Yale killing, Annie Lee and Ray Clark

I think the murder of ms Annie Lee can probably be attributed to feelings of resentment and underachievement, as Mr Clark dealt with the Ivy League standouts. I'm sure an elitist mentality existed with the faulty and students and by him being just a "rat feeder" and "cage cleaner" animosity on his part had to fester. I think also race and gender may have played a part, as he felt dwarfed by a women and minority, in terms of achieve and social standing.
