Authorities are now trying to figure out why a 16-year-old went on a stabbing spree in a Pennsylvania high school yesterday. The FBI says they have searched the suspect’s home and have taken his and his parents’ computers and a cell phone as they look for a motive. 16 year old Alex Hribal stabbed 20 students and a security officer with two kitchen knives at Franklin Regional Senior High School just outside of Pittsburgh. In an interview earlier today, Hribal’s attorney says the suspect was a well liked student and not a loner. Hribal has been charged as an adult and is facing multiple charges including aggravated assault and attempted homicide
