Florida authorities have yet to rule what killed Augusta-native Philip Cameron Christian while he was on a college spring break trip to Destin, Fla.
Officials initially expected an autopsy would be completed Tuesday. According to Okaloosa County sheriff's spokeswoman Michele Nicholson, however, authorities are still awaiting toxicology reports, which could take up to six weeks.
Christian, a 23-year-old Georgia Southern University student, was discovered not breathing around 5 a.m. Sunday. Friends told authorities there had been a party Saturday night and that Christian had gone to sleep around 1 a.m.
Christian is a 2006 graduate of Westside High School.
