The FBI said Wednesday that it shared the autopsy results with the family of a Mississippi man who was found hanging from a tree last month.

The Associated Press noted that the agency would not say if the death of Otis Byrd, 54, was a homicide or suicide.

"At each milestone in this case, the FBI's first step is to personally brief family members," Don Alway, special agent in charge of the FBI in Mississippi, said in a statement.

Through their attorney, Byrd’s family said that they do not believe he took his own life and they want more information about the case.

"Otis Byrd was found dead three weeks ago and the family still has limited information," Attorney Dennis Sweet IV said according to The Clarion-Ledger. "The family wants answers. We cannot allow the death of a man hanging from a tree to be swept under the rug."

Byrd was found hanging by bed sheet not far from the property he rented in Claiborne County’s Port Gibson. He has been missing for nearly three weeks before he was found.
