CHAPEL HILL – The UNC fraternity into which a student who died last year was pledging is under investigation.

According to WRAL, the Alpha-Alpha Chapter of Chi Phi has been suspended from campus pending an investigation into alcohol violations and inappropriate new-member activities. The chapter is being investigated by the national governing body of Chi Phi.

Eighteen-year-old David Palmer Shannon died last year in Carrboro after falling 40 feet from machinery at a concrete-mixing plant. Carrboro police originally said they believed Shannon was alone at the time of the fall, but the investigation remains open. An autopsy found Shannon had a blood alcohol level three times the legal limit.

Chi Phi had just gotten off probation the day before Shannon died, according to Carrboro Police.

UNC Vice Chancellor for Student Affairs, Winston Crisp says the University fully supports the investigation and has a “zero tolerance” for actions that threaten the health and safety of students. However, he says the suspension of Chi Phi is not directly related to Shannon’s death.
