Jefferson City, Nov 19 (THAINDIAN NEWS) Looks are deceptive, for this 15 year old school girl who calmly plotted a murder for almost a week and even managed to carry out the murder of a 9 year old just for the thrill of it.

On Oct. 21, Alyssa Bustamante strangled her 9-year-old neighbor Elizabeth Olten without any provocation, cut the girl’s throat and stabbed her, prosecutors said.

“Ultimately, she stated she wanted to know what it felt like,” Missouri State Highway Patrol Sgt. David Rice testified Wednesday during a court hearing over the slaying.

David Rice, had interviewed Alyssa Bustamante after Elizabeth was reported to be missing. She confessed to the police investigators and even led them to the fourth grader’s well-concealed body in a wooded area near their neighborhood in St. Martins, a small town west of Jefferson City.

A Cole County judge ruled Wednesday that ‘Bustamante, who has been held in Missouri’s juvenile justice system, should be tried as an adult’. A few hours later, she was indicted on adult charges of first-degree murder and armed criminal action for allegedly using a knife to kill Elizabeth. A judge later entered a not guilty plea on Bustamante’s behalf and referred her to the public defender’s office.
