with her friend Norma. The two girls targeted a three-year-old infant named Brian Howe. The resulting interrogation of Mary Bell & Norma completely contradicted each other, as the girls were too young to re-tell a story. Police reports state that not only did Mary Bell use a pair of scissors to cut off pieces of her victims hair & part of his genitals, but she also carved an “N” onto his stomach, then later on went back to turn the “N” into an “M”. There was no evidence of foul play from the murder of their first victim, Martin Brown, & thus it was originally ruled as an accident. But in the end, police finally realized the connection between the two strangulations. Mary Bell & Norma were charged with two counts of manslaughter. In 1980, the court ordered anonymity for Mary Bell & she was released. 23 years later, Mary Bell & her daughter would be awarded anonymity for life.\rbr\rbr5: Jesse Pomeroy\rbrAt 14 years old, Jesse Pomeroy murdered a four-year-old boy & was eventually arrested for this horrific . His violent nature began three years earlier with the ual torture of seven other boys. Thus, he became known as “The Boston Boy Fiend.” Pomeroy was sentenced to a childrens reform school, but was released early for those crimes. But it didnt take long for Jesse to return to his killing spree. He went on to disfigure & execute a ten-year-old girl who was visiting his mothers store. A month later, four-year-old Horace Mullen was kidnapped by Pomeroy. Jesse started & ended his deadly deed in a swamp outside of town by slashing him savagely with a knife & nearly decapitating his victim. His strange appearance of having a milky white eye along with his previous abhorrent behavior put him on the polices radar. After being shown the body & asked if he had done it, Jesse responded with, “I suppose I did.” He later pled guilty to the murder of the ten-year-old girl, as her body was found buried in his mothers cellar. Jesse Pomeroy was condemned & sentenced to death. But his sentence was altered to 40 years of solitary confinement due to a public outcry against dooming children to the death sentence.\rbr\rbr4: Jon Venables & Robert Thompson\rbrYou name it, they can steal it.
