The FBI is consulting with its behavioral analysis unit as it continues investigating the hanging death of a black man in Mississippi.

Jason Pack, supervisory special agent for the FBI's Jackson, Mississippi, office, said Monday that it could be days before investigators receive an autopsy report for 54-year-old Otis Byrd. The report is expected to show whether Byrd was killed or committed suicide.

Officials have said 30 state, local and federal investigators are on the case.

Meanwhile, about a dozen people gathered Monday in downtown Port Gibson to show support for Byrd's family. They called on authorities to thoroughly investigate the death.

Byrd's body was found Thursday, hanging by a bedsheet tied to a tree in a rural area outside Port Gibson.
