Ole Miss asked the national headquarters of Sigma Phi Epsilon to investigate the 130-member Ole Miss chapter after the noose incident. Sig Ep (and Ole Miss) found evidence of underage drinking, bad behavior, and serious hazing, and pulled the Ole Miss chapter's charter.
Ole Miss was one of Sig Ep's 342 chapters.
Our local Sig Ep chapter built a $3+M house in Greek housing after living for years off-campus. They lost their charter after one semester in the house.
Now the house is used to house students looking to start a business.
