"UNLV Shooting: Personal Attacks and Frightening 911 Calls Unveiled, Campus Security Measures Strengthened"
Days before the shooting at UNLV that killed three professors, the alleged gunman, Tony Polito, published a document on his website containing personal letters and his opinions on higher education. The letters included personal attacks on educators and accused them of wrongdoing. Polito had applied for jobs at several Nevada System Higher Education institutions and was denied. Police discovered that Polito sent 22 letters with no return address, one of which contained an unknown white powder substance. The powder was later deemed harmless.
